Phytochemical study on the benzene:acetone extract of the leaves of Artabotrys odoratissimus

Abstract

Artabotrys odoratissimus has been investigated by many workers for its constituents. The compounds so far isolated from the leaves of A. odoratissimus are Pentadecyl-7-hydroxy- dodecanote, Pentadecyltritriacontanonte, 4,5-epoxy -26-ol- dopentacontane, β-Sitosterol, Aplysterol, Nonacosanylhexaconsanoate, Pentatetraacont-19-ol, triacont-2-ol, Dotriacont-7-ene, Octacose-7-ene, 1-hydroxy-2,5-dimethyl-9,10-anthraquinone, 1,4,5-trihydroxy-9,10-anthraquinone, 13-hydroxynonacosane, Nonanoicacid, Methylphenyl propanoate, Decanoicacid, Diethylphthalate, Dibutylphthalate, 2-amino-3-ethylbipheny-l, 5-methyl-9-phenylnonane-3-ol, 1-phenylundecane, 2,5-dimethyl-1-phenylheptane1-one, hexadeca-2,7,11-triene, 1-isopropyl-4,6-dimethylnaphthalene, 1-phenyldeca-1-one, 1-phenylundecan-1-one, 5-(2-butylphenyl)pent-3-en-2-ol, 2,5-dimethyltetradecanhydro phenenthrene So far, not many studies have been carried out on this genus but there are some reports on this plant. Previous phytochemical studies have revealed this genus to be rich in secondary metabolites including phenylcoumarins, xanthones and triterpenoids. Our recent study on the benzene:acetone extract of the leaves of A. odoratissimus, have led to the isolation of steroidal compound. The structure of the compound has been established by modern spectroscopic techniques such as Infrared Spectrometry (IR), Hydrogen-Nuclear Magnetic Resonance Spectrometry (1H-NMR), Carbon-Nuclear Magnetic Resonance Spectrometry (13C-NMR) and Mass-Spectroscopy and identified as 2β- hydroxy- Stigmasta- 4- en-3, 6- dione- Methoxy ester. Key words: Artabotrys odoratissimus, medicinal plant, new compound, spectral analysis.
