Abstract
The chemical constituents of Vaccinium bracteatum were studied by means of macroporous resin, ODS column chromatography and preparative HPLC. Eleven compounds were isolated from this plant. By using ESI-MS and NMR, the structures of the eleven compounds were determined as 10-O-trans-p-coumaroyl-6alpha-hydroxyl-dihydromonotropein (1), 10-O-cis-p-coumaroyl -6alpha-hydroxyl-dihydromonotropein (2), vaccinoside (3), 10-O-cis-p-coumaroyl monotropein (4), isolariciresinol-9-O-beta-D-xyloside (5), tectoridin (6), vicenin-3 (7), quercetin-3-O-alpha-L-rhamnoside (8), quercetin-3-O-alpha-L-arabinopyranoside (9), quercetin-3-O-beta-D-galactopyranoside (10), and quercetin-3-O-beta-D-glucuronide (11), respectively. Compounds 1 and 2 are new, and compounds 4, 6 and 7 are isolated from the genus Vaccinium for the first time.
采用大孔树脂法、ODS柱层析法和制备高效液相色谱法研究了苞片苗的化学成分。从该植物中分离得到11个化合物。通过ESI-MS和NMR鉴定了这11个化合物的结构，分别为10- o -反式-对香豆醇-6 -羟基-二氢单troppein(1)、10- o -顺式-对香豆醇-6 -羟基-二氢单troppein(2)、疫苗苷(3)、10- o -顺式-对香豆醇单troppein(4)、异核桃树脂-9- o - β -d -木糖苷(5)、鸢尾苷(6)、vicenin-3(7)、槲皮素-3- o - l-鼠李糖苷(8)、槲皮素-3- o - α - l-阿拉伯吡喃苷(9)、槲皮素-3- o - β -d -半乳糖苷(10)、槲皮素-3- o - β -d -半乳糖苷(10)、和槲皮素-3- o - β - d -葡糖苷(11)。其中化合物1、2为新化合物，化合物4、6、7为首次从该属植物中分离得到。
