Theasinensin C is an orally effective renin inhibitor and gut microbiota modulator, with an IC₅₀ of 40.21 μM against renin activity. Theasinensin C selectively enriches Akkermansia muciniphila in the gut microbiota, enhances the Akkermansia muciniphila-mediated hydrolysis of the PTS domain of mucin, drives the accumulation of luminal glutamine and serine, and regulates the gut-kidney-liver glutamine/serine metabolic signaling pathway to promote creatine biosynthesis. Theasinensin C improves cognitive function, reduces pro-inflammatory cytokines, alleviates neuropathological changes and restores intestinal barrier integrity. Theasinensin C can be used in research related to hypertension and neuroinflammation induced by high-fructose diet.

Theaflavin 3,3'-digallate (Standard) is the analytical standard of Theaflavin 3,3'-digallate. This product is intended for research and analytical applications. 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 (Kd=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.

Neotheaflavin, from black tea, inhibits pancreatic lipase.

Epitheaflagallin 3-O-gallate is a minor polyphenol in black tea. Epitheaflagallin 3-O-gallate exhibits versatile physiological functions in vivo and in vitro, including antioxidative activity, pancreatic lipase inhibition, Streptococcus sorbinusglycosyltransferase inhibition, and an inhibiting effect on the activity of matrix metalloprotease-1 and -3 and their synthesis by human gingival fibroblasts.

Purpurogallin carboxylic acid, isolated from Macleaya microcarpa (Maxim.) Fedde, is an oxidation product of gallic acid in fermented tea. Purpurogallin carboxylic acid has anti-cancer activity.

Talienbisflavan A is a free radical scavenger found in green tea made from the leaves of Camellia taliensis. Talienbisflavan A mediates DPPH radical scavenging activity. Talienbisflavan A mediates ABTS⁺ radical scavenging activity. Talienbisflavan A exhibits antioxidant activity.

Camellia nitidissima polysaccharide is a polysaccharide derived from Camellia nitidissima.

(Z)-3-Hexenal is an isomer of Hydrosorbaldehyde (HY-W747972). (Z)-3-Hexenal is a green leaf volatile and also the main contributor to the fresh, grassy aroma of tea leaves. (Z)-3-Hexenal undergoes irreversible conversion to (E)-2-hexenal via (Z)-3:(E)-2-hexenal isomerase (CsHI). (Z)-3-Hexenal plays a key role in protecting plants against biotic stresses (such as pathogens and insects) and acting as a signaling chemical.
