Caryota urens (Palmae) is native to India. This tree species has been of interest to researchers because it is a medicinal plant employed in the indigenous Indian system of medicine. Pharmacognostic standardization, physic-chemical evaluation of the leaves of Caryota urens was carried out to determine its macro-and microscopical characters and also some insoluble ash and sulfated ash values, alcohol- and water-soluble extractive values were determined for phytochemical evaluations. Preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, leaf showed lamina, midrib regions, stomata. Powder microscopy showed mesophyll region, pitted xylem vessels and paracytic stomata. TLC of petroleum ether and ethanol extract showed three spots using hexane: ethyl acetate (12:4) and three spots using chloroform: ethyl acetate (5:4). Phytochemically leaves exhibited phytosterols, flavanoids, tannin carbohydrates, and phenolic...

This study was conducted to determine the in-vitro anti-microbial activity of Acacia etbaica, native plant to east African countries, against Staphylococcus aureus and Escherichia coli. To achieve this, the methanol extract of leaf of Acacia etbaica was tested for its in-vitro antibacterial activity against Staphylococcus aureus and Escherichia coli using agar disc diffusion method at two different concentrations (500 µg/disc and 1000 µg/disc). The minimum inhibitory concentration (MIC) of the plant crude extract was also determined using the microdilution method in 96-well plates. Acacia etbaica showed significant antibacterial activity with the mean zone of inhibition of 13.34 ± 1.04 mm and 11.13 ± 1.04 mm in diameter at a concentration of 1000µg of plant extract per disc against S. aureus and E. coli respectively. The MIC of the crude extracts of Acacia etbaica was determined to be 0.039 mg/ml and 0.313 mg/ml against S. aureus and E. coli respectively. The results suggest that the methanol extract of Acacia etbaica could be a rich source of antibacterial compounds. The results...

Several plants used for medicinal purposes can be found in the Brazilian Cerrado, among which highlights the genus Cecropia used as a bronchodilator, antitussive, anti-diabetic, anti-diarrheal, anti-hypertensive, anti-inflammatory and vasorelaxant. Between species, there is Cecropia pachystachya belongs to the Urticaceae family. This study aims to evaluate the phytochemical screening, antioxidant capacity and antimicrobial susceptibility of ethanol, aqueous and hydroalcoholic extracts the leaves of C. pachystachya extracts. In analyzing, the phytochemical screening was used for prospecting technique chemical constituents of plant extracts to detect the presence of alkaloids, anthraquinones, steroids/triterpenoids, flavonoids, glycosides, tannins, and saponins. The method of inhibiting free radical 2, 2-diphenyl-1-picrylhydrazyl (DPPH•) was employed for the evaluation of the antioxidant capacity of the extracts and the antimicrobial susceptibility wells technique in Mueller-Hinton agar. The ethanol extract showed better antioxidant activity compared to the control with 0.56 µL/mL of IC50, but also in antimicrobial susceptibility with inhibitory effect in different concentrations. We can conclude that the extract which showed a high performance against the trials was the ethanol. However,...

Since, ancient time, plants have been an exemplary source of medicine. Ayurveda and other Indian literature mention the use of plants in the treatment of various human ailments. Ficus benghalensis Linn is a large evergreen tree found throughout forest tracts of India. It is a popular indigenous system of medicine like Ayurveda, Siddha, Unani and Homeopathy. In the traditional system of medicine, various plants part such as stem bark, root bark aerial roots, vegetative bubs, leaves, fruits, and latex are used in dysentery, diarrhea, diabetes leucorrhoea, menorrhagia, nervous disorders, tonic and astringent. According to the ayurvedic system of medicine, Ficus benghalensis Linn. (Banyan tree) is well known to be useful in diabetes. The present review is, therefore, an effort to give a detailed survey of the literature on its pharmacognosy, phytochemistry, traditional and pharmacological...

Ocimum sanctum described as a sacred and medicinal plant in ancient literature, commonly known as Tulsi is derived from ‘Sanskrit,’ which means “the incomparable one.” This plant belongs to the family Lamiaceae which is native throughout the old world tropics and cultivated for religious and medicinal purposes. Several medicinal properties have been attributed to the plant not only in Ayurveda and Siddha but also in Greek, Roman, and Unani. It is widely known across South Asia as a medicinal plant and an herbal tea. Medicinal properties of Tulsi (Ocimum sanctum Linn.) are known for a thousand years to various civilizations of the world. This medicinal herb is considered as a sacred plant by the Hindus in the Indian subcontinent. Scientific explorations of traditional belief of medicinal properties of Tulsi have got momentum mostly after the middle of the 20th century. The wide numbers of phytochemical constituents have been isolated from the plant, e.g., aesculetin, orientin, vallinin, eugenol, alkaloids and is proved to have the potential for medical effects like...
