In this paper, twenty-two compounds including twenty-one flavonoids (1-21) and one alkaloid (22) were isolated from Panzeria alaschanica, in which seventeen flavonoids (1-2, 5-11, 13-20) were isolated from P. alaschanica and four flavonoid p-coumaroylglucosides (15-18) from the genus Panzeria for the first time. The occurrence of flavonoid p-coumaroylglucosides and alkaloids might be employed as the common characteristic constituents of the genera Panzeria, Leonurus, Lagochilus, Lagopsis and Marrubium. © 2015 Published by Elsevier Ltd.

Phytochemical investigation of Gentianella turkestanorum (Gentianaceae) afforded nineteen compounds, including six xanthones (1-6), two triterpenoids (7-8), eight flavones (9-16) and three iridoids (17-19). Here, we firstly reported that 1-hydroxy-3,5-dimethoxyxanthone (4), 1, 8-dihydroxy-3-methoxyxanthone (5), apigenin (9), quercetin (10), luteolin-7-O-glucoside (12) and three other compounds (1, 8-dihydroxy-3-methoxyxanthone (5), apigenin-7-O-gluco (1″ → 3‴) glucoside (15) and luteolin-7-O-gluco (1″ → 3‴) glucoside (16)) could be isolated from G. turkestanorum. The occurrence of chemical data and the sequence data might be employed as common constituents of the genera Gentianella, Lomatogonium and Swertia. © 2016 Elsevier Ltd.
