PERFUME COMPOSITION FOR EXPRESSING THE FRAGRANCE OF UME FLOWERS [Technical Field]
The present invention relates to a perfume composition having a fragrance like the characteristic fragrance of Japanese apricot flowers (also called as "ume flowers", hereinafter we call "Japanese apricot flowers"). More particularly, the present invention relates to a perfume composition, which contains an artificial synthetic substance, in addition to the fragrant components of
Japanese apricot flowers, determined by analyzing the fragrant components of white Japanese apricot flowers or red Japanese apricot flowers, and thus has a fragrance like the characteristic fragrance of Japanese apricot flowers and, at the same time, has high preference.
[Background Art]
Japanese apricot trees, Prunus mume Siebold & Zucc, are deciduous small trees belonging to the family Rosaceae, the order Rosaceae, and are native to China and distributed in Japan, China and Korea. Japanese apricot trees come in many varieties depending on the intended use thereof or the color of flowers or the shape of petals, and are classified, according to the color of petals, into white Japanese apricot trees having white flowers, and red Japanese apricot trees having red flowers.
To prepare products having a fragrance like that of Japanese apricot flowers, various methods can be
conventionally used. Examples of these conventional methods include a solvent extraction method of making absolute oils using the fragrant components of flowers, and a steam distillation method of making essential oils using the fragrant components. However, in these methods, high heat should be applied during the extraction process, complicated treatment processes are used so as to require a long period of time is required, and the fragrance of the product can be greatly different from the characteristic fragrance of flowers.
Recently, in order to overcome such shortcomings, a head space method and an SPME method were developed. Among them, the SPME (Solid Phase Micro Extraction; SUPELCO international, Vol.13, No.4, p.9-10) method is considered to be an excellent technology, which can analyze the fragrant components in a rapid and convenient manner without needing the use of solvent and the pretreatment of samples . [Disclosure] [Technical Problem]
The present inventors have made efforts to develop a product having a fragrance like that of Japanese apricot flowers, using the SPME method effective in analyzing the fragrant components of living natural materials. As a result, the present inventors have found out the fragrant components of white Japanese apricot flowers and red Japanese apricot flowers, but have found that a product having a fragrance like the fragrance of natural Japanese apricot flowers cannot be obtained only with a combination
of the fragrant components .
Accordingly, the present inventors have continued to study in order to a product having a fragrance like that of white Japanese apricot flowers or red Japanese apricot flowers and, as a result, a perfume composition, which contains, active ingredients, an artificial synthetic substance, in addition to the main fragrant components of
Japanese apricot flowers, can emit a fragrance like the characteristic fragrance of white Japanese apricot flowers or red Japanese apricot flowers and has high preference, thereby completing the present invention.
Therefore, it is an object of the present invention to provide a perfume composition, which can emit a fragrance like the characteristic fragrance of white Japanese apricot flowers or red Japanese apricot flowers and has high preference .

The sensory tests were conducted by professional perfumers and general persons, and the similarity of fragrance of the compositions to the fragrance of Japanese apricot flowers and the preference of fragrance thereof were evaluated through questionnaire survey.
[Advantageous Effects] As described above, the compositions according to the present invention contain the fragrant components of white Japanese apricot flowers or red Japanese apricot flowers, analyzed by the SPME method, and an artificial synthetic substance, and thus can emit a fragrance like the fragrance of natural Japanese apricot flowers and can also improve the preference of fragrance. [Mode for Invention]
Hereinafter, the present invention will be described in further detail with reference to the following examples. It is to be understood, however, that the scope of the present invention is not limited these examples, and other applications and modifications of the present invention will be obvious to those skilled in the art.
Reference Example 1: Analysis of fragrance of white Japanese apricot flowers
1. Analysis of fragrance of white Japanese apricot flowers using SPME method
White Japanese apricot flower branches having strong fragrance were selected and the fragrant components were
adsorbed to polyacrylate fiber coated with 85-jMii polyacrylate for SPME analysis and collected for 2 hours.
The collection of the fragrant components was conducted in a wild Japanese apricot tree grove, located at Daap-myeon, Gwangyang-si, Jeollanam-do, Korea.
