Chemical, pharmacologial and quality control studies of traditional chinese medicine (TCM) and ethnic medicine

Twenty-four new compounds were isolated from Kadsura heteroclita, an anti-arthritic Tujia ethnomedicine called “Xue Tong”. Eight new xanthone glycosides including three potent neuroprotective compounds were isolated from Swertia punicea, named as “Gan Yang Cao” in the folk of Southwest China. Six compounds from n-BuOH extract of this plant displayed herbicidal activity against dicot Lactuca sativa (lettuce) and monocot Agrostis stolonifera (bentgrass). Four antifungal coumarins were obtained from TCM plant Angelica dahurica showed potential biopesticide activity. Moreover, marine shelled TCM Concha Arcae quality control studies in 2015 Chinese pharmacopoeia, Typhane Pollen and Magnoliae Flos quality control studies in European Pharmacopoeia were performed, as well as qualitative and quantitative determination of Liuwei Dihuang preparations by multi-marker components and UHPLC dual-wavelengths fingerprint mode.
