At the surface of the pollen grains there are three types of aperturates, including three porates type, three colpates type and three porate - colpates type ; and four types of sculpture, namely, reticulate, striate, striate - reticulate and verrucate. the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization, and the experimental methods are proved stable. the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other. oieanolic acid, l, 5, 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc, and the different chromatogram of various plants can be considered as characters of identification. the contents of oleanolic acid in 12 species of plants are determinated by hplc, but among the different plants and botanical organs their contents are different, and the highest content in flowers
