Biopharmaceutical Identification of Adventitious Buds and Root Bark of Aralia elata Seem.

摘要

[Objectives]This article aimed to systematically study the biopharmaceutical characteristics of root bark and adventitious buds(tender stems and young leaves)of Aralia elata Seem.and to distinguish its root bark from that of Acanthopanax gracilistylus,in order to avoid confusion in clinical medication and guide root segment cutting technology of A.elata Seem.[Methods]Samples were obtained by field collection,and using trait and microstructure identification techniques,systematic biopharmaceutical identification of samples was carried out.[Results]The trait and microscopic characteristics of the root bark and adventitious buds(tender stems and young leaves)of A.elata Seem.were clarified.[Conclusions]The traits,cross-sections and powder of root bark,tender stems and young leaves of A.elata Seem.all have unique identification characteristics.The secondary phloem of A.elata Seem.is particularly developed,and it provides adventitious buds with sufficient nutrients for their meristem.
