Objective: To study the acute oral toxicity of ethanolic extract of Actinoscirpus grossus (L.f.) Goetgh. and D.A. Simpson in Wistar albino rats.Methods: Ethanolic extract of the plant was assessed for single dose acute toxicity by employing Organisation for Economic Co-Operation and Development(OECD) guidelines 425 using Acute Oral Toxicity(AOT) software. The dosed (up or down as per the requirement) rats were observed for 14 days for general appearance, behavior, mortality, and necropsy. A total of 5 healthy female rats of body weight 225±25 g were used.Results: The test substance did not produce any mortality up to the dose of 2000 mg/kg per oral.Conclusion: Test substance is without any toxic potential even at the dose of 2000 mg/kg in animals and the Lethal Dose (LD50) value of A. grossus (L.f.) Goetgh. and D.A. Simpson was found to be more than 2000 mg/kg body weight.

Actinoscirpus grossus (L.f.) Goetgh. & D.A.Simpson (Cyperaceae), is a Perennial with long stolons and rhizomes ending in small tubers. It is popularly known as Kasheruk in Sanskrit. The plant is traditionally used as anti-diarrheal, anti-emetic, and tonic to the liver. In order to do the detail standardization of plant macro-microscopical observation, phytochemical analysis and HPTLC Finger printing of tuber was performed according to pharmacopoeia procedure. Microscopic analysis has showed thick-walled polygonal epidermal cells of young root stalk in surface view, elongated phloem parenchyma filled with starch grains, spiral to annular vessel fragments and simple starch grains scattered all over the powder. Phytochemical analysis showed presence of carbohydrate, coumarins, flavanoids, steroid, tannin, and terpenoid. Ethanol extract of plant were fingerprinted in toluene: ethyl acetate (7:3). The developed plates were visualized in UV 254, 366, and then derivatised with vanillin sulphuric acid and scanned under UV 254 and 366 nm. These specific identities will be useful in identification and authentication of the raw drug.

This research objective is for the development of a specific and simple method to trace Semaglutide presence in active pharmaceutical ingredient and pharmaceutical dosages. As part of a study on Semaglutide drug, solvents of HPLC grade waters HPLC instrument (Empower software) with PDA detector, ultrasonicator (Make: Labman) and pH meter (Make: Adwa) are used. The Method was optimized with mobile phase with a composition of buffer and solvent were of 60:40%v/v, flow maintained was 1.0ml/min, the injection volume of 10µl, run time was 5min. All separations were performed with PDA detector and column used was Discovery C18 150 x 4.6mm, 5m. Results for the developed method are accurate and specific. The detection wavelength was 292 nm, the retention time for Semaglutide was 2.689min, linearity resulted with r2= 0.9998, % RSD for precision was 1.0; %mean recovery for accuracy was in the range of 99.73 to 100.29.  This study report is for industrial application for determining Semaglutide presence in pharmaceutical ingredient and dosages.
