Abstract

Nowadays, the use of natural plant source insecticides in one of the best chosen due to its characteristic, which of safer and easily degradable by nature (biodegradable) compared to synthetic materials. One of plant sources wiich consists of active components for insecticides is neem plant. This study aimed to determine the effect of extraction of active ingredients of neem seeds and leaves by fermentation using Effective Microorganisms (EM4). The Extraction of seed and leaf neem to produce neems active compound was conducted by using Effective Microorganisms. The efficacy test of the neem seed and leaf was conducted by using fermented extract concentrated of 3% and 6% and observed with interval of 2 to 6 days. The formula used in this experiment which A as raw material and B as concentration of Effective Microorganisms are A1 as neem;s seed, A2 as neems leaves; and B as concentration of effective microorganisms which is B1 as 3 %, concentration and B2 as 6 % concentration. The extraction product were evaporated with rotary vacuum evaporator. The extracts obtained were tested their solubility. Azadirachtin were obtained on combination od A1B2 for neem,s seeds for 6 days fermentation period which acquired 1313,23 ppm (61,25 %) of azadirachtin and combination of A2B2 for neem;s leaves which acquired 665,69 ppm (69,17%) of azadirachtin from raw materials. The active compounds were tested their ability as insecticide and showed that 50 ppm of azadirachtin concentration still effective for 14 days evaluation.

Abstract

Dewa leaf (Gynura pseudhochina (Lour) DC) often used as herbal tea to its benefit in reducing blood glucose content. One of the active compound in dewa is pyrrolizidine alkaloid. which is active against tumor. The aim of this research was to identify the active compound of pyrrolizidine in leaves of dewa green tea, black tea and dry powder which are resulted from the experiment. The analysis of pyrolizidine was done by quantitative and qualitative methods. The separation method used for the pyrrolizidine compounds was thin layer chromatograpy using methanol:water(85 : 15) as developing solvent. The determination of pyrrolizidine content was done by TLC scanner. The result showed that the RF value of dewa green tea is 0.34 relatively equal to the pyrrolizidine standard (0.360. While the Rf value of pirolyzidine compound in leaves of dewa black tea and dry powder was 0.42 and 0.41 significantly different from pyrrolizidine standard. The pyrrolizidine compound in leaves of dewa black tea and dry powder could not be detected quantitavely by TLC scanner because its concentration was too small, where as in leaf of dewa green tea the pyrrolizidine compound was detected 0.005%. So, it could be concluded that the contents of pyrrolizidine compound in leaf of dewa green tea was higher than pyrrolizidine content in black tea and dry powder of dewa leaf.
