Determination of Biologically Active Substances - Flavonoids in Fruit Trees With Healing Properties

Abstract

The article cites the results on the amount of flavonoid content in the birch trees. Flavonoids are synthesized only in plants and have important biological significance in the human body. The results show that in spring the content of flavonoids in grape leaves was high and amounted to 4.721 ± 0.521 mg/g, in the summer they were 3.825 ± 0.255 mg/g, and in the fall, flavonoids decreased to 1.460 ± 0.2253 mg/g. In spring, flavonoids in the stems of grapes were 4.386 ± 0.046 mg/g, in cocoons 0.348 ± 0.023 mg/g.

The effect of some pesticides on lipid peroxidation and on the content of cytochrome p-450 of mitochondrial membranes and liver microsomes of pregnant rats and their embryos

“…It was also shown that experimental rats inoculated with the pesticide on the 5th day after poisoning showed a sharp increase in the activity of SOD and glutathione reductase. The observed increase in enzyme activity can be considered as a protective, adaptive reaction of the body against lipid peroxidation, which disrupts the structure and function of cell membranes [4,5].…”

Effect of pesticides “Butylcaptax (Russia)” and “Droppa (Russia)” on respiration and oxidative phosphorylation of liver mitochondria of pregnant rats and their embryos

“…The low rate of oxygen uptake in 1-4 -cell mouse embryos begins to increase at the 8 cell stage and grows 3.5 times at the blastocyst stage. An increase in the utilization of substrates of the tricarboxylic acid cycle at the stage of 4-8 cells indicates an increase in the permeability and transport of substrates into mitochondria [8].…”

“…At the early stages of embryogenesis, there is a high conjugation of respiration and phosphorylation, and at the later stages, these processes are disconnected [8]. In the mitochondria of the liver of embryos, the respiratory control index is low; therefore, they are not efficient producers of ADF [9].…”
