[Evaluation for druggability of traditional Chinese medicine preparations in medical institutions based on human use experience].

Traditional Chinese medicine(TCM) preparations in medical institutions are an important source of research and development(R&D) of TCM new drug. With years of usage in therapy, these preparations' safety and effectiveness have generally been validated in clinic. However, there are still a few disadvantages in TCM new medicine development, such as similar prescriptions, excessive prescription ingredients, too broad clinical orientation, lack of solid clinical data, issue in pharmaceutical quality control, and intellectual property disputes.

Modified Abietane Diterpenoids from Whole Plants of Selaginella moellendorffii.

A new modified abietane diterpenoid, (3S,4S,5R,10S)-18(4→3)-abeo-3,4,12,18-tetrahydroxy-8,11,13-abietatrien-7-one (1), and two novel dimers, selaginedorffones A (2) and B (3), featuring a new cyclohexene moiety that was biogenetically constructed from two modified abietane diterpenoids through a Diels-Alder reaction were obtained from a methanolic extract of Selaginella moellendorffii, a traditional Chinese herb. The structures of 1-3 were identified by a combination of NMR spectroscopic analysis and ECD calculations. In the present study, diterpenoids were identified from S.

Neolignans from Selaginella moellendorffii.

Two new neolignans selaginellol (1) and selaginellol 4'-O-β-D-glucopyranoside (2), together with seven known compounds (3-9), were isolated from the whole plant of Selaginella moellendorffii. The structures of the new isolates were determined through spectroscopic data analysis. Compounds 1-9, as well as compounds 10-18 previously isolated from the species, were measured for the activity against platelet aggregation induced by ADP or collagen.

Ethnobotany of wild plants used for starting fermented beverages in Shui communities of southwest China.

Background: Shui communities of southwest China have an extensive history of using wild plants as starters (Xiaoqu) to prepare fermented beverages that serve important roles in interpersonal relationships and cultural events. While the practice of using wild plants as starters for the preparation of fermented beverages was once prevalent throughout China, this tradition has seen a decline nationally since the 1930s. The traditional technique of preparing fermented beverages from wild plant starters remains well preserved in the Shui communities in southwest China and provides insight on local human-environment interactions and conservation of plant biodiversity for cultural purposes.

Ethnobotanical study on wild plants used by Lhoba people in Milin County, Tibet.

Background: The Lhoba are a small ethnic group, located in the Tibet Autonomous Region of China. Until 1960, their livelihood was predominantly based on swidden agriculture, hunting, and gathering. To investigate and document the plant species used by the Lhoba, ethnobotanical surveys were conducted in three villages of Nanyi Township in Milin County, Tibet, China.

Seeds used for Bodhi beads in China.

Background: Bodhi beads are a Buddhist prayer item made from seeds. Bodhi beads have a large and emerging market in China, and demand for the beads has particularly increased in Buddhism regions, especially Tibet. Many people have started to focus on and collect Bodhi beads and to develop a Bodhi bead culture.

Eating from the wild: diversity of wild edible plants used by Tibetans in Shangri-la region, Yunnan, China.

Background: Locally harvested wild edible plants (WEPs) provide food as well as cash income for indigenous people and are of great importance in ensuring global food security. Some also play a significant role in maintaining the productivity and stability of traditional agro-ecosystems. Shangri-la region of Yunnan Province, SW China, is regarded as a biodiversity hotspot.
