Sample preparation and anti-inflammatory activity screening. NO generation (b) and cytotoxicity (c) of SPE and its fractions on LPS-stimulated RAW 264.7 cells. NO production was measured by Griess assay and cell viability was measured by MTT assay. The data were expressed as the mean ± SE (n = 3). ^*p < 0.05, ^**p < 0.01 as compared to LPS only-treated group and ^##p < 0.01 as compared to control group
