| 从铁皮石斛 (Dendrobium officinale) 叶的乙醇提取物中分离得到 12 个化合物。通过光谱数据分
析，分别鉴定为：4- 羟基苯乙酮 (1)、对羟基苯甲醛 (2)、丁香醛 (3)、α- 萘酚 (4)、香草酸 -4-O-β-D- 吡喃葡
萄糖苷 (5)、5- 羟甲基糠醛 (6)、 (3S,5R,6R,7E,9S)-3,5,6,9-tetrahydroxy-7-megastigmene (7)、(6R,9S)-9-hydroxymegastigma-4,7-dien-3-one-9-O-β-D- glucopyranoside (8)、 (3R,9R )-9-O-β-D-glucopyranosyl-3-hydroxy-7,8-
didehydro-β-ionol (9)、cyclomargenol (10)、N-p- 香豆酰酪胺 (11)、肌苷 (inosine, 12)。化合物 4、5、7、8、 9、10 为首次从石斛属中分离获得，化合物 1、2、6、12 为首次自铁皮石斛植物中分离得到。 |

| Abstract: |
| Twelve compounds were isolated from the 95% ethanol extract of the leaves of Dendrobium
officinale. On the basis of spectral data, their structures were identified as 4-hydroxy acetopenone (1), p-hydroxy
benzaldehyde (2), syringaldehyde (3), α-naphthalenol (4), vanillic acid-4-O-β-D-glucopyranoside (5),
5-hydroxymethyl furfural (6), (3S,5R,6R,7E,9S)-3,5,6,9-tetrahydroxy-7-megastigmene (7), (6R,9S)-9-hydroxymegastigma-4,7-dien-3-one-9-O-β-D-glucopyranoside (8), (3R,9R)-9-O-β-D-glucopyranosyl-3-hydroxy-7,8-
didehydro-β-ionol (9), cyclomargenol (10), N-p-coumaroyltyramine (11), inosine (12). Of these compounds, 1、 2、6、12 were isolated for the first time from this herb, and 4、5、7、8、9、10 were isolated for the first time
from Dendrobium genus. |
