臭牡丹苯乙醇苷类化合物的分离鉴定

Isolation and characterization of phenylethanoid glycosides from Clerodendron bungei

摘要: 目的研究臭牡丹地上部分的化学成分。方法采用大孔吸附树脂、硅胶、凝胶柱色谱和高效液相色谱进行分离纯化，根据化合物的理化常数和光谱数据进行结构鉴定。结果从臭牡丹地上部分的乙醇提取物中分离得到10个苯乙醇苷类化合物，其化学结构分别确定为clerodendronoside (1), acteoside (2), isoacteoside (3), cistanoside C (4), jionoside C (5), leucosceptoside A (6), cistanoside D (7), campneoside I (8), campneoside II (9), cistanoside F (10)。结论化合物1为新化合物，化合物4～10为首次从该植物中分离得到。

Abstract: AimTo study the chemical constituents from Clerodendron bungei Steud. Methods The compounds were isolated and purified by various chromatographic techniques and identified by their physicochemical properties and spectral data. ResultsTen phenylethanoid glycosides were isolated and identified as clerodendronoside (1), acteoside (2), isoacteoside (3), cistanoside C (4), jionoside C (5), leucosceptoside A (6), cistanoside D (7), campneoside I (8), campneoside II (9), cistanoside F (10). ConclusionCompound 1 is a new phenylethanoid glycoside, while compounds 4-10 are obtained from this plant for the first time.
