Mp. Calcagno et al., ACETYLATED ECDYSTEROIDS FROM AJUGA-REPTANS VAR ATROPURPUREA (LAMIALES, LAMIACEAE), European journal of entomology, 92(1), 1995, pp. 287-293
The structural elucidation of acetylated ecdysteroids isolated from dr
ied roots of Ajuga reptans var. atropurpurea, based on spectroscopic p
rocedures, is reported. Among them 2-O-acetyl- and 3-O-acetyl-20-hydro
xyecdysone (20E2Ac, 20E3Ac) and 3-O-acetyl-29-norcyasterone (29NCY3Ac)
had previously been only partially described and 3-O-acetylcyasterone
(CY3Ac) was heretofore unreported.
