据报道,已从寄生植物中药锁阳(Cynomorium songaricum)中分离出甾类、三萜、果糖糖苷、黄酮及缩合鞣质类等成分。本次从其茎中又提取出2种新的酚类化合物,并对其结构进行了确证。 锁阳茎(2.0kg,中国天津产)切片,依次用甲醇、70％丙酮室温提取,合并提取物悬浮水中,再用乙酸乙酯萃取。乙酸乙酯和水层部分分别上硅胶柱、MCI-gel CHP 20P、 It has been reported that triterpenoids, triterpenoids, fructosides, flavonoids, and condensed tannins have been isolated from the parasitic plant Cynomorium songaricum. Two new phenolic compounds were extracted from their stems and their structure was confirmed. Cynomorium stalk (2.0 kg, produced in Tianjin, China) was sliced, extracted with methanol and 70% acetone at room temperature, and the combined extracts were suspended in water and extracted with ethyl acetate. The ethyl acetate and water layers were separately applied to a silica gel column, MCI-gel CHP 20P,
