Research Personnel Leader:
Dr. Rosalinda C. Torres

Research Duration Start:
16 April 2012
15 April 2014
Research Location DOST-ITDI
Research Description (1) To undertake crude extraction and extract essential oils from some Philippine medicinal plants; (2) To determine the larvicidal activity of the crude extracts and essential oils; (3) To undertake phytochemical screening of the crude extract; (4) To conduct polarity-based fractionation of the crude extracts and determine larvicidal efficacy of the fractions; (5) To isolate and characterize further the most active fraction of the plant which exhibited the most significant activity; (6) To analyze the essential oils for physico-chemical properties and chemical composition bychromatographic methods; (7) To develop larvicidal product(s) that can be field tested on a wider scale; (8) To conduct product analysis and shelf-life/stability testing; (9) To conduct field trial testing of the products.
