RESUMO
Investigation on medicinal plants' therapeutic potential has gained substantial importance in the discovery of novel effective and safe therapeutic agents. The present study is aimed at investigating the hepatoprotective potential of Seriphidium kurramense methanolic extract (SKM) against carbon tetrachloride- (CCl4-) induced hepatotoxicity in rats. S. kurramense is one of the most imperative plants for its various pharmacological activities. Therefore, this study was aimed at evaluating the hepatoprotective potential against CCl4-induced liver toxicity. The serum samples were analyzed for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) together with the oxidative stress mediator levels as nitric oxide (NO), malondialdehyde (MDA), glutathione (GSH), reduced glutathione (GSH), and superoxide dismutase (SOD) as well as peroxidation and H2O2 activity. CCl4 administration resulted in an elevated free radical generation, altered liver marker (AST and ALT) enzymes, reduced antioxidant enzyme, and increased DNA damage. Methanolic extract of S. kurramense decreased CCl4-induced hepatotoxicity by increasing the antioxidant status and reducing H2O2 and nitrate content generation as well as reducing DNA damage. Additionally, SKM reversed the morphological alterations induced by CCl4 in the SKM-treated groups. These results demonstrated that SKM displayed hepatoprotective activity against CCl4-induced hepatic damage in experimental rats.

In the current investigation, 16 samples of six species of the genus Polygonatum were collected from different geographical regions in China. Leaf micromorphological traits were studied in detail using scanning electron microscopy. About five-leaf samples were used for each species collected from different geographical regions. A significant variation was found in the foliar epidermal traits such as stomata types and their distribution, epidermal cell shape, anticlinal wall pattern, and various types of trichomes. Polygonal epidermal cells were observed in P. cyrtonema, P. odoratum, P. sibiricum, and P. filipes, rectangular in P. zanlanscianense and P. odoratum and irregular shape in P. filipes and P. zanlanscianense. Straight anticlinal wall pattern was observed in most of the species, but straight to little undulate was observed in P. cyrtonema, P. filipes, and P. zanlanscianense. Similarly, various shape stomata that are, oval, oblong, and elliptical and types that is, paracytic, anomocytic, and actinocytic have been observed. Based on the foliar traits, the P. odoratum and P. sibiricum were found closely related to one another. On the other hand, P. involucratum and P. zanlanscianense shows a strong association. However, P. filipes showed very less similarity with the other five species. Hence this study adds useful information that may be helpful in the further taxonomic classification of the taxa at subspecies level and was found significant in the correct identification and discrimination of the closely related taxa of the genus Polygonatum.

OBJECTIVE: Medicinal plants are used for treatment of ailments throughout rural and urban areas of the world. Such use of plants varies from one region to another and is measured using quantitative techniques. The current research which was conducted from March to October 2015, is the first explorative study of medicinal plants used by inhabitants of lower Kurram, Kurram agency, Pakistan. MATERIALS AND METHODS: Field trips were done to 20 location of lower Kurram and information regarding medicinal use of plants was collected from the locals through semi-structured interviews. RESULTS: A total of 52 plant species that were reported by the people from the region, to have medicinal value, fall within 48 genera and 35 families. The family Asteraceae comprised most of these herbs (6 species) followed by the family Lamiaceae (4 species) and Solanaceae (3 species). Leaves (24.3%) and fruits (21.6%) were the frequently used parts in preparation of remedies. The reported plants were used for treatment of 50 ailments with most of these plants (35 species; 30.97%) being used for treatment of digestive problems. Seriphidium kurramensis had the highest relative frequency of citation (66.18) and use value (1.10). Fidelity level of Caralluma tuberculata and Artemisia scoparia for diabetes was (61.22) and (55.56), respectively. The highest fidelity level for malaria was reported for Artemisia absinthium (43.66) and S. kurramensis (40.00). CONCLUSION: The inhabitants of lower Kurram still practice medicinal plants and few of the plants were used for treatment of fatal diseases like malaria, hepatitis and blood cancer. Haphazard cutting of plants and overgrazing are major threats that can affect plants biodiversity.
RESUMO
BACKGROUND: The residents of remote areas mostly depend on folk knowledge of medicinal plants to cure different ailments. The present study was carried out to document and analyze traditional use regarding the medicinal plants among communities residing in Koh-e-Safaid Range northern Pakistani-Afghan border. METHODS: A purposive sampling method was used for the selection of informants, and information regarding the ethnomedicinal use of plants was collected through semi-structured interviews. The collected data was analyzed through quantitative indices viz. relative frequency citation, use value, and family use value. The conservation status of medicinal plants was enumerated with the help of International Union for Conservation of Nature Red List Categories and Criteria (2001). Plant samples were deposited at the Herbarium of Botany Department, University of Peshawar for future reference. RESULTS: One hundred eight informants including 72 male and 36 female were interviewed. The informants provided information about 92 plants species used in the treatment of 53 ailments. The informant reported maximum number of species used for the treatment of diabetes (16 species), followed by carminatives (12 species), laxatives (11 species), antiseptics (11 species), for cough (10 species), to treat hepatitis (9 species), for curing diarrhea (7 species), and to cure ulcers (7 species), etc. Decoction (37 species, i.e., 40%) was the common method of recipe preparation. Most familiar medicinal plants were Withania coagulans, Caralluma tuberculata, and Artemisia absinthium with relative frequency (0.96), (0.90), and (0.86), respectively. The relative importance of Withania coagulans was highest (1.63) followed by Artemisia absinthium (1.34), Caralluma tuberculata (1.20), Cassia fistula (1.10), Thymus linearis (1.06), etc. This study allows identification of novel uses of plants. Abies pindrow, Artemisia scoparia, Nannorrhops ritchiana, Salvia reflexa, and Vincetoxicum cardiostephanum have not been reported previously for their medicinal importance. The study also highlights many medicinal plants used to treat chronic metabolic conditions in patients with diabetes. CONCLUSIONS: The folk knowledge of medicinal plants species of Koh-e-Safaid Range was unexplored. We, for the first time, conducted this quantitative study in the area to document medicinal plants uses, to preserve traditional knowledge, and also to motivate the local residents against the vanishing wealth of traditional knowledge of medicinal flora. The vast use of medicinal plants reported shows the significance of traditional herbal preparations among tribal people of the area for their health care. Knowledge about the medicinal use of plants is rapidly disappearing in the area as a new generation is unwilling to take interest in medicinal plant use, and the knowledgeable persons keep their knowledge a secret. Thus, the indigenous use of plants needs conservational strategies and further investigation for better utilization of natural resources.
