采用大孔吸附树脂柱色谱、聚酰胺、Sephadex LH-20柱色谱、高压制备色谱等方法从青皮竹竹叶提取物中分离得到12个化合物,经理化常数测定和波谱学方法分析,鉴定为对羟基苯甲醛(p-Hydroxybenzaldehyde,1)、荭草苷(Orientin,2)、异荭草苷(Isoorientin,3)、牡荆苷(Vitexin,4)、异牡荆苷(Isovitexin,5)、苜蓿素(Tricin,6)、对香豆酸(p-Coumaric acid,7)、异牡荆苷-2“-鼠李糖苷(Isovitexin-2”-rhamnoside,8)、异牡荆苷-2“-木糖苷(Isovitexin-2”-xylopyranoside,9)、芹菜素-6-C-波伊文糖-7-O-葡萄糖苷(Apigenin-6-C-boivinose-7-O-glucopyranose,10)、芹菜素-7-O-葡萄糖苷(Apigenin-7-O-glucopyranos,11)及苜蓿素-4’-O-葡萄糖苷(Tricin-4’-O-glucopyranose,12),其中化合物8、9、10、11、12为首次从该植物中分离获得。本研究结果为青皮竹竹叶的综合利用提供了理论依据,对竹类植物中天然产物的开发利用具有指导意义。
Twelve compounds were isolated from the leaves of M.cerevisiae by macroporous adsorption resin column chromatography, polyamide, Sephadex LH-20 column chromatography and high pressure preparative chromatography. Their chemical constants and spectral analysis were used to identify the compounds P-Hydroxybenzaldehyde, Orientin, Isoorientin, Vitexin, Isovitexin, Tricin (6), p-Coumaric acid (7), isovitexin-2 “-rhamnoside (8) Isovitexin-2 ”-xylopyranoside (9), Apigenin-6-C-boivinose-7-O-glucopyranose ), Apigenin-7-O-glucopyranos (11) and Tricin-4’-O-glucopyranose (12) 9,10,11,12 for the first time isolated from the plant. The results of this study provide a theoretical basis for the comprehensive utilization of bamboo leaves of bamboo, and have guiding significance for the development and utilization of natural products in bamboo plants.
