野生东北刺人参的X射线衍射研究

X-ray Diffraction of Tall Oplopanax (Oplopanax elatus)

为揭示东北刺人参根、茎、叶、果的Ｘ射线衍射特征，应用粉末Ｘ射线衍射的方法，获得该植物上述４个部位的Ｘ射线衍射图谱和数据。结果表明：东北刺人参４个部位的Ｘ射线衍射图谱可用于该药材的鉴定。经对比分析确认东北刺人参根与茎具有相同的Ｘ射线衍射数据，为以茎代根利用东北刺人参提供了谱学依据。

The root of Oplopanax elatus Nakai (Araliaceae) is a folk medicine bellyed to possess similar pharmacological actions as Panax ginseng in supplementing'Qi' and strengthening'Yang'. In order to ascertain whether the stem, leaf and fruit of the plant may also be used for the same therapeutic purpose, their powder X-ray diffraction patterns (XDP) were compared. Results showed that the XDPs of root and stem were very similar, proving that they may be used alternatively, and moreover, these XDPs including that of leaf and fruit may be used as criteria for the identification of the plant.
