EXTRACTION AND BIOACTIVITY FROM JATROPHA CURCAS L. LEAVES BY STEAM DISTILLATION
Laura Soto-Armenta
Abstract
Jatropha curcas L. is a plant that has been shown to have biological activities that can contribute to find new products. In this study, steam distillation at laboratory scale was applied to J. curcas leaves to assess the yield of essential oil and the bioactivity of the hydrolate. The effect of steam flow and bed porosity on the extraction yield were also determined. The extracts were analyzed by GC-MS. Dibutyl phthalate, phytol, and diisooctyl phthalate were the majoritarian components. The greatest yield obtained was 0.38% on a dry weight basis. The bioassays showed that the hydrolate of J. curcas possess toxicity against Spodoptera littoralis, Myzus persicae, Lactuca sativa, and Lolium perenne.
