The applications of the seed oil are defined by its quality through many factors, including seed origin. The study aims to investigate the physicochemical characteristics to compare the oil quality of plant Azadirachta indica (Family: Meliaceae), grown in different geographical areas, Malaysia, and Sudan. Oils were extracted through the Soxhlet method via hexane for the duration of 6 h. The characteristics of the oils from Malaysia (OMY) and Sudan (OSD) are; lipid content: 37.03 and 39.96%; physical state: liquid for both; color: greenish-brown and brownish-yellow; odor: peanut with garlic and only peanut; density: 0.95 and 1.06 g/cm3; refractive index: 70.90 and 69.80; pH: 4 and 5; moisture & volatile matter: 0.83 and 0.07%; acid value: 4.80 and 6.37 mg KOH/g; iodine value: 93.09 and 63.81 gI2/100g; peroxide value: 8.49 and 1.67 meq O2/kg; unsaponifiable matter: 1.84 and 0.91%; and free fatty acid: 4.75 and 3.21%. OMY and OSD recorded eight similar fatty acids: oleic- 20.46 and 52.02%, linoleic- 34.69 and 3.02%, stearic- 20.42 and 18.79%, palmitic- 18.66 and 20.79%,...

About 80% of the population living in rural areas in developing countries depends on traditional medicine for their health care needs. Many of the powerful drugs used in modern medicines originated in plants. Today’s plant-based drugs treat a range of diseases, from headaches to cancer. The objective of the present study was to evaluate phytochemical, antioxidant potential, and cytotoxicity of methanolic extract of leaves of Trapa bispinosa Roxb. The phytochemical screening demonstrated the presence of carbohydrates, glycosides, alkaloid, saponins, and tannins. Total phenolic and flavonoid content of the Trapa bispinosa Roxb. extracts was determined by using the Folin- Ciocalteu reagent and aluminum chloride (AlCl3) method, respectively. Antioxidant activity was evaluated by using 1, 1-diphenyl-2-picryl-hydrazil (DPPH) free radical assay. In DPPH assay, free radical scavenging activity of the extracts was evaluated comparing with ascorbic acid at the wavelength of 517 nm and the IC50 value of Trapa bispinosa Roxb. extracts were found to be 1.58 µg/ml, whereas ascorbic acid showed the value of 1.129 µg/ml. Moreover, it showed moderate reducing...

Siddha is one among the ancient systems of Indian medicine. Its reliability lies in the fact that it is time-tested, devoid of any drastic adverse effects and deep-rooted in the culture and heritage of India. The role of this system in treating chronic diseases is being widely felt nowadays. The challenges in treating such conditions with the currently available drugs (Non-Steroidal Anti-inflammatory Drugs – NSAID) often results in gastric irritation, renal damage, dependence, etc. Traditional Siddha medicines offer a wide range of Anti-inflammatory drugs which are polyherbal in nature and devoid of the above-said side-effects 1. This paper deals with Anti-inflammatory screening of such a medicine ‘Ashwathi chooranam’ documented in Classic Siddha text “Agathiar Vaithiya Kaaviyam” indicated for arthritis 2. Withania somnifera (Ashwagandha) is widely used in Siddha medicine. It is the main ingredient in many formulations prescribed for a variety of musculoskeletal conditions (e.g., arthritis, rheumatism), and as a general tonic to increase vitality, improve overall health and facilitates longevity 1. In our study, we reproduced an inflammatory...

A series of 1-(2-(4H-1,2,4-triazol-4-yl)ethylamino)-3-ch-loro-4-(5-methoxy/ehthoxy-2-substituted alkyl/aryl-1H-indol-3-yl)azeti-dinones (4a-4h) and 1-(2-(4H-1,2,4-triazol-4-yl) ethylamino)-3-chloro-4-(5-methoxy/ethoxy-2-substituted alkyl/aryl-1H-indol-3-yl) thiazolidi-nones (5a-5h) have been synthesized by the reaction of 3-((2-(2-(4H-1,2,4-triazol-4-yl)ethyl)hydrazono)methyl)-5-methoxy/ethoxy-2-substi-tuted-1H-indoles (3a-3h) with chloroacetyl chloride and thioglycolic acid respectively. All the newly synthesized compounds were screened for their antibacterial activity against S. aureus, E. coli, P. vulgaris, K. pneumonia and antifungal activity against A. fumigatus, C. albicans, C. albicans ATCC and C. krusei G03. The antibacterial activity of newly synthesized compounds compared with standard drug gatifloxacin and ciprofloxacin against different bacteria and antifungal activity of new compounds compared with standard drug fluconazole against different fungi. The compounds 5d, 5e, 5g, and 5h exhibited good antibacterial activity while compounds 4g, 5g, and 5h also showed notable antifungal activity. The purity of the newly synthesized compounds was checked by thin-layer chromatography (TLC) on silica gel-G coated plates using different solvent systems. The structure of all the compounds was established by the elemental (C, H, N) and spectral (IR, 1HNMR, and mass)...

Loratadine a long-acting tricyclic antihistamine with selective peripheral histamine H1-receptor antagonistic activity, is used for the symptomatic relief of allergic conditions like runny nose, itchy or watery eyes, sneezing and nasal or throat itching and chronic urticaria. It is stable in acidic pH, has a narrow therapeutic absorption window in the GI tract and found to be absorbed in the proximal part of the small intestine. Thus, it is decided to prolong the gastric residence time in terms of making floating gastro retentive drug delivery system to increase drug absorption and hence bioavailability. In this study, Loratadine floating tablets were prepared by using HPMC K15 M and Sodium Alginate as polymers and gas generating agents like sodium bicarbonate and calcium carbonate at varying polymer concentrations and combinations. The tablets prepared by direct compression technique were evaluated in terms of their pre-compression parameters and post-compression characteristics such as physical characteristics, total buoyancy, buoyancy lag time, swelling index, and in-vitro release. The best formulation showed no significant change in physical appearance,...
