Research articles related to Alpinia galanga:
Anti- melanoma activity: Two compounds, 1,7-bis(4-hydroxyphenyl)-1,4,6-heptatrien-3-one (BHPHTO) and bisdemethoxycurcumin (BDMC) they have been isolated from the rhizomes of Alpinia galangal, and the structures of both pure constituents were determined using spectroscopic analyses. The study examined the bioeffectivenesses of the two compounds on the human melanoma A2058 and showed that significantly inhibited the proliferation of melanoma cells in the cell viability assay.

Anti- microbial activity: The present study was carried out to determine antimicrobial and radical scavenging effect of leaf and rhizome extract of A. galanga. The powdered leaf and rhizome were extracted by soxhlet extraction using methanol. Antimicrobial activity of extracts was determined by Agar well diffusion assay against 15 clinical isolates of bacteria (from burn, dental caries and urinary tract infection) and two fungi (Candida albicansand Cryptococcus neoformans). Rhizome extract was found to possess high inhibitory activity against fungi and clinical isolates of bacteria. The plant can be used for the development of agents active against pathogenic microbes and radical induced damage.

Action against gastric cancer cells: This study evaluated the effect of Alpinia galangal on AGS cells (human gastric adenocarcinoma epithelial cell line) and L929 cells (as a standard cell line originated from mouse fibroblast cells). After culturing the cells in Roswell Park Memorial Institute (RPMI) medium, the cells were incubated with different doses of Alpinia galangal (0 (control), 125, 250, 500, 750 and 1000 µg/ml) in 24, 48 and 72 hour periods and then, cells viability were assessed using MTT based cell proliferation assay. After 24 hours, the percentage of living AGS cells compared to the control group showed no significant decrease at the concentrations of 125 and 250µg/ml. But in the rest concentrations were significant (p<0.05). We have demonstrated, using cell culture model, anti-proliferative effect of aqueous extract of Alpinia galangal on human gastric tumor (AGS) and L929 cell lines. This effect was prominent in high concentrations.
