In this research, the interaction between dihydromyricetin (DMY) obtained from vine tea and iron ions (Fe (II) and Fe (III)) was investigated at pH 3.0, 5.0, and 7.0 with UV absorption and fluorescence quenching spectroscopy. The effects of DMY on the stability and solubility of iron ion were also studied. The results showed the presence of iron ions changed the UV absorption spectra of DMY at the experimental pH values. And the fluorescence spectra showed that iron ion had enhanced fluorescence effect on DMY. In addition, DMY was capable of protecting Fe (II) from being oxidized and improving the solubility of Fe (III).

It is very challenging to prepare carbon dots (CDs) with aggregation-induced emission (AIE) property for simultaneous sensitive sensing and efficient removal. Herein, blue-emission CDs were facilely prepared by one-step solvothermal treatment of vine tea. Optical characterizations demonstrated that AIE phenomenon of CDs came from the restricted intramolecular motion.

Dihydromyricetin (DHM), the primary active compound in vine tea possesses various pharmacological effects such as anti-inflammatory and antioxidant properties, along with high biosafety. However, its oral delivery remains a significant challenge. Montmorillonite (MMT), the primary component of bentonite, is a commonly used drug in the clinical treatment of gastrointestinal diseases and serves as an excellent drug carrier due to its intercalation capability.

Vine tea extract (VTE), from the traditional Chinese herbal tea, was added to reconstituted skimmed milk; the mixture was fermented with , and fermentation characteristics, flavonoid content, antioxidant capacity (AOC), and viability of were measured. 2 mg/mL VTE promoted growth and 8 mg/mL VTE inhibited growth, an effect consistent with observed pH changes. Total flavonoid content and AOC increased with increasing VTE dosage.
