(-)-catechin-3-O-gallate is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of ()-catechin. It has a role as a metabolite. It is a polyphenol, a gallate ester and a member of flavans. It is functionally related to a gallic acid and a (-)-catechin. It is an enantiomer of a (+)-catechin-3-O-gallate. Catechin, a cyclooxygenase-1 (COX-1) inhibitor with an IC50 of 1.4 μM, which has antiangiogenic, antitumor, antioxidant, UV-protective, anti-aging, phytotoxic, antimicrobial, and antiviral effects. Catechin shows its potential as biobased active packaging for fatty food, and exerts cardioprotection through treating many kinds of angiocardiopathy.

Hypericin is a photosensitive antiviral with anticancer and antidepressant agent . It can inhibit tyrosine kinases with IC50 of 7.5 μM. It can induce both apoptosis and necrosis in a concentration and light dose-dependent fashion, and inhibit RANKL-mediated osteoclastogenesis via affecting ERK signalling in vitro and suppresses wear particle-induced osteolysis in vivo. Hypericin is a carbopolycyclic compound. It has a role as an antidepressant. It derives from a hydride of a bisanthene.

Betulinic acid is a pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-carboxy substituents. It is found in the bark and other plant parts of several species of plants including Syzygium claviflorum. It exhibits anti-HIV, antimalarial, antineoplastic and anti-inflammatory properties. It has a role as an antineoplastic agent, an antimalarial, an EC 5.99.1. Betulinic acid is a natural pentacyclic triterpenoid, acts as a eukaryotic topoisomerase I inhibitor, with an IC50 of 5 μM, and possesses anti-HIV, anti-malarial, immunomodulatory, anti-inflammatory and anti-tumor properties.Betulinic acid is a selective inducer of apoptosis in tumor cells, it inhibits activation of NF-kappaB and NF-kappaB-regulated gene expression induced by carcinogens and inflammatory stimuli.
