从禾本科植物白羊草 (Bothriochloaischaemum(L .)Keng)干燥全草的乙醚提取物中共分离得到 4个化合物 ,通过光谱数据和理化性质分别鉴定为 β 谷甾醇 (Ⅰ )、丁二酸 (Ⅱ )、棕榈酸(Ⅲ )、苜蓿素 (Ⅳ ) .化合物 (Ⅰ～Ⅳ )均系首次从该属植物中分离得到
Four compounds were isolated from the ethyl ether extract of the dry grass (Bothriochloaischaemum (L.) Keng) grasses, which were identified as β-sitosterol (I) and succinic acid (II) by spectral and physicochemical properties. ), palmitic acid (III), alizarin (IV). Compounds (I-IV) were isolated from this genus for the first time.
