Abstract

NEW MATERIAL:A tannin shown by formula I (R25 and R26 are H, group shown by formula II or formula III). EXAMPLE:A compound shown by formula IV (R25=R26=H, brown amorphous powder.) USE:A drug and antiallergic which is bonded to enzyme protein in body, has lowering action on activity of the protein and shows anti-hyaluronidase activity. The titled compound is observed to have inhibitory action on herpes virus growth and expected to be used as an antiviral agent. PREPARATION:A plant such as bark of Kandelia Candel Druce, Sanguisorba Radix, bark of Quercus salicina Blume, tea leaf, pomegranate leaf, bark of Quercus acutissima, etc., is extracted with acetone and subjected to well-known method such as partition with ethyl acetate : water or column chromatography to give a compound shown by formula I readily.

EXAMPLE 9 kg of mehirugi bark is extracted three times with 70% aqueous acetone 40β and the acetone is distilled off. After distilling off, the precipitate that precipitates out is filtered off. The filtrate is separated 5 times with 31 portions of n-butanol, the n-butanol soluble substances are collected and washed with water, and Celite is added and air-dried. This is packed into a column and eluted with acetone to obtain an acetone-soluble substance. When this was further separated and purified using Sephadex LH-20 and Diaion HP-20 chromatography, 90 mg of brown amorphous powder was obtained.
