Coptis chinensis inflorescence extract protection against ultraviolet-B-induced phototoxicity, and HPLC–MS analysis of its chemical composition
L Zhu, B Huang, X Ban, J He, Y Chen, L Han… - Food and chemical …, 2012 - Elsevier
Cultivated Coptis chinensis inflorescence has been highly valued in Chinese tea production
for many years. The main alkaloid compounds in C. chinensis inflorescence ethanolic
extracts (CE) were identified by high-performance liquid chromatography–mass
spectrometry. The detected compounds included jatrorrhizine (4.87 mg/g), coptisine (17.18
mg/g), palmatine (3.32 mg/g), and berberine (31.81 mg/g), as well as columbamine and
epiberberine (tentatively identified). CE protective activity against ultraviolet-B (UVB) …
