Pectolinarin is a disaccharide derivative that consists of pectolinarigenin substituted by a 6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. It has a role as an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor, an antioxidant, an antineoplastic agent, an anti-inflammatory agent, an apoptosis inducer and a plant metabolite. Pectolinarin has antioxidant, antiobesity, analgesic, and hepatoprotective activity, it may inhibit eicosanoid formation in inflammatory lesions.

Oroxin B can selectively induce tumor-suppressive ER stress and concurrently inhibit tumor-adaptive ER stress in B-lymphoma cells for effective anti-lymphoma therapy.

Xanthatin is a novel potent inhibitor of VEGFR2 signaling, has significant antitumor activity against a variety of cancer cells through cell cycle arrest and apoptosis induction, it can inhibit angiogenesis and tumor growth in breast cancer cells. Xanthatin has bactericidal and fungicidal activity, including against Colletotrichum gloesporoides, Trichothecium roseum, Bacillus cereus and Staphylococcus aureus.
