The purpose of this study was to substantiate the use of suspension of Chlorella genus microalgae as the most valuable raw material for the preparation of carotene and chlorophyll а. The method is proposed for ultrasonication of Chlorella vulgaris microalgae suspension to increase the availability of biologically active substances and improve the microbiological performance of the prepared product. Before and after ultrasonication of samples, we determined the content of chlorophylls (a, b, c) and carotenoids using the spectrophotometric method, the level of total bacterial contamination using the method of limiting dilutions on MacConkey agar and microscopic study of microalgae and bacteria cell viability. It has been established that the ultrasonication method at wave amplitude 16 µm allows to transfer pigments into the water phase, inhibit the viability of bacteria and obtain homogenization of the Chlorella vulgaris microalgae suspension with preservation of carotenoids and green chlorophyll а. Thus, the combined use of ultrasonication and parallel plating on MacConkey agar seems to be promising given preparation and quality control of axenic...

India is well known as the emporium of medicinal plants harboring many plants of medicinal importance, of which Curculios orchioides is one that has been reported to possess medicinal importance for the treatment of various diseases traditionally as well as scientifically. An attempt was made herein to undertake a detailed pharmacognostical and preliminary phytochemical investigation of the root tubers of Curculigo orchioides Gaertn. for the first time. The pharmacognostic study comprises of the taxonomical characters of the root tubers of Curculigo orchioides, histochemical tests, and diagnostic characters. The phytochemical analysis consists of the determination of physicochemical constants, fluorescence analysis, and preliminary organic analysis. The diagnostic characters of the plant showed that the leaves are radical with parallel venation while flowers are solitary, trimerous, and ovary inferior. These parameters help in the standardization of the crude drug and in formulating Pharmacopoeial standards for the crude drug. Preliminary phytochemical screening of the crude drug showed the presence of carbohydrates and glycosides, phytosterols, fixed oils and fats, phenolic compounds and tannins, saponins,...

Aim of study: Compare the study on physio-chemical parameters of Acacia arabica and Prosopis juliflora. Material and Methods: The ethanolic extract of on Acacia arabica and Prosopis juliflora were using physio-chemical parameters and preliminary phytochemical investigation. Results and Discussion: In this study. I have done the comparative pharmacognostic study on Acacia arabia and Prosopis juliflora and conclude that the ethanolic extract of Acacia arabica plays a more significant role and has more significant value than the extract of Prosopis juliflora. Conclusion: The present study was aimed at the pharmacognostical study. Plants Acacia arabica and Prosopis juliflora were studies for pharmacognostical characteristic, namely, morphology, microscopy, which can be of utilized in identification and authentication of the...

Objective: To study detailed pharmacognostic profile and preliminary phytochemical investigation of the leaves of Indigofera tinctoria Linn. commonly known as ‘indigo’ belongs to the family Fabaceae. It is distributed through the hotter parts of India. Medicinal uses include the juice of the leaves as a prophylactic against hydrophobia, and as a decoction for blennorrhagia; plant extract as the treatment for epilepsy, nervous disorders, bronchitis, and as an ointment for sores, old ulcers, and hemorrhoids; and roots for hepatitis, scorpion bites, and urinary complaint. Methods: Leaf of I. tinctoria Linn. was studied by macroscopical, microscopical, quantitative microscopy, physicochemical, phytochemical analysis of leaf powder of the plant and other methods for standardization recommended by WHO. Results: Macroscopically the leaves with 9-13 leaflets and broken pieces of rachis, opposite, oblanceolate with very short mucronate tip, pale greenish black, mucronate apex, cuneate base, smooth texture, characteristic odor and taste. Leaflets 1-2.5 cm long and 0.3-1.2 cm wide. Microscopically, the leaflet appears wavy in T.S. view; prominent adaxial and abaxial thickening, the vascular bundle...

Azadirachta indica (A. indica) belongs to the family Meliaceae. Various parts of the plant, including root, are used as a drug for various ailments, including malaria. The purpose of this study was to determine the chemical composition of essential oil (EO) of the root of A. indica collected from North Central Nigeria. The root essential oil of Azadirachta indica was obtained by using hydrodistillation method. Gas Chromatography, coupled to mass spectrometry, was used to analyze and determine the chemical composition of the essential oil. Mass spectra were searched against Mass Spectrometry databases, and twenty-eight components were identified. The main constituents citronellic acid (29.60%), 1-bromotriacontane (8.59%), totara-8,11,13-triene-7.beta.,13-diol (8.26%) and 4,8,12,15,15-pentamethyl-bicyclo[9.3.1]pentadeca-3,7-dien-12-ol...
