摘要:
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。

Abstract:
To study the chemical constituents of the extracts from the leaves of Bambusa textilis McClure, the extracts were isolated by column chromatography on macroporous resin (AB-8), Polyamide, Sephadex LH-20, Prep HPLC, and their structures were elucidated by the analysis of spectral data and physiochemical properties. Twelve compounds were identified as p-Hydroxybenzaldehyde, Orientin, Isoorientin, Vitexin, Isovitexin, Tricin, p-Coumaricacid, Isovitexin-2’’-rhamnoside, Isovitexin-2’’-xylopyranoside, Apigenin-6-C-boivinose-7-O- glucopyranose, Apigenin-7-O-glucopyranos, and Tricin-4’-O-glucopyranose. Compounds 8, 9, 10, 11and 12 are isolated from Bambusa textilis McClure for the first time. The results not only provide a theoretical basis for the utilization of natural product from bamboo plants, but also have guiding significance for comprehensive utilization of bamboo leaves.
Key words:  bamboo leaves  Bambusa textilis McClure  chemical constituents  structural identification
