Abstract

NEW MATERIAL:The compound of formula I [R<11>-R<13> are H, galloyl group of formula II or group of formula III (the substituent group is bonded at arbi trary two positions; R<6> and R<7> are H or group of formula IV); R<14> is (di) hexahydroxydiphenol.glucose residue], formula V (R<21>-R<24> are H, methyl or group of formula II), formula VI (R<31>-R<34> are H or group of formula II) or formula VII. EXAMPLE:2,3-Hexahydroxydiphenoyl-6-O-galloyl-glucose. USE:An antienzyme agent useful as a drug. PREPARATION:The raw herb such as URAJIRO-GASHI (bark of Quercus salicina), KEIHI (bark of Cinnamomum cassia), etc., is extracted with acetone. The extract is partitioned with ethyl acetate and water, and the obtained ethyl acetate layer is purified by column chromatography to obtain the objective compound.

Description

【発明の詳細な説明】 本発明は医薬品として有用な新規タンニン及びその製造
法に関する。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel tannin useful as a pharmaceutical and a method for producing the same.

タンニンは広(植物界に分布し、収斂作用のあることが
古くから知られ、収斂薬として、また皮を革に変化させ
るなめし剤として多く用いられてきた。
Tannins are widely distributed throughout the plant kingdom, and have long been known to have astringent effects, and have been widely used as an astringent and as a tanning agent to transform hides into leather.

タンニンは分子量600〜2000はどの植物の微量成
分で複雑な構造を有しており、単離精製の困難さとあい
まって研究が遅れていた。
Tannin is a trace component of any plant with a molecular weight of 600 to 2,000, and has a complex structure, which, combined with the difficulty of isolation and purification, has delayed research.

一方、従来より、地楡等の植物が、酵素阻害作用等に基
