Cupressus macrocarpa (C. macrocarpa) is an evergreen tree with medicinal uses. The essential oil of C. macrocarpa possesses a powerful antimicrobial and antifungal effect against several bacteria and fungi. We aimed of this study to evaluate the antibacterial activity of C. macrocarpa. Fresh leaves of C. macrocarpa were collected and dried in the shade at room temperature. The essential oil was obtained using hydrodistillation, and yield was recorded. The antibacterial activity of the essential oil against Staphylococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris was examined, and minimal inhibitory concentration (MIC) was determined using a microdilution assay. As a result, the yield of essential oil from dried and fresh leaves was 0.39% and 0.4%, respectively. The MIC was 0.01 (v/v) for both Staphylococcus aureus and Proteus vulgaris, where the essential oil exhibited lower activity against Pseudomonas aeruginosa with a MIC of 0.04 (v/v). These results show the importance of using Cupressus macrocarpa essential oil to treat infection of several known resistant...

Carissa carandas Linn. is an evergreen plant of the Apocynaceae family. It is native to India and also found in Bangladesh, Sri Lanka, Indonesia, Malaysia, Pakistan, and Myanmar. Almost every part of these plants has been investigated for various pharmacological activities. Among all parts, leaves are less investigated. The present study explores the hepatoprotective activity of 60 % ethanolic extract of leaves of Carissa carandas Linn. Extraction of fresh mature leaves by the process of maceration using Petroleum ether gave 0.84 gm crude extract and a yield of 1.68 %. Extraction by using 60 % Ethanol gave 6.9 gm and a yield of 13.8 %. This crude extract was investigated for the evaluation of a hepatoprotective activity. The carbon tetrachloride (CCl4) induced method was used to study hepatoprotective activity. The extract showed significant dose-dependent hepatoprotective activity when compared with negative control group as the release of enzymes and bilirubin decreased with increasing dose of...

The study focuses on the green synthesis of silver sulfide nanoparticles using aqueous Senna occidentalis (L.) extract as reducing, capping, and stabilizing agents. Fourier Transform Infra-red Spectroscopy (FTIR) and Scanning electron microscopy (SEM) characterized the synthesized silver sulfide nanoparticles. FT-IR spectrum of Senna occidentalis leaves aqueous extract as shown in Fig. 3 below shows a number of peaks, thus reflecting its complex nature. The bands at 3175cm-1 is characteristic of the alcohol/phenol –OH stretching vibration, 2361.44cm-1 an attribute O=C= Stretching representing carbon dioxide. The weak peak at 1594cm-1 is assigned for C=O bending, indicating carboxylic acid, and the band at 995cm-1 represents the C=C bending signifying alkene. Fig. 4 below shows the FTIR result of the synthesized silver sulfide nanoparticle at different bands. The bands at 3785 and 3703 cm-1 correspond to O-H stretching vibration, indicating the presence of alcohol/phenol; the peak at 3406 cm-1 reflects N-H stretching of alphatic primary amine. Bands at 2919 and 2855.82cm-1 correspond to the C-H stretching of aromatic compounds. The band at 1713.88cm-1...

Vetiveria zizanioides (L.) Nash has been suggested in the Indian system of medicine as the roots of Usira for a number of diseases such as fever, dysuria, fatigue syndrome, wound healing, skin disorders, etc. (Jvara, Trishna, Mutrakrachhra, Vrana). This will be created helpfulness towards this medicinal plant and for preparation of different Ayurvedic formulations i.e Usira sava, Yogarajaguggulu, Sadanga Kvatha Curna. The objective of the present study is to develop the pharmacognostic and phytochemical profiles of Vetiveria zizanioides (L.) Nash root. The present study considers the detail investigation of macroscopy, microscopy, preliminary qualitative phytochemical analysis, physicochemical evaluations and HPTLC chromatography profiling. Microscopical investigation shows the presence of rectangular cells of epidermis, elongated and polygonal parenchyma groups, oval aerenchymatous cells, cork cells, elongated cells sclereids, sclerenchymatous stone cells, groups of sclerenchymatous fiber, prismatic crystals of calcium oxalate and starch grains. The presence of various secondary metabolites was confirmed by phytochemical screening and HPTLC profiling. Identification and authentication of roots may be helpful from botanical and chemical screening data for developing...

Using the plant as a source of medicine is one of the major campaigns in the field of alternative therapy. This study was conducted to investigate the antimicrobial activity of Leptadenia hastate root. The root of this plant was collected, dried, and ground. The powder was subjected to extraction by cold maceration using water and methanol. The in-vitro antimicrobial activity of the extract was tested against four strains of bacteria: Staphylococcus aureus, Pseudomonas aeruginosa, E. coli, Bacillus cereus and one fungus Candida albicans using the agar diffusion method. DMSO was used as a negative control; Ciprofloxacin was used as a positive control for bacteria and fluconazole as a positive control for fungi. The agar dilution method determined the minimum inhibitory concentration (MIC) of crude extract. The phytochemical analysis was conducted to determine the secondary metabolites. The antimicrobial activities show that methanol extract of Leptadenia hastate was only sensitive against Bacillus cereus and Candida albicans out of five organisms tested, while aqueous extract does not show activity against any organism...
