從金草蘭莖部分離得到9個化合物,經由光譜分析,鑑定為:coumarin (1),alkyl 4'-hydroxy-trans-cinnamates (2),campesterol (3),stigmasterol (4),β-sitosterol (5),aliphatic alcohols(6),alkyl trans-ferulates (7), stigmast-4-en-3-one (8),及aliphatic acids (9),這些化合物是首次自本植物分離。在這些化合物中,coumarin (1)為正己烷及乙酸乙酯抽出物之主成分。
Nine compounds were isolated from the stems of Dendrobium clavatum var. aurantiacum. On the basis of spectral analysis, they were identified as coumarin (1), alkyl 4'-hydroxy-transcinnamates (2), campesterol (3), stigmasterol (4), β-sitosterol (5), aliphatic alcohols (6), alkyl trans-ferulates (7), stigmast-4-en-3-one (8), and aliphatic acids (9). These compounds were first isolated from this plant. Among them, coumarin (1) is the major component in both n-hexane and ethyl acetate extracts.
