| 摘要: |
| 该研究利用大孔吸附树脂D101、MCI树脂、正相硅胶、ODS、Sephadex LH-20和反相HPLC等多种色谱分离方法,对红根草95%乙醇提取物的乙酸乙酯萃取部位进行了分离。结果表明:通过分离共得到了10个化合物,经波谱数据分析鉴定为3-表-白桦脂酸(1)、白桦脂醇(2)、齐墩果酸(3)、3β, 6β, 23-三羟基-12-烯-28-齐墩果酸(4)、高根二醇(5)、2α, 3β, 23-三羟基-12-烯-28-乌苏酸(6)、2α, 3β, 19α-三羟基-12-烯-28-乌苏酸(7)、2α, 3α, 24-三羟基-12-烯-28-乌苏酸(8)、2α, 3α, 24-三羟基-12, 20(30)-二烯-28-乌苏酸(9)、山奈酚-3-O-葡萄糖苷(10)。其中,化合物1为首次从鼠尾草属植物中分离得到,化合物2、4、5、6、7、8、9、10为首次从该植物中分离得到。 |

| Abstract: |
| From a 95% ethanol extract of Salvia prionitis, ten compounds were isolated by means of various chromatographic techniques including column chromatography over macroporous resin D101, MCI gel, silica gel, ODS, Sephadex LH-20, and reversed-phase HPLC. Their structures were elucidated using spectroscopic data as 3-epi-betulinic acid(1), betulin(2), oleanic acid(3), 3β, 6β, 23-trihydroxyolean-12-en-28-oic acid(4), erythrodiol(5), 2α, 3β, 23-trihydroxyurs-12-en-28-oic acid(6), 2α, 3β, 19α-trihydroxyurs-12-en-28-oic acid(7), 2α, 3α, 24-trihydroxyurs-12-en-28-oic acid(8), 2α, 3α, 24-trihydroxyurs-12, 20(30)-dien-28-oic acid(9), and kaempferol-3-O-glucoside(10). Compound 1 was obtained from the genus of Salvia for the first time, and compounds 2, 4, 5, 6, 7, 8, 9, 10 were obtained from this plant for the first time. |
