The study aimed to evaluate extraction efficiency, detection and quantification of phytochemicals, minerals and antioxidative capacity of different parts of Salacia chinensis L. Continuous shaking extraction, steam bath assisted extraction, ultrasonic extraction and microwave assisted extraction with varied time intervals were employed for extraction of phenolics, flavonoids, and antioxidants. Preliminary screening revealed the presence of wide array of metabolites along with carbohydrates and starch. Steam bath assisted extraction for 10 min exposure was found most suitable for extraction phenolics (46.02 ± 2.30 mg of gallic acid equivalent per gram of dry weight and 48.57 ± 2.42 mg of tannic acid equivalent per gram of dry weight) and flavonoids (35.26 ± 1.61 mg of quercetin equivalent per gram of dry weight and 51.60 ± 2.58 mg of ellagic acid equivalent per gram of dry weight). In support, reverse phase-high performance liquid chromatography- diode array detector confirmed the presence of seven pharmaceutically important phenolic acids. Antioxidant capacity was measured by 1, 1- diphenyl-1-picryl hydrazyl (DPPH), ferric reducing antioxidant power (FRAP), 2, 2?-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) scavenging (ABTS) and N, N-dimethyl-p-phenylenediamine (DMPD) assays and represented as trolox equivalent antioxidant capacity (TEAC) and ascorbic acid equivalent antioxidant capacity (AEAC). Antioxidant capacity ranged from 121.02 ± 6.05 to 1567.28 ± 78.36 muM trolox equivalent antioxidant capacity and 56.62 ± 2.83 to 972.48 ± 48.62 muM ascorbic acid equivalent antioxidant capacity. Roots showed higher yields of illustrated biochemical parameters, however fresh fruit pulp was found a chief source of minerals. Gas chromatography-mass spectroscopic analysis revealed the presence of a vast array of phytoconstituents associated with different plant parts. The present study revealed the amounts of minerals and diverse phytoconstituents in various parts of S. chinensis and confirmed its medicinal and nutritional implications.

Reference of 22929-52-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.22929-52-8, Name is Dihydrofuran-3(2H)-one, molecular formula is C4H6O2. In a article，once mentioned of 22929-52-8

The first enantioselective organocatalytic a-allylation of cyclic ketones has been accomplished via singly occupied molecular orbital catalysis. Geometrically constrained radical cations, forged from the one-electron oxidation of transiently generated enamines, readily undergo allylic alkylation with a variety of commercially available allyl silanes. A reasonable latitude in both the ketone and allyl silane components is readily accommodated in this new transformation. Moreover, three new oxidatively stable imidazolidinone catalysts have been developed that allow cyclic ketones to successfully participate in this transformation. The new catalyst platform has also been exploited in the first catalytic enantioselective a-enolation and a-carbooxidation of ketones.

Cooperative functioning of the chiral Lewis acid and achiral Br°nsted base components gives rise to in situ enolate generation from monocarbonyl compounds. Subsequent reaction with hydrogen-bond-activated aldimines delivers beta-aminocarbonyl compounds with high enantiomeric purity.

Organic phosphonates and their derivatives are an important class of compounds in a variety of fields, especially medicinal chemistry, materials chemistry, agrochemistry and catalysis. For example, phosphonate esters and carbamoylphosphonates are matrix metalloproteinase (MMP) inhibitors, antimetastatic agents and antitumor agents. Phosphonate esters are usually prepared via a multistep transformation from a phenol and an organohalide and require toxic phosphorus halides and aryl/alkyl halides., Palladium-catalyzed couplings of an aryl halide (ArX) with a P?H compound, which were developed by Hirao and co-workers, are now typically used as efficient and substrate-tolerant methods for preparing phosphonates (Scheme 1)., Recently, great advances were made in the synthesis of phosphonate esters via metal-catalyzed C?P bonds couplings of H-phosphonates with C?X compounds (X=B, N, O, S and Si). Despite these clear advances, metal-catalyzed coupling reactions of P?H with C?X(H) are still limited by the need for costly noble metal catalysts. (Figure presented.).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 453-20-3 is helpful to your research. Related Products of 453-20-3
