Abstract

NEW MATERIAL:A cembrene type diterpene of the formula (R is CH2OH, CHO, COOH); individual compounds are called sinulariol C, sinularial A and sinularic acid A, respectively. USE:It can be used for treatment and prevention of cancers, just like sarcophytol A, B which inhibit the carcinogenic promotion process and as an intermediate of these compounds. PREPARATION:For example, Sinularia mayi is dehydrated until the viscous fluid is lost from the body surface, minced, extracted with a solvent. Then, the extract is subjected to a variety of chromatography such as silica-gel column chromatography to effect separation and purification whereby the compound of the formula is obtained.

Example 1 A 15.8 yen (15.8 yu) fish harvested in Ishigaki Island, Okinawa in June 1980 was dehydrated, chopped into #l pieces, and first mixed with 50 tons of methanol and then 50 tons of chloroform.
Dispense the mixture thoroughly with methanol (volume ratio 2:1) at room temperature. The dried residue of Tsukuda Mk, m after the bath medium was distilled off under 0.0 Tsukuda pressure was dried in a 5-year-old tank (however, it handles salt production).
