6 October 2014/Accepted: 9 April 2015 ABSTRACT Chromatographic purification
of chloroform extract of the twigs of Ellipeia
cuneifolia has led to the discovery of three compounds comprising
of 2’,4’-dihydroxy-4,6’-dimethoxychalcone; tepanone; and O-methylmoschatoline.
Structures of the compounds were established by interpreting their
spectral data and by comparing them with those of the literature.
Two of them showed antibacterial activities. Keywords: Annonaceae; antibacterial activity; chalcone; Ellipeia cuneifolia;
oxoaporphine; chalcone; twig ABSTRAK Penulenan kromatografi
terhadap ekstrak kloroform ranting Ellipeia
cuneifolia membawa kepada penemuan 3 sebatian iaitu 2’,4’-dihidroksi-4,6’-dimetoksikalkon;
tepanon; dan O-metilmoskatolina. Struktur sebatian ini telah ditentukan
dengan mentafsirkan data spektrum dan membandingkannya dengan data
spektrum daripada penerbitan. Dua daripadanya menunjukkan aktiviti
antibakteria. Kata kunci: Aktiviti
