[0039] 1. Take 1.73kg of Japanese snake mushroom, chop it, soak it with 70% methanol at room temperature, filter it overnight, and concentrate the filtrate under reduced pressure with a rotary evaporator to obtain 223.7g of the total extract; dilute the extract with water and dilute it with ether Extraction, take the water phase, and then extract with ethyl acetate to obtain the dissolved part of ethyl acetate; pass the dissolved part of ethyl acetate through Chromatorex ODS, elute with water, and then elute with 10-80% methanol, collect 40-80% methanol to wash Remove liquid, recover methanol under reduced pressure, add a little methanol to dissolve the residue; then apply MCI-gel CHP20P, elute with water and then 10-80% methanol, collect 40-80% methanol eluate, recover methanol under reduced pressure, The residue was dissolved by adding a little methanol; then it was chromatographed on Sephadex LH-20, eluted with water and then eluted with 10% to 80% methanol, and 50% to 80% o...

Abstract

The invention provides a novel hydrolytic tannins of the pyran glucose category containing the gall acyl, particularly a 1,3-O-2-galloyl-6-O-(S)-caesalpinia digyna acyl-beta-D-glucopyranosyl dextrose. The chemical structure is as shown in formula (1). The compound of the invention can inhibit the proliferation of tumor; the compound has the better anti-tumor activity and can be used to prepare the anti-tumor drug.

Description

technical field [0001] The invention relates to the field of organic chemistry, in particular to glucopyranose hydrolyzable tannins containing galloyl groups. Background technique [0002] Tannins, also known as vegetable tannins, are a class of complex polyphenolic compounds widely present in plants, among which hydrolyzable tannins are esters or glycosides formed of phenolic acids and polyols. [0003] In 2001, Zhi-hong Jiang and Yoko Hirose found a variety of glucopyranose hydrolyzable tannins containing caffeoyl and galloyl groups in snake mushroom (Balanophora japonica Makino), such as: 1-O-(E) -Caffeoyl-3-O-galloyl-β-D-glucopyranose, the compound is a yellow amorphous powder, [α] D 15 -48.9°(c=0.8, MeOH), can be hydrolyzed into gallic acid and 1-O-(E)-caffeoyl-β-D-glucopyranose under the action of tannase; 3-O-(E) -Caffeoyl-4-O-galloyl-D-glucopyranose, the compound is a yellow amorphous powder, [α] D 15 -144.2°(c=0.7, MeOH), under the action of tannase, it can be ...
