中文摘要 | 臺灣白及(Bletilla formosana (Hayata) Schltr.) 為多年生臺灣原生蘭科植物,假球莖乾燥可視為白及(Bletilla striata)藥材使用。臺灣白及人工授粉後10週之種子進行無菌播種,5~6 個月後移植出瓶,2007 年3月於田間栽植,2008 年5月植株開花率達55.6% (90/162) ,最大假球莖之直徑可達40.1 mm ,直徑25~30 mm 假球莖平均鮮重為154.6 ± 5.8 mg 。2009 年4~5 月間植株開花率可達80.5% (124/154) ,植株生長強壯,花朵呈粉紅色,部份花莖可形成3~4 支側花莖。臺灣白及假球莖進行化學成分分離與分析,共分離、鑑定得到七個主要化合物,經各種光譜資料解析及文獻資料比對,確認其化學結構分別為militarin (1)、formoside (2)、gymnoside IX (3)、benzyl alcohol (4)、trans-coumaric acid methyl ester (5)、coelonin (6) 和 batatasin III (7),其中formoside (2) 為新化合物。 |
英文摘要 | Bletilla formosana (Hayata) Schltr., a perennial herb orchid native in Taiwan, produced pseudobulbs as the traditional Chinese medicine. Ten-week-old seeds were sown in vitro and the plantlets were subcultured every two months. The plantlets were then transplanted and grown in the greenhouse after 5-6 month culturing. The percentage of flowering was 55.6% and 80.5% in 2008 and 2009, respectively. The diameter of the biggest pseudobulb was 40.1 mm, and the average fresh weight of pseudobulbs in diameter of 25-30 mm was 154.6±5.8 mg. Seven compounds, militarin (1), formoside (2), gymnoside IX (3), benzyl alcohol (4), trans-coumaric acid methyl ester (5), coelonin (6), and batatasin III (7) were isolated and identified from the pseudobulbs, and among them, formoside is a novel compound. |
