Detection of Fungus from Old Plam-leaf Manuscripts Stored in the University of Yangon Library and Biochemical Properties of Citronella Grass
- Citronella grass possess many useful biological activities which has been the reason for the selection of this plant for the present paper. The present paper is concerned with detection of fungus from old palm-leaf manuscripts stored in the University of Yangon Library and biochemical properties of citronella grass (Cymgopogom winterianus Jowitt). Penicillin, Aspergillus, Microrrhizal fungi were detected from old palm-leaf manuscripts by agar plate diffusion method. Essential oil content of citronella grass was found to be 0.6% by steam distillation. Biological activities such as acute toxicity, antifungal, antibacterial, antioxidant and mosquitoes repellent activities of its extracts and essential oil were determined. No acute toxic effect was found in both water and 70% EtOH extracts from citronella grass leaves at maximum dose of 12 g/kg bw. Citronella oil showed significant antifungal activity by using agar well diffusion method. According to GC-MS spectrum, citronellal was the major component of essential oil of citronella grass.
