Kaempferol 3-sophoroside-7-glucoside, a flavonoid found in Lei leaves, exhibits bioactive properties including antioxidant and anti-obesity activities.

The roasting process followed by a 30% EtOH extraction tended to enhance the content of kaempferol-3-sophoroside-7-glucoside. It effectively inhibited pancreatic lipase activity by 62.50 ± 4.81%, which was approximately 1.71 percentage points higher than that of the dried-nonroasted LCL extract (60.79 ± 3.75%). Its bioaccessible fraction obtained from in vitro digestion significantly and dose-dependently reduced intracellular lipid accumulation by adipocyte 3T3-L1 compared with a 30% EtOH extraction. At a concentration of 200 μg/mL, it inhibited lipid accumulation up to 29.55% in 3T3-L1 cells, which indicated that human digestive enzymes converted kaempferol-3-sophoroside-7-glucoside to kaempferol metabolites that have anti-obesity effects.[1]

Apigenin 7-O-β-D-glucopyranoside and kaempferol-3-sophoroside-7-glucoside, among others, were the main chemical constituents of Pteris wallichiana J. Agardh extract (PEW). In LPS-induced Raw264.7 inflammation and DSS-induced mouse colon UC, PEW pretreatment can significantly reduce the expressions of inflammatory cytokines in vitro and in vivo. In DSS-induced UC mice, PWE can improve the abnormal pathological tissue damage by inhibiting oxidative stress and inflammation-related signaling pathways, and improve the intestinal barrier function.[1]
