Tannic acid Datasheet

The hepatocarcinogenicity of tannic acid.

In the group of chemical hepatocarcinogenic agents, the number of which has steadily increased in recent years (:$7), tannic acid deserves attention. Owing to its astringent effect, this compound was formerly used widely in therapy. The local treatment of thermal burns with tannic acid was suggested by Davidson (1935), and his procedure was generally employed in Hungary during World War II. I t...

Synthesis and Bioactivity Characterization of Scutellarein Sulfonated Derivative.

Scutellarin (1) has been widely used to treat acute cerebral infarction in clinic, but poor aqueous solubility decreases its bioavailability. Interestingly, scutellarin (1) could be metabolized into scutellarein (2) in vivo. In this study, a sulfonic group was introduced at position C-8 of scutellarein (2) to enhance the aqueous solubility of the obtained derivative (3). DPPH (1,1-diphenyl-2-pi...

Formulation for Oral Delivery of Lactoferrin Based on Bovine Serum Albumin and Tannic Acid Multilayer Microcapsules

Lactoferrin (Lf) has considerable potential as a functional ingredient in food, cosmetic and pharmaceutical applications. However, the bioavailability of Lf is limited as it is susceptible to digestive enzymes in gastrointestinal tract. The shells comprising alternate layers of bovine serum albumin (BSA) and tannic acid (TA) were tested as Lf encapsulation system for oral administration. Lf abs...
