Traditionally, the leaves of are decocted and used by Chinese Mongolians, Koreans, and Tibetans to treat skin itching, dry cracks, and other skin ailments, which indicates leaves may have a potential inhibitory effect on various skin inflammations. To examine the protective effect against skin inflammations of leaf extract (ATLE), an dermatitis model was established using sodium dodecyl sulfate (SLS)-induced HaCaT cells.

Ethnobotanical study on herbal tea drinks in Guangxi, China.

Background: Herbal tea drinks, different from classical Camellia beverages, are a wide variety of herbal drinks consumed for therapeutic purposes or health promotion. Herbal tea is widely consumed in Guangxi. However, the documentation on the plants for herbal tea and their related health benefits is still limited.

UPLC-QTOF-MS-based metabolomics and chemometrics studies of geographically diverse Acer truncatum leaves: A traditional herbal tea in Northern China.

Traditionally in Northern China, Acer truncatum leaves (ATL) have been used as herbal tea, now consumed worldwide. Few studies have reported ATL metabolites from different areas and their correlation with the environment. Thus, metabolomic analyses were conducted on ATL collected from twelve locations throughout four environmental zones in Northern China to understand the phytochemical differences with regards to environmental conditions.

Metabolic profiling, spatial distribution, and biosynthetic pathway of functional metabolites in stem revealed by combining UPLC-QTOF-MS with MALDI-TOF-MSI.

The stem of Lindl. (Orchidaceae), called "" in traditional Chinese medicine, is a well-known medicinal and edible plant material in China. It is used as an antipyretic, analgesic, and tonic to nourish the stomach and (i.
