Spiraeoside has antioxidant, anti-inflammatory, ulcer preventive and gastroprotective activities, it inhibits mast cells activation and IgE-mediated allergic responses by suppressing phospholipase C-γ-mediated signaling. Spiraeoside shows anti-plasmin activity, which is considered to play a key role in UV-stimulated melanogenesis in human skin. Spiraeoside is a new inhibitor of the DENV-NS5 RdRp from Carpolepis laurifolia as a potential antiviral drug for dengue treatment. Quercetin 4'-O-beta-D-glucopyranoside is a quercetin O-glucoside that is quercetin with a beta-D-glucosyl residue attached at position 4'. It has a role as an antioxidant, an antineoplastic agent and a plant metabolite. It is a beta-D-glucoside, a member of flavonols, a tetrahydroxyflavone, a monosaccharide derivative and a quercetin O-glucoside. It is functionally related to a beta-D-glucose. It is a conjugate acid of a quercetin 4'-O-beta-D-glucopyranoside(1-).

Yangambin is a selective antagonist of the cardiovascular effects of platelet activating factor (PAF); it has hypotensive effect, which is probably due to a peripheral vasodilatation that involves, at least, the inhibition the Ca2+ influx through voltage-gated Ca2+ channels. Yangambin has central nervous system activity, it presents a depressant activity in the open field, forced swimming and pentobarbital sleeping time tests.

Velutin has strong anti-inflammatory activity, it can effectively inhibit the expression of proinflammatory cytokines TNF-α and IL-6 in low micromole levels by inhibiting NF-κB activation and p38 and JNK phosphorylation. Velutin controls HIF-1α activity during PgLPS-activated osteoclastogenesis probably through modulation of the NF-κB pathway, perhaps it could be used therapeutically to prevent bone loss seen in periodontitis.Velutin can induce apoptosis in tumor cells. Velutin is a dimethoxyflavone that is luteolin in which the hydroxy groups at positions 7 and 3' are replaced by methoxy groups. It has a role as an antioxidant, an antibacterial agent, an anti-allergic agent, a melanin synthesis inhibitor, an anti-inflammatory agent and a plant metabolite. It is a dimethoxyflavone and a dihydroxyflavone. It is functionally related to a 4',5,7-trihydroxy-3'-methoxyflavone.
