Quercetin-3-O-[(6-caffeoyl)-β-glucopyranosyl (1→3) α-rhamnopyranoside]-7-O-α-rhamnopyranoside 可以从蕨类植物 Ophioglossum vulgatum L 的地上部分分离出来，具有伤口愈合活性。

激动素是细胞分裂素的一种，是一类促进细胞分裂的植物激素。

Potent, high affinity apelin receptor agonist (IC50 = 0.27 nM; Kd = 0.51 nM). Exhibits no binding GPR15 and GPR25. Activates the PI3K/AKT pathway and promotes self-renewal of hESCs via cell-cycle progression and protein translation. Also potentiates the TGFβ pathway, priming hESCs toward the endoderm lineage. Stimulates angiogenesis in HUVEC cells. Relaxes mouse aortic vessels. Functions as an anorexigenic hormone through activation of the AVP and CRH neurons in the PVN.
