Abstract

Microencapsulation Kaffir lime oil (C. hystrix DC.) has advantages such as capable of controlling the evaporation process, oxidation by air or oxygen and release the active ingredient is stable, thus providing a constant concentration over long periods of therapy. In this research microencapsulation of kaffir lime oil from leaves (MJP-D) and rind (MJP-KB) using chitosan to crosslinking with glutaraldehyde (ratio 2:1). Characterization of kaffir lime oil use Gas chromatography-mass spectrometry (GC-MS), characterization of microcapsule use FTIR and particle size analyzer, while analysis of essential oil content in the microcapsules with UV-Vis spectroscopy. Composition of MJP-D consist of citronellal (85,07%), lonalool (3,47%), citronelil acetate (2,77%) and sabinene (2,79%), while MJP-KB consist of citronellal (20,91%), terpinen-4-ol (11,93%), a-pinene (21,44%) and limonene (12,59%). Microcapsul MJP-D and MJP-KB has a distinctive absorption crosslinking results on 1558 cm-1 (-C=N) and particle size 340,43-404,90 nm. The effectiveness microcapsulation of MJP-D and MJP-KB 37,5% and 86,88% with each zone of inhibition against Pseudomonas aeruginosa bacteria is 12,8 mm and 17,1 mm. Keywords: microcapsul, kaffir lime oil, antimicrobial P. aeruginosa

Abstract

Kaffir lime oil (C. hystrix DC.) is consist of a complex mixture of hydrocarbons terpenoids and terpenoids which contain oxygen are distributed in every part of the plant. In this research tested the antioxidant and antimicrobial activity, both against kaffir lime oil from twigs, leaves and rind including the main components citronellal. The antioxidant was evaluated by testing its ability to catch DPPH radical. Antimicrobial activity is measured by its ability to inhibit the growth of gram-negative bacteria, Escheria coli. Gas chromatography-mass spectrometry (GC-MS) is used to analyze chemical composition of kaffir lime oil. Value of IC50 of kaffir lime oil obtained was 6,43 (mL/mL); 6,83 (mL/mL); 9,48 (mL/mL) and 10,1 (mL/mL), consecutive to kaffir lime oil from rind, leaves, twig-leaf mixture and citronellal. Compared to the other kaffir lime oil and major components citronellal, kaffir lime oil from rind show the most vigorous activity in inhibiting growth of Escheria coli bacteria, by MIC values of 12,5 (mL/mL). GC-MS analysis showed that citronellal and citronellol as major component on kaffir lime oil from leaves and twig-leaf mixture, while the major component of kaffir lime oil from rind is b-pinene, limonene, citronellal dan terpinen-4-ol. Keywords: kaffir lime oil, citronellal, citronellol, antioxidant, antimicrobial
