Glycyrrhizin, a triterpenoid saponin derived from the underground parts of Glycyrrhiza plants (licorice), has several pharmacological activities and is also used worldwide as a natural sweetener. The biosynthesis of glycyrrhizin involves the initial cyclization of 2,3-oxidosqualene to the triterpene skeleton β-amyrin, followed by a series of oxidative reactions at positions C-11 and C-30, and g...
Glycyrrhizic acid (GA) is a triterpene glycoside found in the roots of licorice plants (Glycyrrhiza glabra). GA is the most important active ingredient in the licorice root, and possesses a wide range of pharmacological and biological activities. GA coupled with glycyrrhetinic acid and 18-beta-glycyrrhetic acid was developed in China or Japan as an anti-inflammatory, antiviral, and antiallergic...
در این تحقیق پودر تفاله چای برای حذف رنگزای acid brill scarlet 3r (acid red 18) مورد بررسی قرار گرفته است. خصوصیات سطح تفاله چای با استفاده از semبررسی شد. اثر متغیرهای فرایند همچون مقدار جاذب، غلظت اولیه رنگ، ph، زمان و دما مطالعه شد. داده ها برای تطابق با مدل های ایزوترم لانگمویر، فروندلیچ، تمکین ودابینین - رادوشکوویچ ارزیابی شد. نتایج نشان داد که داده ها برای جذب سطحی acid red 18 برروی تفاله...
Background and purpose: Gastric cancer is one of the most common cancers and the second common cause of cancer death worldwide. Surgery is the only treatment for gastric cancer but about 50% percent of patients have inoperable tumors. For these patients, combined chemotherapy is the primary treatment which has some side effects. CXCR4 that is expressed on the surface of tumor cells plays a role...
THE TITLE COMPOUND [SYSTEMATIC NAME: 11-oxo-2,3-(oxy-dinitrilo)olean-12-en-29-oic acid], C(30)H(42)N(2)O(4), contains a linear array of five six-membered rings and a five-membered heterocyclic ring. The C ring, containing an α,β-unsaturated ketone, has a slightly distorted half-chair conformation, as does the A ring, with N-C-C angles 125.3 (5), 111.2 (4), 124.9 (5) and 109.2 (5)°, while the ot...
The terpene and fatty acid composition in ethanol extracts of spearmint (lat. Mentha spicata) growing the Middle Urals was studied by gas chromatography chromatography-mass spectrometry. qualitative quantitative fraction depending on part plant (leaves, stems, roots) storage method (freezing, drying). 30 components were found extracts, 24 identified. It that greatest amount terpenes is containe...
We hypothesized that roasted Glycyrrhizae Radix (Glycyrrhizin Radix Praeparata, GRP) might modify anti-diabetic action due to compositional changes. Then we examined the anti-diabetic effect and mechanism of raw Glycyrrhizae Radix (GR) and GRP extracts and their major respective components, glycyrrhizin and glycyrrhetinic acid. In partial pancreatectomized (Px) diabetic mice, both GR and GRP im...
