Assessment of the hypoglycemic activity of trans-cinnamic acid isolated from the extract of hairy rots Scutellaria baicalensis in in vivo experiments

AnnotationHypoglycemia is the process of reducing blood glucose concentration to below 2.5-2.8 mmol/L in men and less than 1.9-2.2 mmol/L in women. Prolonged hyperglycemia can lead to a range of serious chronic complications such as diabetic nephropathy, diabetic retinopathy, cardiovascular diseases in diabetes, and so forth, threatening human life, health, and safety. Scutellaria baicalensis is one of the most commonly used remedies in traditional Chinese medicine. This plant contains a number of biologically active compounds that contribute to improving kidney function, insulin resistance, and retinopathy in patients with type 2 diabetes, but few researchers study the toxic effects of medicinal plant components. Therefore, the aim of this study was to evaluate the hypoglycemic activity of trans-cinnamic acid isolated from the extract of hairy rots of Scutellaria baicalensis in in vivo experiments. This study involved intraperitoneal administration of alloxan at a dose of 150.0 mg/kg and oral administration of trans-cinnamic acid at doses of 50.0 and 100.0 mg/kg. During the experiment, it was found that trans-cinnamic acid at the presented doses does not affect the body weight dynamics of experimental animals with diabetes. Thus, this study demonstrates that trans-cinnamic acid at the presented dosage can be safely used as an ingredient in the creation of dietary supplements for the prevention of diabetes, thereby contributing to healthy aging.

Study of the hepatotoxicity of trans-coric acid isolated from Scutellaria baicalensis in in vivo experiments

Biologically active supplements (BAS) based on plant material, possessing a wide range of beneficial properties (antioxidant, anti-inflammatory, antimicrobial, etc.), are becoming increasingly popular worldwide. Such supplements are readily available and can be used without consulting a healthcare professional. Consequently, the extent of their use is underestimated by doctors. Plant hepatotoxicity is not uncommon, but the frequency and manifestation are not sufficiently characterized. This study is dedicated to investigating the hepatotoxicity of trans-coric acid isolated from the root culture of Scutellaria baicalensis in in vivo experiments. This work aims to evaluate the hepatotoxicity of trans-coric acid on male rats at doses of 50.0 and 100.0 mg/kg. During the experiment, it was found that trans-coric acid, isolated from the root culture extract of Scutellaria baicalensis, does not induce hepatotoxicity in the presented doses in model animals with 14-day intragastric administration. Thus, this study demonstrates that trans-coric acid can be safely used as a component of BAS for the prevention of chronic diseases, thereby promoting healthy aging.

Effect of Mangiferin Isolated from Hedysarum neglectum L. Root Culture on Fat Accumulation in Experiments In Vivo

Plant polyphenols possess diverse medicinal and therapeutic properties. For instance, they can prevent such age-related diseases as stroke, heart attack, type II diabetes, and their various pathological complications. Mangiferin is a polyphenolic compound with a C-glycosylxanthone structure. This biologically active substance is known for its antioxidant, anti-inflammatory, antimicrobial, antidiabetic, and immunomodulatory properties. This research features mangiferin isolated from Hedysarum neglectum L. root culture and its effect on fat accumulation in Caenorhabditis elegans N2 Bristol. A set of experiments in vivo proved that mangiferin was able to inhibit fat accumulation in the model organism. The optimal concentration was determined as 50 m: it provided 44.5% fluorescence.

Effect of quercetin and kaempferol isolated from the Ginkgo biloba L. suspension culture extract on lipofuscin accumulation

Lipofuscin, known as an age pigment, is an autofluorescent lipopigment formed by lipids, metals, and misfolded proteins that accumulates in nerve cells, heart muscle cells, and skin. Individual bioactive compounds obtained from medicinal plant extracts reduce the level of lipofuscin in C. elegans nematodes in in vivo experiments. We aimed to study the effect of quercetin and kaempferol isolated from the in vitro suspension culture extracts of Ginkgo biloba L. on the accumulation of lipofuscin. According to the results, 200 M concentrations of these bioactive compounds showed the maximum decrease in lipofuscin levels in C. elegans N2 Bristol during their 15-day cultivation, compared to the control. Thus, our study showed that quercetin and kaempferol are able to reduce this age pigment in in vivo experiments.
