The floral essential oil composition and biological activity of Solanum macranthum Dunal

Abstract

The essential oil from the floral part of Solanum macranthum Dunal was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of seventeen compounds were identified representing 100% of the oil composition. Major components of the volatile oil were pentadecane (58.6%), (E)-nerolidol (15.4%), a-phellandrene (7.5%) and (E)-nerolidol acetate (5.6%). The essential oil exhibited strong antimicrobial activity (39-625 μg/ml) on pathogens employed in the assay. However, no appreciable cytotoxic effects on human breast carcinoma cells (Hs 578T) and human prostate carcinoma cells (PC-3) were observed. The fl
