芳香石豆兰(Bulbophyllum ambrosia),是兰科(Orchidaceae)石豆兰属(Bulbophyllum)植物,生于海拔达
1 300 m的山地林中树干上.分布于福建东部和南部、广东西部、海南、香港、广西西部、云南东南部至南
部[1].国外也分布于越南,具有清热、止咳的作用,传统中医主要用于治疗肺热咳嗽[2].石豆兰属植物中含
有大量的菲、二氢菲、联苄和苯丙素类化合物[3],具有抗肿瘤、抗氧化和抗病毒等多种生物活性[4-6].目前
对芳香石豆兰的化学成分研究还未见报道,本文首次对芳香石豆兰的化学成分进行了研究,从中分离鉴定
了 13个化合物(图 1):moscatin(1) ,3 7-dihydroxy-2,4-dimethoxyphenanthrene(2) ,2 7-dihydroxy-3,4-
dimethoxy- phenanthrene(3) ,2 5-dihydroxy-4-methoxy-9,10-dihydrophenanthrene(4) ,ephemeranthol-A

2 提取分离
干燥的芳香石豆兰样品 5.8 kg,粉碎后用重蒸工业甲醇回流提取 3 次,合并提取液,减压蒸馏回收甲
醇,再加适量水分散,过滤,再用等体积石油醚萃取 3 次,得石油醚部分浸膏 89 g.剩余水部分过大孔树脂
划成两段:水部分(去除)和甲醇部分(70 g).用氯仿 /甲醇体系对甲醇部分进行硅胶柱层析,梯度洗脱,划
成 9 ∶ 1(体积比,下同)洗脱部分(25 g),3:1洗脱部分(32 g)和甲醇洗脱部分(10 g).9 ∶ 1 洗脱部分再用

4 结果与讨论
目前,国内外学者对石豆兰属植物的化学成分研究主要集中在以下 18 个种:线瓣石豆兰(B.gymno-
pus),阔鞘石豆兰(B.vaginatum),伏生石豆兰(B.reptans),B.leopardium,B.protrcatum,密花石豆兰(B.odora-
tissimum),球茎石豆兰(B.triste),广东石豆兰(B.kwangtungense),麦斛(B.inconspicuum Maxim.),B.rigidum,
直葶石豆兰(B.suavissimum Rolfe),匍茎卷瓣兰(B.emarginatum),B.fuscopurpureum,钻齿卷瓣兰(B.guttula-
tum),B.cheiri,B.weddelli,B. Ipanemense,B. involtum.从中共分离鉴定了约 105 个化合物,化合物主要为菲
类、联苄、苯丙素、黄酮、嗯庚英、苷等结构类型,其中以菲类(约 54 个)、联苄类(14 个)、苯丙素类(14 个)
为主要成分.文献报道菲类、联苄类和苯丙素类化合物具有良好的抗肿瘤、抗氧化和抗病毒等多种生物活
性.
本文从芳香石豆兰中分离鉴定了 13个化合物,其中 3 个菲类化合物,6 个二氢菲类化合物,4 个联苄
类化合物.化合物 5,6,7和 9首次从石豆兰属植物分离得到.表明芳香石豆兰具有很好的药用前景,值得进
一步开发研究.

Abstract:The chemical constituents of Bulbophyllum ambrosia were studied and 13 compounds were isolated
by the method of silica gel and Sephadex LH- 20 column chromatography. Their structures were identified as
moscatin (1),3,7-dihydroxy-2,4-dimethoxyphenanthrene (2) ,2 7-dihydroxy-3,4-dimethoxy-phenanthrene
(3) ,2 5-dihydroxy-4-methoxy-9,10-dihydrophenanthrene (4) ,ephemeranthol-A (5) ,3,7-dihydroxy-2,4
-dimethoxy-9,10-dihydrophenanthrene (6) ,2 4-dihydroxy-7-methoxy-9,10-dihydrophenanthrene (7) ,coe-
lonin (8) ,rotundatin (9) ,4,5 -dihydroxyl - 3,3 - dimethoxybibenzyl (10) ,moscatilin (11) ,batatasin Ⅲ
(12) ,and tristin (13)on the basis of spectral analysis.Among them,compounds 5,6,7 and 9 were isolated from
Bulbophyllum for the first time.
Key words:Bulbophyllum ambrosia;phenanthrene;dihydrophenanthrene;bibenzyl;chemical component
