Phytochemical studies on the CHCl3 extract of the fruit pulp of Murraya koenigii afforded three new dimeric
carbazole alkaloids, bisgerayafolines A−C (1−3). Bisgerayafolines A−C (1−3) are structurally unique dimeric carbazole alkaloids
comprising geranyl moieties incorporated in their structures. Compounds 1−3 exhibited various levels of antioxidant, anti-α-
glucosidase, DNA binding, and cytotoxic activities and protein interactions.
