Studies on Active Antiallergic Constituents in Lithocarpus polystachyus(Wall) Rehd
【摘要】 从云南甜茶 [Lithocarpuspolystachyus(Wall)Rehd]的乙酸乙酯提取物中分离得到具有抑制透明质酸酶活性的 2个化合物 ,经光谱分析、化学反应和文献对照等方法 ,初步鉴定证实该有效成分为二氢查尔酮 - 2′- β -D -吡喃葡萄糖甙 (dihydrocharcone- 2′ - β -D - glucopyranoside)和二氢查尔酮 - 4′ - β -D -吡喃葡萄糖甙 (dihydrocharcone - 4′ - β -D - glucopyranoside)
【Abstract】 From the ethyl Acetate extract of Lithocarpus (wall) Rehd,the active constituents with strong inhibition on the activation of hyaluronidase were isolated and identified as dihydrocharcone-2′-β-D-glucopyranoside and dihydrocharcone-4′-β-D-glucopyranoside.
