Abstract:
The rhizomes of
Boesenbergia rotunda,
Zingiber purpureum, and
Alpinia galangal are well-known Thai medicinal plants has been used as spice and folk medicine due to its numerous functional and nutritional properties. The present study, the anti-platelet aggregation activities of the ethanol extracts from the rhizomes of rhizomes of
B. rotunda,
Z. purpureum, and
A. galangal were evaluated using 96-well plate platelet aggregation assay. The ethanol extracts from
B. rotunda,
Z. purpureum,
A. galanga (IC50 0.064 ± 0.039, 0.019±0.721, and 0.113±0.031 µg/mL) were more active than the ibuprofen (IC50 0.439 ± 0.064 µg/mL) in ADP-induced platelet aggregation (
P<0.05). The inhibitory activity of extract from
Z. purpureum (IC50 0.024±0.08 µg/mL) was comparably active to the ibuprofen (IC50 0.036±0.006 µg/mL) in the AA induced platelet aggregation; however, the extracts from
B. rotunda and
A. galangal (IC50 0.054±0.031 and 0.068±0.026 µg/mL) were less potent than ibuprofen (
P<0.05).The ethanol extracts from
B. rotunda and
Z. purpureum (IC50 0.025±0.008 and 0.012±0.015 µg/mL) were more potent than ibuprofen (IC50 0.056±0.023 µg/mL) in collagen-induced platelet aggregation (
P<0.05). The extracts from
Z. purpureum and
A. galanga (IC50 225±0.094 and 190±0.075 µg/mL) possessed inhibitory activities on thrombin-induced platelet aggregation. The ethanol extracts from the rhizomes of rhizomes of
B. rotunda,
Z. purpureum, and
A. galangal were inactive in the platelet aggregation assay using U-46619 and TRAP-6 as agonists.
