Varieties textual research, resource investigation and identification of commercial drugs on Cuscutae Semen / 中国中药杂志

Through the textual research, resource investigation, literature reviews (including Flora of China, municipal Flora, pharmacopoeia of China and municipal drug standards) and identification of commercial drugs on Cuscutae Semen, it was found the species described in the herbal textual was Cuscuta chinensis, with good quality from Shandong and Henan Province. The identification of commodities showed the majority drugs were from C. australis, varied from the ancient herbal textuals .Mordern literature reviews indicate that it was necessary to strengthen the research on Cuscutae Semen from C. australis, C. chinensis and C. japonica because of their differences in resources, macroscopical and microscopical characters, while wrong descriptions in some literatures. It was suggested that the two species (C. australis and C. chinensis) should be separated in pharmacopoeia of China. The study provides scientific basis for the development and utilization of Cuscutae Semen.

Histomorphological study on folk medicine Lysimachia fortunei / 中国中药杂志

To set standards for histomorphological studies on Lysimachia fortunei, an efficacious and widely applied folk medicine in this study, in order to develop its resources. Its species were identified by observing plant morphology and herbs appearance characters, preparing slices with routine methods and defining structural characters. According to the results of morphologic observation, leaves, stamen and pistil of this plant were different from the descriptions in Flora of China. The whole herb can be used in medicines, mainly including rhizomes, stems and leaves. According to the findings in the first study on microscopic structures, its rhizomes, stems and leaves were characteristic and worth identifying. The transaction tissue structures of rhizomes and stems were under developed and contained endodermis, secretory structures; Stems had sclerenchymata of different shapes of sclereids; Leaves were bifacial and had vascular bundles under midribs, which were surrounded by parenchymal sheathes. On the surface of leaves, stomata, glandular hairs and keratin lines were morphologically different in upper and lower epidermis. The herbal power had glandular hairs, sclereids and vessels. In conclusion, herbs of L. fortunei can be identified by the above histomorphological characteristics, which lays a foundation for further development and application of L. fortunei.
