Figures & data
Figure 1 HPTLC profiles (overly chromatograms) of methanol extract, ethyl acetate fraction, and butanol fraction. Eluent: ethyl acctate:methanol:water (100:13.5:10) (v/v). (a) Detection, 365 nm; (b) detection, 254 nm.
Table 1 Percentage of kaempferol-3-O-rutinoside and astragalin in G. procumbens extract and fractions.
Figure 2 Trolox equivatent antioxidant capcity (TEAC) of Gynura procumbens extract and fraction. Measurments were carried out in triple. Each value a mean ± S D (n = 3).** and *** represent indicate significant difference compared with methanol extract at p < 0.001, respectively.
Figure 3 β-Carotene inhibition activity of the Gynura procumbens extract and fraction at different concentrations. Each value represents a mean ± SD (n = 3).
Figure 4 Xanthine oxidase in inhibition activity of the Gynura procumbens extract and fraction at different concentrations. Each value represents a mean ± SD (n = 3).
Figure 5 Reducing powers of the Gynura procumbens extract and fraction at different concentrations. Each value represents a mean ± SD (n = 3).
Figure 6 DPPH scavenging activity of the Gynura procumbens extract and fraction at different concentrations. Each value represents a mean ± SD (n = 3).
Figure 7 Gallic acid equivant total phenolic contents of the Gynura procumbens extract and fraction. Each value represents a mean ± SD (n = 3).*** indiactes significat differences comared with the methanol extract at p < 0.05.
Figure 8 Linear correlation between the total phenolic contents and (a) trolox equivant antioxidant captacity (TEAC), (b) β-carotene–linoleic acid antioxidant model, (c) xanthine oxidase inhibition, (d) reducuing power, and (e) DPPH seaveing activites of G. procumbents extract and fractions.
