HPLC was used for the component analysis of the polysaccharide. The results indicate that Physalis alkekengi L. polysaccharide（PAP） was composed of rhamnose, xylose, arabinose, galactose, and glucose. Free radicals scavenging activity of PAP was studied through 3 free radicals scavenging tests. PAP exhibited high scavenging effects on OH and DPPH radicals, and both the scavenging rates were about 80%. The scavenging rate of O2^- radical was about 22%.展开更多

Despite several previous studies evidencing the anticancer potential of Physalis angulata;however, certain study that proves its benefits in retinoblastoma cancer cells has been limited.METHODS: This study utilizes an in-vitro experimental study by applying Y79 human retinoblastoma cell line culture obtained from the American Type Culture Collection(ATCC;10801 University Boulevard Manassas, VA 20110, USA). The cell was divided into 4 groups. Group I was the control group without the administration of Physalis angulata leaf extract. Whereas, group II, II and IV are engaged with 25, 50, and 100 μg/mL of Physalis angulata leaf extract respectively. After a 24 h incubation, an examination with microtetrazolium(MTT) cell proliferation assay and Annexin V apoptosis detection was conducted. Statistical analysis was performed with the Tukey test.RESULTS: Physalis angulata leaf extract improved apoptosis and significantly reduced the number of living cells in retinoblastoma cells, along with the increase in the given dose. Based on the Tukey test, a significant difference was found in the treatment group at 50 μg/mL(P=0.025) and 100 μg/mL(P=0.001) in the measurement of apoptosis. Proliferation measurements also indicated a significant decrease in the number of living cells in the 50μg/m L treatment group(P=0.004), and in the 100 μg/mL treatment group(P=0.000). Meanwhile, a dose of 25 μg/mL indicated insignificant difference in the two measurements. Improved apoptosis and decreased number of living cells occured at a dose of 100 μg/mL. Decreased number of living cells(in the measurement of proliferation) was due to the inhibited proliferation or improved apoptosis.CONCLUSION: Physalis angulata leaf extract improve apoptosis in retinoblastoma cell culture, requiring further research to inhibit proliferation.展开更多
