中文摘要 | 高氏桑寄生為桑寄生科植物,由其葉部之甲醇萃取物中分離到八種類黃酮類成分, 從各成分之物理性質及光譜數據確認其結構分別為:(+)-和(-)-catechin之混合物(1), (-)-epi-catechin(2),2',4',6'-trihydroxydihydrochalcone 4'-O-β-D-glucoside(3), pinocembrin 7-O-β-D-glucoside(4),kaempferol 3-O-α-D-rhamnoside(5),kaempferol 3,7-di-O-β-D-glucosdi(6),quercetin 3-O-α-D-rhamnoside(7)及quercetin 3-O-β- D-glucoside(8)。化合物3之光譜數據為首次提出。 |
英文摘要 | In continuing a chemical examination of Loranthaceous plants, this study isolated eight flavonoids from the fresh leaves of Loranthus kaoi, an endemic parasitic shrub found only at median altitudes in the central part of Taiwan. These compounds were a mixture of (+)- and (-)-catechin(1), (-)-epi-catechin(2), 2',4',6'-trihydroxydihydrochalcone 4'-O-β-D-glucoside(3), pinocembrin 7-O-β- D-glucoside(4),kaempferol 3-O-α-D-rhamnoside(5), kaempferol 3,7-di-O-β-D- glucosdi(6),quercetin 3-O-α-D-rhamnoside(7) 及quercetin 3-O-β-D-glucoside(8). The structures of compounds 1-8 were established on the basis of their physical properties and spectroscopic evidence. idence. |
