Two bioactive flavone glycosides, astragalin and kaempferol-3-O-glucuronide, were analyzed in Alpinia nigra (Gaertn.) Burtt by HPLC. The method was validated in detail. Kaempferol-3-O-glucuronide was found to be a dominant compound in the seed clusters. It is primarily distributed in the pulp. In addition, volatile oils of fruits and rhizomes of A. nigra were studied by GC-MS. β-Pinene and α-pinene were found to be major constituents of the volatile oil of the fruits.
