Microbial Enumeration of Selected Curcuma Species Herbal Based Products


Medicinal and Aromatic Plants Seminar (MAPS 2008)


21st October - 22nd October 2008

Place Held

The Legend Hotel, Kuala Lumpur


A microbial enumeration test was conducted to determine the total number of aerobic microorganism present in herbal products incorporated with Curcuma species particularly from Curcuma xanthorrhiza and Curcuma domestica. Ten herbal products of oral dosage from available in the market were randomly chosen in this study. The selected herbal products were five maajun (M1, M2, M3, M4 and M5), four capsules (C6, C7, C8 and C9) and one herbal drink (D1O). Total number of bacteria and fungi were measured by aerobic plate count. Total aerobic microbial count (TAMC) was determined on trypticase soy agar and incubated for 3-5 days at 35°C. For total yeast and moulds count (TYMC) was determined on sabouraud dextrose agar and incubated for 5-7 days at 25°C. Of the ten products tested, only two products which were herbal drink D10 and maajun M4 complied with safety limit in both 2 categories. The worst was the maajun M3 which had 430 times and 39000 times excess for TAMC and TYMC, respectively. From the finding, 90% of the herbal products tested were contaminated with microorganisms and it is maybe due to unhygienic condition in the stages of sample preparation, production, processing and packaging.
