| Abstract: | Two new flavonoids named castilliferol 1 and castillicetin 2, as well as a known compound, isochlorogenic acid 3, were isolated from the whole plant of Centella asiatica. Isolates 1 and 2 exhibited good antioxidant activity using 2,2-diphenyl-1-picryl hydrazyl radical solution with IC50 values of 23.10 and 13.30, respectively. The structures of these isolates were determined by analytical and spectral data,
including 1-D and 2-D NMR spectra. |
