Abstract

Isolation of two essential oils of Baeckea frutescens L. leaves from different locations (Yogyakarta and Semarang) was done by hydrodistilation. The chemical composition of the oils were analysed by GC-MS. The oils were found to possess chemical compositional differences and considerable variation in the levels of each chemical components, suggesting the existence of chemical varieties.The oils were dominated by monoterpene i.e 8-cineole (22,08-22.67%) and P-pinene (17,98-29.22%).Comparison of chemical composition of the oils analyzed in this study and oils from literatures was conducted to study the effect of environmental factor on the essential oil composition.The result showed that temperature, irradiance, photoperiod and altitute factors influence the chemical composition of essential oils. Tasmanone, a non-terpenic triketone only appears in the essential oils from Quang Binh province (north Vietnam), that have extreme environmental condition.

Abstract

Ethanol 95% and water extracts of Kaempferia spp. (K. galanga, K. angustifolia, K. pandurata and K. rotunda) were tested for their influences in in-vitro phagocytosis activity and phagocytosis capacity of mouse peritoneum macrophage cells induced by Staphylococcus epidermidis. Extracts were tested at a series concentration in logarithmic order (0.1-1000) ug/ml. Imboost and distilled water were employed as positive and negative controls, respectively. The results shows that almost all extracts were capable to increase on phagocytosis activity (SPA - Screening for Phagocytosis Activity) and phagocytosis capacity (IP • Index Phagocytosis) of macrophage cells compared to positive and negative controls significantly (p<0.05).The phagocytosis activity and capacity macrophage cells were increased by increasing extract concentration. K.rotunda extracts shows reveal better on above activities in low concentration (0.1-100) ug/ml then other species.
