OBJECTIVE:To improve the quality standard of Sida rhombifolia. METHODS: The microscopic structure of Sida rhombifolia was identified. RESULTS: The fiber bundles in circular permutation were apparent in bark area of the transverse section in stem and root. The main vein of the leaf assumed sulciform and the palisade tissues were in 2 tiers.There were large stellate hair,small bulb-shaped glandular hair,vase-shaped glandular hair and calcium oxalate cluster crystal in the powder.CONCLUSION: The experimental results serve as references for the identification and the establishment of the related quality standard for Sida rhombifolia.

OBJECTIVE:To study the microscopic TLC characteristics of Fritillaria thunbergii,Bulbus Fritillariae Cirrhosae,Fritillaria hupehensis,Fritillaria ussuriensis and Bulbus Fritillariae Pollidiflorae.METHODS: The five kinds of Fritillaria(powder)was identified microscopically in accordance with Chinese Pharmacopeia,and two development systems were applied for the TCL identification of the five kinds of Fritillaria.RESULTS: The microscopic characteristics of the 5 kinds of Fritillaria were obtained.Both peimine and peiminine were noted in the TLC of Fritillaria thanbergii,Bulbus Fritillariae Cirrhosae,Fritillaria hupehensis and Fritillaria ussuriensis,but were not noted in the TLC of Bulbus Fritillariae Pollidiflorae,however,imperialine was noted in the TLC of Bulbus Fritillariae Pollidiflorae.CONCLUSION: The results serve as basis for the identification of 5 kinds of Fritillaria.

OBJECTIVE: To identify the pharmacognosy of Canscora lucidissima. METHODS: The morphologic feature, property and microscopic features of the original C. lucidissima were identified. RESULTS: The stem of the C. lucidissima was found to be ramous, hollow and light yellowish-brown, and most of the leaves were intermingled with stems. Microscopically, the exodermises cells and the endodermis cells of the root were large, which were more often radially divided into multi-daughter cells, and stone cells were noted occasionally; the stem was hollow and bicollateral and crevasse was seen in cortex; inequality stoma were seen on both the upper epidermis and lower epidermis of the leaves; sandy crystal, small acicular crystal and prism, etc were often seen in the cells. CONCLUSION: The above features serve as references for the identification of C. lucidissima.
