Abstract
A limonoid was isolated and characterized from the chloroform extract of the calamansi [xCitrofortunella microcarpa (Bunge) Wijnands] seeds. The maximum wavelength of absorption of the limonoid isolate was 244 nm and has a melting point of 208-212 C. The spectral data (FT-IR and H-NMR) suggest that the limonoid isolate were that of calamin, methyl deacetylnomilinate and 6-keto-7B-deacetylnomilol, which were found naturally occuring in calamondin seeds. Calamin was the most probable structure of the isolated limonoid since it has a melting point (208 celcius) which is within the range of that of the obtained compound. Some of the chemical shifts obtained from the H-NMR spectrum of the isolate was identical with that of calamin.
