(-)-Epigallocatechin (Epigallocatechin) is the most abundant flavonoid in green tea, can bind to unfolded native polypeptides and prevent conversion to amyloid fibrils.

Catechin (Standard) is the analytical standard of Catechin. This product is intended for research and analytical applications. Catechin ((+)-Catechin) inhibits cyclooxygenase-1 (COX-1) with an IC₅₀ of 1.4 μM.

(−)-Epiafzelechin is a COX-1 inhibitor with an IC₅₀ of approximately 15 μM against COX-1 activity. (−)-Epiafzelechin also exhibits DPPH free radical scavenging activity, with an EC₅₀ of 20.9 μM. (−)-Epiafzelechin promotes osteoblast differentiation by increasing ALP activity, ECM collagen content and Runx2 expression, while reducing the growth of osteoclast precursors and RANKL-induced TRAP activity, thereby regulating the bone remodeling process. (−)-Epiafzelechin alleviates ovariectomy-induced bone loss. (−)-Epiafzelechin can be used in studies related to bone remodeling, postmenopausal osteoporosis, inflammatory responses and oxidative stress.

(-)-Gallocatechin gallate is the polyphenol isolated from tea, with cancer-preventive activities.

(-)-Gallocatechin gallate (Standard) is the analytical standard of (-)-Gallocatechin gallate. This product is intended for research and analytical applications. (-)-Gallocatechin gallate is the polyphenol isolated from tea, with cancer-preventive activities.

Theaflavin 3,3'-digallate (TF-3) is a potent Zika virus (ZIKV) protease inhibitor with an IC₅₀ of 2.3 μM. Theaflavin 3,3'-digallat directly binds to ZIKVpro (K_d=8.86 μM) and inhibits ZIKV replication. Theaflavin 3,3'-digallat inhibits the activity of gp41 and NS2B-3 protease and has antiviral activity against HSV and HIV-1. Theaflavin 3,3'-digallate, the typical pigment in black tea, is a potent antitumor agent.

Isosakuranetin is a flavanone flavonoid which can be found in the fruit of Citrus bergamia. Isosakuranetin is a TRPM3 blocker.

Leucocyanidin is an active anti-ulcerogenic ingredient was extracted from Litchi Chinensis. Leucocyanidin demonstrates a significant protective effect against Aspirin-induced erosions in rat models.

Theaflavin is a suitable natural inhibitor against influenza A (H1N1) neuraminidase.

Theaflavin-3-gallate, a black tea theaflavin monomer, is regarded as the biologically important active component of black tea and provides health benefits. Theaflavin-3-gallate acts as prooxidants and induces oxidative stress in the carcinoma cells. Theaflavin-3-gallate reacts directly with reduced glutathione (GSH) in a time- and concentration-dependent manner. Theaflavin-3-gallate induces apoptosis and G1 cell cycle arrest in ovarian cancer A2780/CP70 cells through p53-dependent pathways. Theaflavin-3-gallate induces DNA damage through ATM/Chk/p53 pathway.

Theaflavin-3'-gallate is a monomer of theaflavins found in black tea, which has anti-UVB damage activity and inhibits cell apoptosis and necroptosis. Theaflavin-3'-gallate acts as a pro-oxidant and induces oxidative stress in cancer cells, inhibiting xanthine oxidase (OX), with an IC₅₀ of 7.6 μM.

(-)-Catechin is Catechin's one kind of different structure. Catechin inhibitory enzyme-1 (COX-1), IC₅₀ of 1.4 μM. (-)-Catechin promotes hBM-MSC adipose cell differentiation, increases fat cell differentiation, and PPARγ level.

(+)-Gallocatechin is a polyphenol compound from green tea, possesses anticancer activity.

(+)-Catechin hydrate inhibits cyclooxygenase-1 (COX-1) with an IC₅₀ of 1.4 μM.

(-)-Catechin gallate is a minor constituent in green tea catechins. (-)-Catechin gallate inhibits the activity of COX-1 and COX-2 enzymes.

Vestitol ((±)-Vestitol) is an isoflavonoid phytoalexin and Antifungal agent. Vestitol can be isolated from the leaves of Trifolium arvense. Vestitol inhibits the mycelial growth of Helminthosporium carbonum with a ED₅₀ of 17 μg/mL. Vestitol can be used in the research of fungal infections (Helminthosporium carbonum-induced plant diseases).