After the fragrant components were collected, the fiber having the fragrant components collected thereon was sealed so as to prevent the volatilization of the fragrant components. The sealed fiber was put into the inlet of a GC-MS column, and then desorbed for 2 minutes and subjected to GC-MS analysis. The GC-MS analysis was carried out in the following conditions. Analysis conditions
Analysis instrument: HP 5890 II GC Detector: HP 5972 MSD

1-3: Analysis of fragrance and comparison of fragrance with red Japanese apricot flowers, conducted by professional evaluation group As can be seen in Reference Example 2, the perfume composition comprising the components analyzed by the SMPE method had no similarity to the fragrance of natural red Japanese apricot flowers. Thus, each of the fragrant components of red Japanese apricot flowers was subjected to sensory evaluation by a professional evaluation group consisting of perfumers. As a result, it was found that, among the fragrant components of red Japanese apricot flowers, six components, including benzaldehyde, which is the major fragrant component of fruits, such as cherries and almonds, benzyl acetate, which has sweet fruit fragrance and makes jasmine fragrance, benzyl alcohol, which has a light aromatic fragrance and is used to produce a fragrance like that of jasmine, gardenia or lilac, and cynnamaldehyde , cinnamyl alcohol and cinnamyl acetate,
which are the main components of cinnamon fragrance, were major components making the characteristic fragrance of red Japanese apricot flowers.
Example 1: Preparation of new perfume compositions having varying contents of main components of white Japanese apricot flowers
From the results of Reference Example 1, it could be seen that the main components of the characteristic fragrance of white Japanese apricot flowers were benzaldehyde, benzyl acetate and benzyl alcohol. Thus, in order to provide a perfume composition, which contains these three components to emit the fragrance of white Japanese apricot flowers and, at the same time, has high preference, the present inventors prepared new perfume compositions #1-6.
The perfume compositions #1-6 were prepared such that the ratio between these three components was maintained constant while the total content of these three components were changed in the range of 65-90t% (see Table 9) . [Table 9]
Example 2 : Sensory evaluation of perfume compositions prepared in Example 1
The six new perfume compositions, prepared in Example 1, were examined with respect to the similarity of fragrance to the fragrance of white Japanese apricot flowers and the preference of fragrance using sensory evaluation in the same manner as described in Reference Example 1. Meanwhile, after the comparative sensory evaluation of two perfume compositions was conducted, a breathing time of 5 minutes was given to eliminate olfactory paralysis. Sensory evaluation results for the similarity of fragrance between the new perfume compositions and white Japanese apricot flowers, and the preference of fragrance, are shown in Table 10 below. [Table 10]
As shown in Table 10 above, the perfume composition #3 , in which the content of the three main components was 75%, showed the highest similarity and preference among the six perfume compositions, but all the similarity and preference of the perfume composition #3 were lower than the average values (so-so) .
Example 3 : Preparation of perfume compositions having improved fragrance of white Japanese apricot flowers, based on analysis conducted by professional evaluation group
To improve the similarity and preference of the perfume composition #3, which was shown to be most similar
to the fragrance of white Japanese apricot flowers in Table
6 above, new perfume compositions were prepared by adding florol (tetrahydro-4-methyl-2- (2-methyl propyl) -2H-pyran-4- ol) , having a clean and soft floral fragrance, to the perfume composition #3 in which the total content of benzaldehyde , benzyl acetate and benzyl alcohol was 75%.
The florol was added at concentrations of 2%, 4%, 6%, 8% and 10%, and the other components were added so as to make a total content of 100%. These perfume compositions are shown in Table 11 below.
[Table ll]
Example 4 : Sensory evaluation of perfume compositions prepared in Example 3
The five perfume compositions #A, #B, #C, #1D and #1E, prepared in Example 3 , were examined with respect to the similarity of fragrance to the fragrance of white Japanese apricot flowers and the preference of fragrance by performing sensory evaluation in the same manner as described in Reference Example 1 above. Meanwhile, after the comparative sensory evaluation of two perfume combinations was conducted, a breathing time of 5 minutes was given to eliminate olfactory paralysis. Sensory evaluation results for the similarity of fragrance between the new perfume compositions and white Japanese apricot flowers, and the preference of fragrance, are shown in Table 12 below. [Table 12]
As can be seen in Table 12 above, 4-8 wt% florol was added to the main fragrant components of white Japanese apricot flowers, including benzaldehyde, benzyl acetate and benzyl alcohol, the resulting compositions could have a fragrance like that of white Japanese apricot flowers and show high preference (average of more than 3.5) .
