ABSTRACT

Magnolia tiepii V. T. Tran & N. V. Duy sp. nov. (Magnoliaceae) is recognized from southern Vietnam, where it occurs in Khanh Vinh slope, Khanh Vinh District, Khanh Hoa Province. Four flavonoid glycosides were isolated from the leaves of Magnolia tiepii, including kaempferol 3-neohesperidoside (1), kaempferol 3-O-α-L -rhamnopyranosyl-(1→2)--D-galactopyranoside (2), quercetin 3-neohesperidoside (3), and quercetin 3-O-α-L-rhamnopyranosyl-(1→2)--D-galactopyranoside (4). Their chemical structures were elucidated by spectrocopic NMR, MS, and IR analysis as well as comparing their data with the ones in the literature. Although these compounds were known in other plants but this is the first time they are reported in this species.

Keywords: Magnolia tiepii, kaempferol, quercetin, flavonoid glycoside.
