从开花期的全能花(Pancratium biflorumRoxb.)的鳞茎和假茎液中分离出三个色酮,一个为已知成分2,4,6-三甲氧基苯乙酮,另外两个是葡萄糖氧基苯乙酮。切开新鲜的开花期的全能花的假茎,收集假茎液,这种粘滞的渗出液用含痕量的EDTA的甲醇处理。甲醇溶液在60℃水浴保温15min,使该液体中的酶灭活。用等体积的水稀释并在减压下浓缩至1/3体积。浓 Three chromones were isolated from bulbs and pseudostems of the flowering panicle (Pancratium biflorum Roxb.), one of which is known as 2,4,6-trimethoxyacetophenone, and the other two are glucose glucosides. Acetophenone. Fresh stems of pseudoflora of fresh flowering were cut and pseudostem was collected. This viscous exudate was treated with methanol containing traces of EDTA. The methanol solution was incubated in a 60°C water bath for 15 min to inactivate the enzymes in the liquid. Diluted with an equal volume of water and concentrated under reduced pressure to 1/3 volume. concentrated
