Curcuma albiflora Thw. is an important anti-inflammatory medicinal plant, which is used in Sri Lankan Traditional Medicine. The plant is endemic to Sri Lanka and unexplored. Therefore it is necessary to conduct a proper systematic study to establish a chemical profile of C. albiflora. Therefore, the current study was conducted GC-MS study on various extracts of C. albiflora. The whole plant parts of the plant C. albiflora were collected from June to October in the flowering season at Sabaragamuwa province, Sri Lanka. Samples were authenticated by National Herbarium, Peradeniya. Hydro-distillation by Clevenger’s apparatus and continuous extraction by Soxhlet apparatus were carried out on various solvents (petroleum ether, acetone, and methanol). GC-MS analyses were performed on various extracts (water, petroleum ether, acetone, and methanol) of C. albiflora. Retention index was calculated of each compound based on standard alkane chromatogram. The whole plant of C. albiflora essential oil consisted mainly of α-pinene (14.51%), caryophyllene oxide (9.35%), alcanfor (5.12%), aromadendrene oxide-I (4.81%), α-famesene (4.01%) and camphene (3.64%). While petroleum ether extract of...

Honey is commonly used by the indigenous population in Brazil due to its large variety of physiological properties such as ulcers and dermatitis healing. The goal of this paper is to select and to test different types of Brazilian honey to be used associated with Aloe vera as an accessible wound treatment. Three types of honey were analyzed: two produced by Tetragonisca angustula in different regions of Brazil and one honey produced by Apis mellifera scutellata, associated with both water and Aloe vera. Quantitative assays, where bacterial growth curve was analyzed by optical density, were performed to test the antimicrobial activity of the samples. From the results obtained, we observed that the three types of honey studied presented a satisfactory antimicrobial activity. The association between honey and Aloe vera, besides demonstrating better antimicrobial action than each compound itself, it demonstrated better effectiveness against Enterobacteriaceae species (E. coli and S....

Portulaca quadrifida Linn. (Portulacaceae) is commonly known as a chicken weed in English. In the traditional system, it is used to treat rheumatism and gynecological diseases, urinary tract infections, worm diseases, dysentery and dermatitis. To assess the cytotoxic potential of hydroalcoholic extract of P. quadrifida leaves using brine shrimp assay. Potassium dichromate was considered a standard reference drug. The concentrations of 10, 100, 1000 μg/ml were used in the experiment. The mature shrimps were taken, and it was treated with the extract and the standard in the respective concentrations. LC50 value was calculated for both standard and extract, and the probit analysis was made by using SPSS software. From the probit analysis, the cytotoxicity of the extract was determined by comparing it with the standard. The graph was plotted for both the standard and the extract; the extract was found to be non-...

Unprecedented growth in popularity of complementary medicines raised concerns about their quality and safety. So, there is a need to develop methods for their sensitive, specific and accurate analysis. Authenticity and similarity of medicinal nutrients and strict procedures of material handling are significant features to maintain the quality of herbal preparations. Genome-based methods to authenticate these plants revolutionized the authentication process. Developing DNA molecular markers by sequencing a standard zone of the DNA is the best technique to identify the adulterants as well as to authenticate the required species of medicinal plants. Application of molecular biological technique serves as one of the very consistent systems for authentication of natural herbal materials. The progress of authentic analytical methods is a major challenge to scientists as natural products are optimized as drug-like molecules. Current work is based on the use of PCR technique for authentication of Glycyrrhiza glabra L. standard crude root and in polyherbal formulations i.e., Hamdard’s Joshanda, Marhaba’s Joshanda, GNC Herbal supplement and Joshaba Sadar (Chest Tea) available in...

Objective: To study detailed pharmacognostic characters of the stem of Nyctanthes arbor-tristis (Oleaceae), along with their physicochemical parameters, fluorescence analysis, and phytochemical screening. Methods: The pharmacognostic characters were determined in terms of macroscopy, microscopy, powder microscopy, physicochemical analysis, fluorescence analysis and preliminary phytochemical investigation of the plant stem. Results: The microscopic study shows the general characteristic of the stem. Physico-chemical investigation shows the total ash, acid insoluble ash, water-soluble ash were 8.69 ± 0.17% w/w, 0.21 ± 0.11% w/w, and 3.92 ± 0.05% w/w respectively. Phytochemical analysis revealed the presence of various phytochemical groups like alkaloids, glycosides, steroids, phenolic, tannins constituents. Conclusion: It can be concluded that the established pharmacognostic profile of Nyctanthes arbor-tristis stem will help develop pharmacopoeial standards for correct identification and quality...
