Abstract:

The air-dried and powdered methanol solvent extraction of the rhizomes of Alpinia galangal is subjected to bio-assay guided fractionation and isolation yielded a known compound namely, 1'-S-1'-Acetoxychavicol acetate (1). The isolated known compound has been identified based on the physical, spectral data (IR, ¹H, ¹³C, NMR and mass spectroscopy) and comparison with an authentic sample. Finally isolated 1'-S-1'-Acetoxychavicol acetate (1) was confirmed by synthesis. The crude methanol extract and identified known compound (1) were tested for antidandruff property against Malassezia furfur showed with MIC 1000 µg/mL and 7.81 µg/mL, respectively.
