天然产物 糖类和糖苷 Saccharides and Glycosides

Rhoifolin;(Synonyms: 野漆树苷) 纯度: 99.24%

Rhoifolin 是从琯溪蜜柚 (Citrus grandis) 叶子分离的黄酮糖苷。 Rhoifolin 通过增强脂联素分泌,胰岛素受体-β (insulin receptor-β) 的酪氨酸磷酸化和 GLUT4 易位有益于糖尿病并发症。 Rhoifolin 通过 RANKL 诱导的 NF-κBMAPK 途径改善钛颗粒刺激的骨溶解并减弱破骨细胞生成。

生物活性

Rhoifolin is a flavone glycoside isolated from Citrus grandis (L.) Osbeck leaves. Rhoifolin is beneficial for diabetic complications through enhanced adiponectin secretion, tyrosine phosphorylation of insulin receptor-β and glucose transporter 4 (GLUT 4) translocation[1]. Rhoifolin ameliorates titanium particle-stimulated osteolysis and attenuates osteoclastogenesis via RANKL-induced NF-κB and MAPK pathways[2].
