About the Cover

Averrhoa carambola is one of the ornamental plants that are becoming increasingly popular because of its medicinal properties. This study assesses the bioactive components of Averrhoa carambola ethanol leaf and fruit extracts using Gas Chromatography-Mass Spectrometer. Acute toxicity study was also carried out on wistar strain albino mice using standard procedures. The varying doses of the extracts were administered orally to the male wistar albino mice and signs accompanying toxicity and possible death of animals were monitored. Eight bioactive phyto components were identified in the GCMS analysis of Averrhoacarambola ethanol leaf extract, with Bis (2-ethylhexyl) phthalate having the highest percentage concentrations (24.31%) quantitatively. The ethanol fruit extract had six bioactive components identified, with citral having the highest concentration of 20.59%. Acute toxicity studies revealed the ethanol leaf extract had a median lethal dose (LD50) value of 3605.55mg/kg body weight. Conversely, the ethanol fruit extract of A. carambola showed no lethal signs of morbidity and mortality even at doses up to 5000mg/kg body weight.
