摘要
目的研究石崖茶Adinandra nitida的化学成分。方法运用色谱方法分离纯化,经波谱数据和理化性质鉴定化合物结构。结果从石崖茶的甲醇提取物中分离鉴定13个萜类化合物,包括11个三萜:乌索酸(1)、18-羟基乌索酸(2)、2α,3α-二羟基乌苏酸(3)、3α,19α-二羟基乌苏酸(4)、蔷薇酸(5)、3β,19α,23-三羟基酸(6)、2α,3α-二羟基乌苏酸-28-O-β-D-葡萄糖苷(7)、kajiichigaside F1(8)、齐墩果酸(9)、arjunetin(10)、白桦脂酸(11),2个二萜:cassipourol(12)、α-生育酚(13)及2个甾体化合物:胡萝卜苷(14)、β-谷甾醇(15)。结论化合物1~4、6、7、9、11~13为首次从石崖茶中分离得到。
Objective To study the chemical constituents from the leaves of Adinandra nitida. Methods The chemical constituents of the plant were isolated and purified by column chromatography and their structures were elucidated on the basis of physicochemical properties and spectral data. Results Eleven triterpenoids, two diterpenoids, and two steroids were obtained and determined to be ursolic acid(1), 18-hydroxyursolic acid(2), 2 α,3 α-dihydroxyursolic acid(3), 3 α,19 α-dihydroxyursolic acid(4),euscaphic acid(5), 3β,19α,23-trihydroxyursolic acid(6), 2α,3α-dihydroxyursolic acid-28-O-β-D-glucopyranoside(7), kajiichigaside F1(8), oleanolic acid(9), arjunetin(10), betulinic acid(11), cassipourol(12), α-tocopherol(13), daucosterol(14), and β-sitosterol(15). Conclusion Compounds 1—4, 6, 7, 9, and 11—13 are obtained from the leaves of A. nitida for the first time.
