The aim of this paper is the isolation of individual compounds, which are caused the antibacterial activity of the leaves of the bearberry [Arctostaphylos uva-ursi (L.) Spreng.]. The leaves of Arctostaphylos uva-ursi, collected in Perm region, there were extracted with 70% ethanol, the obtained water-alcoholic infusion there was evaporated in vacuum.By means of the chromatographic methods with the using of silica gel 40/100 and eluent systems (chloroform and ethanol in several ratio) from the evaporated water-alcoholic extract of the leaves of Arctostaphylos uva-ursi, a substance with antibacterial activity, ethyl ester of p-digallic acid, which is a new natural compound, was isolated along with arbutin ((1-О-b-D-glucopyranoside of hydroquinone) from the leaves of this plant. The chemical structures of the ethyl ester of p-digallic acid and arbutin were established with the using of data of 1H-NMR-spectroscopy, UV-spectroscopy and mass-spectrometry..The antibacterial activity of ethyl ester of p-digallic acid against test cultures of gram-positive bacteria Bacillus cereus and Staphylococcus aureus, gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa for the first time was determined. By antibacterial activity, arbutin was inferior not only to ethyl ester of p-digallic acid, but also to decoction from the leaves of the bearberry. Consequently, the ethyl ester of p-digallic acid is one in main component, which is take the contribution in the antibacterial activity of the decoction and other preparations of the leaves of Arctostaphylos uva-ursi.

Mallotus oblongifolius (MO), which is rich in polyphenols, is a characteristic tea resource with medicinal value. In this study, a total of 45 polyphenolic components of MO, including narirutin, isoquercitrin, rutin and digallic acid, were identified by UPLC-Q-TOF/MS analysis. In addition, the gastroprotective effect of Mallotus oblongifolius polyphenols (MOP) on ethanol-induced gastric mucosal injury in rats was investigated. The rats received anhydrous ethanol after continuous gavage of MOP or lansoprazole for one week. In addition, the macro- and micro-damage induced by ethanol in the gastric tissue was significantly reduced after MOP pretreatment for one week. Further analysis showed that MOP prevented ethanol-induced acute gastric mucosal injury by increasing the expression of antioxidant enzymes (SOD, CAT, GSH-Px) and decreasing the expression of reactive oxygen species (ROS), lipid oxidation product (MDA) and myeloperoxidase (MPO). Meanwhile, MOP inhibited the phosphorylation of p38/ERK/JNK and promoted the activation of the Nrf2 pathway. These results suggested that MOP may be a promising therapeutic target for the prevention of ethanol-induced gastric mucosal injury by improving oxidative stress, inhibiting the p38/ERK/JNK signaling pathways and activating Nrf2 expression.
