本研究由白■木(Aralia binnata)木質部分的甲醇萃取液,經由矽膠管
柱色層分析,再結晶,製備用厚片色層分析等方法,得到九種成份,藉由紫外
光/可見光光譜,紅外線光譜,核磁共振光譜,質譜及高解析度質譜等方法,
鑑定出這些成份如下:化合物A:Amyrin.化合物B: Bis-(2-ethylhexyl)
phthalate.化合物C:Xanthyletin.化合物D: Asarinin. 混合物E: Long
chain fatty acids.混合物F: Phytosterols. 化合物G: Dictamnine化
合物H: Des-N-methylchelerythrine. 化合物I:Skimmianine.在這些化合
物中,Asarinin 在五加科植物成份報告中從未出現。

Nine compounds of the methanolic extract of the woody part of
Aralia bipinnata were seperated by silicagel coloumn
chromatography、recrystalization and preparative thick layer
chromatography. The following compounds were identified:
compound A: ?Amyrin. mixtures E: Long chain fatty acids.
compound B: Bis-(2-ethylhexyl)phthalate. mixtures F:
phytosterol compound C: Xanthyletin. compound G: Dictamine
compound D: Asarinin. compound H: Des-N-methylchelerithrine.
compound I: Skimmianine.
