Phytochemical investigation of the methanol extract of Vitex limonifolia leaves led to the
isolation of three new labdane-type diterpenoids, vitexlimolides A–C (1–3) and eight known
compounds, 5, 4′-dihydroxy-3, 7-dimethoxyflavone (4), vitecetin (5), 5, 4′-dihydroxy-7,
3′-dimethoxyflavone (6), verrucosin (7), 2 α, 3 α-dihydroxy-urs-12-en-28-oic acid (8),
euscaphlic acid (9), 18, 19-seco, 2 α, 3 α-dihydroxy-19-oxo-urs-11, 13 (18)-dien-28-oic acid
(10), and maslinic acid (11). Their chemical structures were elucidated by physical and …
