来る。 In the kneading method, menatetrenone and dimethyl-β-cyclodextrin are weighed out at a molar ratio of 1:1 to 1:10, and in a dark room, purified water is added to form a sol, and then the mixture is mixed until it becomes a paste. After thorough kneading, the mixture is dried under reduced pressure to obtain a powdery clathrate compound. There are no particular restrictions on the kneading temperature; room temperature is sufficient, and the kneading time depends on the amount of material to be prepared.
0.5 to 2 hours is sufficient. The clathrate compound thus obtained can be purified if necessary.

性質を示す。 Furthermore, the powder X-ray diffraction pattern of vitamin K 2 -dimethyl-β-cyclodextrin (molar ratio 1:1) is shown in FIGS. 3 and 4. As is clear from Figure 3, the peak of a physical mixture is simply observed as the sum of both components, but in the case of clathrate compounds, the peaks of each component disappear and a new peak is created, as shown in Figure 4. The appearance showed different diffraction patterns. Moreover, the peak of the clathrate compound is broadened compared to that of the physical mixture, indicating that it has undergone amorphization. Other molar ratios (1:3, 1:
5, 1:10) shows similar properties.

FIG. 5 shows the results of measuring the dissolution behavior of the sample using the powder method. Each clathrate exhibited excellent solubility, reaching solubility equilibrium in 2 to 3 minutes, and it was observed that the higher the dimethyl-β-cyclodextrin content in the clathrate, the higher the supersaturation concentration.
