臺灣白及（Bletilla formosana（Hayata）Schltr.）假球莖發育與成分分析
The Development, Cultivation and Chemical Constituents in Psudobulbs of Bletilla Formosana (Hayata) Schltr
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。
並列摘要
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.
