The present invention relates to a novel tannin useful as a pharmaceutical and a method for producing the same. Tannins are widely distributed in the plant kingdom and have long been known to have astringent properties, and have been widely used as an astringent and as a tanning agent to transform hides into leather. Tannin is a trace component of plants with a molecular weight of about 600 to 2,000, and has a complex structure, which, combined with the difficulty of isolation and purification, has delayed research. On the other hand, it has been conventionally known that plants such as elms have useful medicinal effects based on enzyme inhibitory effects and the like. In order to search for medicinal components in these plants, the present inventors isolated and obtained the components contained in these plants and investigated their pharmacological effects, and luckily discovered that a new tannin has an enzyme-inhibiting effect. The invention has been completed. The compound according to the present invention has the effect of reducing the activity of enzyme proteins in the body by binding to them. The compound according to the present invention includes elm, elm,
From plants such as cinnamon bark, cinchona bark, cane bark, chestnut bark, etc.
It can be easily obtained by known methods such as extraction with acetone, partitioning between ethyl acetate and water, or column chromatography. These methods can be summarized as follows, for example.
