Biological Activities
Geum japonicum serves as a versatile plant utilized in both functional nutrition and traditional folk medicine across Asia. Research into its chemical constituents reveals that specific tannins isolated from the plant exhibit potent anticoagulant activity by inhibiting key enzymes like thrombin and factor Xa. Furthermore, the plant is a significant source of ellagic acid, a compound highly valued for its medicinal and cosmetic applications. Studies using green extraction methods have demonstrated that these extracts possess strong antioxidant properties, particularly through their ability to scavenge DPPH radicals. Together, these biological activities highlight the significant therapeutic potential of Geum japonicum in managing blood coagulation and oxidative stress.
Compounds
Geum japonicum serves as a rich source of diverse bioactive secondary metabolites with significant pharmacological potential. Research involving the methanol extract of the whole plant has identified several important tannins, including 5-desgalloylstachyurin and casuariin. Furthermore, the plant contains various triterpene acids, such as epipomolic acid and euscaphic acid, which have demonstrated inhibitory effects against HIV-1 protease. The botanical profile is further enriched by the presence of eugeniin, a compound noted for its potent anti-herpesvirus activity. Collectively, these chemical constituents highlight the therapeutic versatility of Geum japonicum in addressing viral and coagulation-related conditions.
Conditions
Geum japonicum contains active compounds like 3,4,5-trihydroxybenzaldehyde that treat the DNA binding of nuclear factor (NF)-kappaB and activator protein (AP)-1 transcription factors. The plant's tannins also provide therapeutic effects by treating Factor Xa through competitive inhibition. Furthermore, Geum japonicum treats the activities of MMP-2 and MMP-9 within human aortic smooth muscle cells (HASMCs). Specifically, it treats the MMP-9 and MMP-2 activity found in the supernatants of TNF-alpha-induced HASMCs. Finally, the plant treats MMP-9 expression and the migration of these TNF-alpha-induced HASMCs.
Preparations
Geum japonicum is utilized in China and other Asian nations as a type of folk medicine and as functional vegetables. The plant is also prepared as a MeOH extract to isolate tannins that influence blood coagulation. Furthermore, Geum japonicum is prepared as a methanol extract to identify triterpene acids that inhibit the HIV-1 protease. Research has also shown that the hot-water extract of the plant exhibits anti-herpes simplex virus activity.
