ABSTRACT
OBJECTIVE: To provide fundamental information for its exploiting. Aralia echinocaulis by the resource and identification study on. METHOD: Resource survey and various identification were carried out. RESULT: The county level distribution and ecological environment of A. echinocaulis were initially observed. It mainly distributed in the mountainous areas of the Yangtze River basin and the south, and was usually used as folk drug. This study also displayed its morphological, microscopic and chemophysical identification features. CONCLUSION: The morphological features of original plant and crude drug, and the anatomical and chemophysical characteristics of A. echinocaulis are of identification value, and the species are also of greater development and utilization potentiality, but the resource does not support the sustainable utilization. Therefore, artificial propagation is apparently crucial to its exploitation.

OBJECTIVE: To make clear the descriptions and microscopic histological structures of the roots, stems and rootstocks for twelve species from Aralia plants. METHODS: Observing the descriptions and histological characteristics. RESULT: The histological characteristics of the various species are basically identical. Each of them equally contains cluster crystals of calcium oxalate and starch grains; secretory canals exist extensively in the cortexes, phloem and piths; neither cortexes nor phloem of roots have thick-walled cells, but cortexes and phloem of the stems of the wood plants have fibers or stone cells. CONCLUSION: The pharmacognostic and interspecies characteristics for wood and herbaceous plants identification were obtained. The wood and herbaceous plants in one natural group of a genus as its two subgenera was sustained by the study result.

This paper reported the studies on morphological and histological diagnostic characteristics and powder feature the root of Aralia decaisneana Hance. Chemical analysis indicates essential oil from root cortex contains at least 16 constituents which trans-caryophllene, 9,12-octadecaienoic acid, etc. are the major ingredients.

OBJECTIVE: To Study the identification of medicinal and edible tender shoots of Aralia in China. METHODS: Morphological identification and differential thermal analysis(DTA). RESULTS: Important morphological and DTA features for identification were found. CONCLUSION: It is difficult to identify these tender shoots merely on morphological characteristics, but the combination of morphological features with distinctive aspects of DTA curve helps distinguish these species and give an identification index.
