Description / Table of Contents:
Pentanortriterpenoids from Azadirachta indica A. Juss (Meliaceae)Pentanortriterpenoids have been isolated for the first time from seed oil, leaves, and bark of Azadirachta indica. Nimbinene (1a), 6-deacetylnimbinene (1b), nimbandiol (2a), and 6-O-acetylnimbandiol (2b) have been found in the seed oil, 1a, b and 2a in the leaves, 1a and b in the bark. The structure determination was carried out by NMR spectroscopy.
Notes:
Aus Samenöl, Blättern und Rinde von Azadirachta indica A. Juss (Meliaceae) wurden erstmals Pentanortriterpenoide isoliert. Nimbinen (1a), 6-Desacetylnimbinen (1b), Nimbandiol (2a) und 6-O-Acetylnimbandiol (2b) finden sich im Samenöl, 1a, b und 2a in den Blättern, 1a und b in der Rinde. Die Konstitutionen wurden NMR-spektroskopisch zugeordnet.
