GRAPHICAL ABSTRACT
ABSTRACT
A new lignan, 4,4²-dihydroxy-3,3¢,5¢,3²,5²,7²-pentamethoxy-7,9¢;7¢,9-diepoxy-4¢,8²-oxy-8,8¢-sesquineo-lignan-propanol (1), along with six known lignans (2-7) was isolated from the leaves of Ormosia xylocarpa (Chun ex L. Chen). The structure of compound 1 was elucidated through comprehensive 1D and 2D NMR, UV, IR, and HRMS analyses. Compounds 2~3 performed strong antioxidant activity, the median clearance concentration of DPPH, ABST+, and ·OH was lower than 40 μM.
