Example 1 : Isolation of 7Z, 10Z, 13Z-cyclohexadecatrien- 16-olide from raw fruits of passion fruit

After removing seeds from 20 kg of raw fruits of passion fruit (purple species), extraction was carried out at room temperature for 24 hours by adding 10 kg of diethyl ether. Next, diethyl ether was evaporated by carrying out distillation under normal pressure at a liquid temperature of 35°C, and high vacuum distillation was further carried out in order to remove low boiling point compounds. The distillation was completed when the degree of vacuum was 120 Pa and liquid temperature was 97°C and when the overhead temperature was lowered from about 70°C to about 50°C.

Subsequently, this was divided into 5 fractions by a silica gel column chromatography (elution solvent; hexane:ethyl acetate = 98:2 in volume ratio) and each fraction was analyzed by a gas chromatography-olfactometry, thereby obtaining a fraction having a musk aroma at a retention time of from 30 to 45 minutes.

This fraction was further fractionated by a reverse phase thin-layer

chromatography fractionation (developing solvent volume ratio, methanokwater = 20: 1). After the development, this was divided into 3 fractions based on the separation patterns (UV absorption) of the thin-layer chromatography, and the odor components of each fraction were extracted with methanol. The extracted odor components were analyzed by a gas chromatography-olfactometry, methanol in the fraction having a musk aroma was evaporated and then the residue was purified by a high performance liquid chromatography (elution solvent; methanol: water = 8:2 (volume ratio)) to obtain 7Z,10Z,13Z-cyclohexadecatrien-16-olide (purity 94%).
