The antidiabetic and antioxidant efficacy of traditional medicinal plants from North-Eastern India remains largely unexplored. This study seeks to address this gap by examining the properties of 11 such plants. The plant samples were subjected to extraction using four different solvents. Their antidiabetic potential was evaluated through in-vitro α-glucosidase and α-amylase inhibition bioassays, while the antioxidant activity was assessed using the DPPH Scavenging assay. The results were compared to the standard antidiabetic drug, acarbose. Out of the 11 plants, five species demonstrated significant antidiabetic properties, inhibiting more than 50% of α-glucosidase and α-amylase enzyme activities. The petroleum ether tuber extract of Stephania glandulifera exhibited the highest α-glucosidase inhibition (99%), followed by the methanol leaf extract of Begonia roxburghii (94%) and the water leaf extract of Antidesma acidum (85%). In the α-amylase inhibition assay, Equisetum debile methanol extracts showed a 64% inhibition, followed by the leaf extract of A. acidum with a 62% inhibition in the methanol leaf extracts. Comparatively, methanol and water leaf extracts of Debregeasia longifolia displayed 64%...

Objective: This study aimed to carry out a phytochemical, pharmacognostic, qualitative, and quantitative evaluation of the medicinal plant Psidium guajava L., also known as guava, a member of the Mytaceae family. Methods: The present study provides pharmacognostic, phytochemical, and quantitative details of Psidium guajava L. Results: Plant-dried stem powder material was subjected to continuous hot extraction Soxhlet using solvents pet-ether, acetone, and ethanol. Phytochemical standardization was undertaken to detect the presence of bioactive agents along with TLC. Different physical parameters, like ash values, extractive value, loss on drying, etc., were evaluated for the powdered drug. The extracts were obtained from the Soxhlet method and subjected to preliminary phytochemical evaluation. Conclusions: The results of this study can serve as a valuable source of information for identifying this plant for future investigation and...

The present study was conducted with an objective to evaluate the in-vitro antioxidant and hepatoprotective activity of three different medicinal plants. Due to the adverse effects of therapeutic agent with better hepatoprotective activity in modern medicine several plants have been screened for the aforesaid activity during last few decades detailed literature survey revealed that leaves of Aegles marmelos, Lawsonia innermis and Murraya koenigii plants were traditionally used for their liver protective activity. When healthcare providers refer to liver disease, they’re usually referring to chronic conditions that do progressive damage to your liver over time. Chronic liver diseases are not uncommon worldwide and are characterized by progressive evolution from steatosis to chronic hepatitis, fibrosis, cirrhosis and hepatocellular carcinoma. There is growing evidence that free radicals and reactive oxygen species play an important role in the progression of liver diseases and thus plants with free radical scavenging activity could play a crucial role in preventing the progression of liver disorders. The results of the present study demonstrate that, all 3 plants...

Amoxicillin Trihydrate is an extensively used antibiotic, and the accurate determination of its content in bulk and pharmaceutical dosage forms is of greatest importance. This thesis focuses on the development and validation of a High-Performance Thin-Layer Chromatography (HPTLC) method for the analysis of Amoxicillin Trihydrate. The study begins with an inclusive review of the existing analytical methods for Amoxicillin Trihydrate, highlighting the advantages and limitations of each technique. HPTLC is selected as the method of choice due to its simplicity, cost-effectiveness, and potential for routine analysis in pharmaceutical laboratories. The Chromatographic separation was carried out on Merck, Germany, TLC plates of silica gel 60 F254, 10 cm x10 cm using n-Hexane: ethyl acetate in the ratio of 7:3 (% v/v) as a mobile phase followed by densitometric measurements at 230 nm. The following method was validated in terms of accuracy, precision, linearity, limit of detection, limit of quantification, and specificity according to the ICH (International Conference on Harmonization) guidelines. The calibration curve and results were found to be linear...

Levodopa suffers from low oral bioavailability and less than 1% of the drug reaches the brain because of its peripheral degradation. This study aimed to prepare a nasal in-situ gel of levodopa and carbidopa to provide prolonged drug release, improve bioavailability, and increase drug uptake by the brain. Preliminary studies were carried out using different polymers. The concentration of polymer to be employed for the development of the formulations was deduced by carrying out placebo studies (F1-F12). All the batches were assessed for various parameters such as pH, viscosity, gelation time, and mucoadhesive strength. Out of 12 placebos, F11 which is pH and ion dual activated in-situ formulation showed satisfactory results. Therefore, F11 formulation was selected to prepare levodopa and carbidopa nasal in-situ gel. Drug incorporated formulation was found to have a viscosity of 2870.13 cps, assay of 95.7% of levodopa and 100.83% of carbidopa, and gelation time of 35 s, and the in-vitro drug release of levodopa and carbidopa after 8 h is 95.7% and 99.38%, respectively. Ex-vivo...
