Triphala is a traditional Ayurvedic herbal formulation consisting of dried pericarp of three medicinal plants Terminalia chebula Retz., Terminalia bellerica Roxb. and Emblica officinalis Gaertn. Masi (Black ash) prepared from this combination is of great use. No pharmacognostical profiles are available on Triphala Masi till date. So the same is attempted in current study. Aim: To evaluate pharmacognostical profiles of Triphala Masi prepared at three different levels of temperature. Materials and Methods: Tripahla Masi was prepared at three different levels of temperature and samples were coded as TM 1, TM 2 and TM 3 and further subjected for pharmacognostical profiles. Results: Loosened walls of epicarp cells were observed in TM 1 sample prepared at 3000C; showed that these cells sustained up to this temp. At 3500C, epicarp cells in the sample TM 2 were seen disturbed. But when heat was increased up to 4000C, only black mass was observed in TM 3 sample. Conclusion: Based on pharmacognostical observations, 4000C temperature is required for preparation of Triphala Masi.

Abstract: The study were conducted at Dilla University, College of Natural Sciences, Biological Sciences laboratories. Background: Ethiopia is a country with many ethnic groups, cultures and beliefs which in turn have contributed to the high diversity of traditional health care knowledge and practices of traditional medicine from local growth plants, animals and minerals for various physical and mental disorders of human and livestock population that passed from generation to generation for centuries. Medicinal plants contributors to pharmaceutical, agricultural and food industries in the world. The use of medicinal plants in the industrialized societies has been traced to extraction and development of several drugs used in order to heel some diseases having inhibiting effect against pathogenic microorganism. Objective: The main objective of this study was Extraction and Phytochemicals determination of traditional medicinal plants for anti microbial susceptibility test. Methodology: The extraction and identification of some phytochemicals crude compound which used for antimicrobial susceptibility test from plant sample such as Ocimum lamiifolium (OL), Croton maerosth (Cm) and Ruta chalepesis (RC) were conducted. Plant samples are collected, powdered using mortal and pistil and extracted using ethanol and some susceptibility tests were performed to identify some phytochemicals compound. Result: The main result of Antimicrobial activity test showed that the crude extract of OL has the highest zone of inhibition. The highest yield of crude extract (38.21%) was obtained from Croton maerosth (CM) which followed by Ruta chalepesis (RC) (32.43%). However, the lowest yield (28.37%) was obtained from Oscpmum lamifolium (OL). Conclusion: Traditional Medicine is used by many people to managing numerous conditions; it’s accessible and effective on antimicrobial activity. Therefore, it plays a significant role by reducing life-threatening ailments of people and other animals.

Background: Emblica officinalis Gaertn. which belongs to the family Euphorbiaceae, Terminalia chebula Retz. and Terminalia bellerica Roxb. belong to the family Combretaceae. These are well known medicinal plants with phytochemical reservoir of great medicinal values and possess a vast ethnomedical history. Objective: The aim of the present study is to isolation of major compounds and to evaluate antimutagenic potential of the ethanol extracts of these plants. Methods: The dried fruits of E. officinalis, T. bellirica and T. chebula were powdered and extracted with 95% ethanol. The ethyl acetate portions were chromatographed over silica gel to isolate major compounds. Antimutagenic activity was determined by Ames test using TA98 and TA100 strains of Salmonella typhimurium. Results: Two major known compounds, gallic acid and ellagic acid were isolated from the dried fruits of Emblica officinalis, Terminalia chebula and T. bellirica. All the three extracts counteracted the mutagenicity induced by different genotoxic compounds in a dose dependent manner. Conclusion: This study showed that ethyl acetate portion of three extracts contain two major compounds, gallic acid and ellagic acid which might be responsible for potent antimutagenic activity of these extracts.

Rhus coriaria L. (Anacardiaceae), commonly known as sumac, is a commonly used spice, condiment, and flavoring agent, especially in the Mediterranean region. Owing to its bountiful beneficial values, sumac has been used in traditional medicine for the management and treatment of many ailments including hemorrhoids, wound healing, diarrhea, ulcer, and eye inflammation. This plant is rich in various classes of phytochemicals including flavonoids, tannins, polyphenolic compounds, organic acids, and many others. By virtue of its bioactive, Rhus coriaria possesses powerful antioxidant capacities that have ameliorative and therapeutic benefits for many common diseases including cardiovascular disease, diabetes, and cancer. This review describes the phytochemical properties of R. coriaria and then focuses on the potent antioxidant capacities of sumac. We then dissect the cellular and molecular mechanisms of sumac’s action in modulating many pathophysiological instigators. We show how accumulating evidence supports the antibacterial, antinociceptive, antidiabetic, cardioprotective, neuroprotective, and anticancer effects of this plant, especially that toxicity studies show that sumac is very safe to consume by humans and has little toxicity. Taken together, the findings we summarize here support the utilization of this plant as an attractive target for drug discovery.

Abstract The aim of the study was to develop a rapid, efficient, and cheap chromatographic method for determining four selected antihypertensive active flavonoid compounds in medicinal plants in Botswana. The determination of rutin, quercetin, and kaempferol in selected medicinal plants was conducted in less than 6 min using the developed reverse phase-high performance liquid chromatography (RP-HPLC) method with a 2.7 µm Ascentis C18 express column (150 × 4.60 mm i.d) at 340, 360, and 368 nm detection wavelengths and mobile phase of methanol and 0.068% of formic acid solution in isocratic elution. Validation results showed good selectivity, linearity (r 2 > 0.99), high percentage recoveries (90.2–104.7%), and precision (% RSD < 2) for n = 3, confirming suitability of the method for determination of the investigated flavonoids in Zingiber officinale (ginger). Application of the developed RP-HPLC method was performed in selected medicinal plants (Lippia javanica ) (mosukujane), Myrothanmus flabellious (galalatshwene), and Elephantorrhiza elephantina (mositsana) used to manage hypertension by herbalists in Botswana. M. flabellious a very commonly used plant for managing hypertension was found to contain highest amounts of rutin and myricetin, whereas nothing was detected for E. elephantina.
