Abstract:

Sedum aizoon L. (SA) has been widely used for treatment of various hemorrhages, insomnia, pain and trauma; however, its anti-inflammatory activity is unknown. In this study, wefirstly investigated the anti-inflammatory activity of SA extracts by petroleum ether (PE), ethyl acetate (EtOAc), and H2O in LPS-stimulated RAW 264.7 cells. Results showed that the EtOAc extract rich in phenolics and flavonoids significantly inhibited LPS-induced NO, TNF-α, and IL-6 production in RAW 264.7 cells (P<0.01), suggesting that this extract possessed potent anti-inflammatoryactivity. The phytochemical profile of the effective extract was subsequently analyzed by HPLC fingerprint with 11 standards. The results indicated that gallic acid, protocatechuic acid, p-hydroxybenzoic acid, ethyl gallate, iriflophene, 5,7-dihydroxy chromone, quercitrin, quercetin, luteolin, kaempferol, and isorhamnetin were present in this extract, which might contribute to its anti-inflammatory activity. Thus, the EtOAc extract of SA showed anti-inflammatory activity and could be used as a potential natural anti-inflammatory agent.