Meanwhile, it could be seen that, when florol was added in amounts of less than 4 wt% or more than 8 wt%, the fragrance similarity and preference of the resulting perfume compositions were slightly higher than or not substantially different from those of the perfume compositions containing no florol (see #4 in Table 10) .
Example 5 : Preparation of new perfume compositions having varying contents of main components of red Japanese apricot flowers
From the results of Reference Example 2, it could be seen that the main components of the characteristic fragrance of red Japanese apricot flowers were benzaldehyde, benzyl acetate, benzyl alcohol, cinnamaldehyde, cinnamyl
alcohol and cinnamyl acetate. Thus, in order to provide a perfume composition, which contains these six components to emit the fragrance of red Japanese apricot flowers and, at the same time, has high preference, the present inventors prepared new perfume compositions #7-12.
The perfume compositions #7-12 were prepared such that the ratio between these six components was maintained constant while the total content of these six components were changed in the range of 65-90t% (see Table 13) . [Table 13]
Example 6 : Sensory evaluation of perfume compositions prepared in Example 5
The six new perfume compositions #7-#12, prepared in Example 5, were examined with respect to the similarity of fragrance to the fragrance of red Japanese apricot flowers
and the preference of fragrance by performing sensory- evaluation in the same manner as described in Reference Example 2. Meanwhile, after the comparative sensory evaluation of two perfume compositions was conducted, a breathing time of 5 minutes was given to eliminate olfactory paralysis. Sensory evaluation results for the similarity of fragrance between the new perfume compositions and red Japanese apricot flowers, and the preference of fragrance, are shown in Table 14 below. [Table 14]
As shown in Table 14 above, the perfume composition #8, in which the content of the six main components was 85%, showed the highest similarity and preference among the six perfume compositions, but all the similarity and preference of the perfume composition #8 were lower than the average values (so-so) .
Example 7 : Preparation of perfume compositions having improved fragrance, based on analysis conducted by professional evaluation group
To improve the similarity and preference of the perfume composition #8, which was shown to be most similar to the fragrance of red Japanese apricot flowers in Table
14 above, new perfume compositions were prepared by adding phenylisohexanol, having a delicate and attractive fragrance, to the perfume composition #8 in which the total content of benzaldehyde , benzyl acetate, benzyl alcohol, cinnamaldehyde, cinnamyl acetate and cinnamyl alcohol was
85%. The phenylisohexanol was added at concentrations of 2%, 4%, 6%, 8% and 10%, and other components were added so as to make a total content of 100%. These perfume compositions are shown in Table 15 below.
[Table 15]
Example 8 : Sensory evaluation of perfume compositions prepared in Example 7
The five perfume compositions #F, #G, #H, #11 and #1J, prepared in Example 7, were examined with respect to the similarity of fragrance to the fragrance of red Japanese apricot flowers and the preference of fragrance by performing sensory evaluation in the same manner as described in Reference Example 2 above. Meanwhile, after the comparative sensory evaluation of two perfume combinations was conducted, a breathing time of 5 minutes was given to eliminate olfactory paralysis. Sensory evaluation results for the similarity of fragrance between the new perfume compositions and red Japanese apricot flowers, and the preference of fragrance, are shown in Table 16 below.
[Table 16]
As can be seen in Table 16 above, 4-6 wt% of
phenylisohexanol was added to the main fragrant components of red Japanese apricot flowers, including benzaldehyde , benzyl acetate and benzyl alcohol, the resulting compositions could have a fragrance like that of red Japanese apricot flowers and show high preference (average of more than 3.5).
Meanwhile, it could be seen that, when phenylisohexanol was added in amounts of less than 4 wt% or more than 6 wt%, the fragrance similarity and preference of the resulting perfume compositions were slightly higher than or not substantially different from those of the perfume compositions containing no phenylisohexanol (see Table 14) .
