A new ecdysteroid, 26-hydroxypinnatasterone (1), together with 20-hydroxyecdysone, was isolated from the stem barks of Vitex cymosa. 20-Hydroxyecdysone, ajugasterone C, ajugasterone C monoacetonide and turkesterone were isolated from the branches of V. polygama. The structure of 1 was determined by
Two new ecdysteroids, 24-epi-pinnatasterone (1) and scabrasterone (2), together with 11 known ecdysteroids, calonysterone, pterosterone, 24-epi-makisterone A, 20-hydroxyecdysone (3), polypodine B, ajugasterone C, pinnatasterone (4), 11alpha-hydroxyecdysone, 24-epi-abutasterone,
