Description

A kind of sesquiterpenoid and its preparation method and application
Technical field
The present invention relates to the active components of plants field, relate in particular to a kind of sesquiterpenoid and its preparation method and application.
Background technology
Wide leaf Chloranthus spicatus (Chloranthus henryi Hemsl.) is Chloranthaceae (Chloranthaceae) Chloranthus (Chloranthus) plant, has another name called Herba Chloranthi Henryi (Herba Choranthi seu Lysimachiae), Four Heavenly Kings, great Ye and oneself, careless rhinoceros.Wide leaf Chloranthus spicatus is perennial herb or undershrub, high 40-65cm (even can up to 100cm), and root stock is sturdy, and chocolate has several elongated brown fibrous roots; Stem is upright, and joint obviously expands, and leaf, to life, is born in stem top for common 4, and idol has 6 (being verticillate shape) wide ellipse or obovate, long 9~18cm, and wide 5~9cm, give birth on inflorescence spike top and armpit is given birth to, common not tally or total shape branch, drupe is spherical; In 4~November of flowering fruit bearing stage, be born under hillside in dark and damp ground and the other thick grass of cheuch.Be distributed in the provinces and regions (Ye Guorong such as Jiangsu, Anhui, Jiangxi, Fujian, Hunan, Hubei, Guangdong, Guangxi, Sichuan, Guizhou, Zhejiang, Shaanxi, Gansu, Peng Dewei. the herbal textual of careless rhinoceros, CHINA JOURNAL OF CHINESE MATERIA MEDICA .2001,26 (3): 212-213.).Wide leaf Chloranthus spicatus have dispel the wind, dehumidify, invigorate blood circulation, the effect of stagnation resolvation, can be used for the treatment of arthralgia due to wind-cold-dampness pathogen BI syndrome, rheumatic numbness, pain, menoxenia, wound, cough due to wind and cold and carbuncle pyogenic infections from tumour or sore etc.
The research of Chloranthus plant chemical ingredient is more, is mainly sesquiterpenoid, has good prospect in medicine.As far back as 1978, the people such as Masaaki Uchida separate and obtain 2 ring eudesmane type sesquiterpene lactones from Herba Pileae Scriptae Chloranthus glaberMakino, called after chloranthalactone A and B (Uchida M, Kusano G, Kondo Y, Nozoe S, Takemoto T Two newsesquiterpenoids from Chloranthus glaber Makino.Heterocycles, 1978,9 (2): 139-44.).
Within 1979, with Jun Kawabata in 1981 etc., reported to separate from Herba chloranthi japonici to obtain 2 ring eudesmane type sesquiterpene shizukanolide A and dehydro-shizukanolide (shizukanolide B), wherein dehydro-shizukanolide is exactly the chloranthalactoneA of Masaaki Uchida report.The active testing result shows that dehydro-shizukanolide has medium anti-mycotic activity ((a) Kawabata J, Tahara S, Mizutani J, Furusaki A, Hashiba N, Matsumoto T.Shizukanolides, two sesquiterpenoids from Chloranthus japonicus (Chloranthaceae) .Agric.Biol.Chem., 1979, 43 (4): 885-887. (b) Kawabata J, Tahara S, Mizutani J.Isolation and structure elucidation of four sesquiterpenesfrom Chloranthus japonicus (Chloranthaceae) .Agric.Bioc.Chem., 1981, 45 (6): 1447-1453.).
Separating the Herba chloranthi japonici that the people such as Masaaki Uchida produce from Japan again and obtain 5 ring eudesmane type sesquiterpenes, is respectively chloranthalactone A-E.By degraded, the absolute configuration of measured ORD history estimating chloranthalactone A and B.Chloranthalactone A-C demonstrates stronger cytotoxicity, IC to mouse Lymphosarcima L-5178Y cell 50be respectively 2.5,1.0-2.5 and 20 μ g/mL (Uchida M, Koike Y, Kusano G, Kondo Y, Nozoe S, Kabuto C, Takemoto T.Studies on the constituents of Chloranthus spp.III.Sixsesquiterpenes from Chloranthus japonicus.Chem.Pharm.Bull., 1980,28 (1): 92-102.).
Summary of the invention
The invention provides a kind of sesquiterpenoid, this compound is to extract the natural active matter obtained in wide leaf Chloranthus spicatus plant, has anti-oxidant activity.
A kind of sesquiterpenoid, its structural formula is suc as formula shown in (I):
Figure BDA0000114500370000021
The invention provides the preparation method of described sesquiterpenoid, comprise the following steps:
