RESUMO

Human communities that inhabit the political borders live a transitional life, which is due to several socio-political and geo-climatic factors. The current cross-cultural ethnomedicinal study was conducted at the highly elevated Pakistan-India borders of the Western Himalayas in order to address the medicinal flora and folk knowledge of Balti and Shina communities. Ethnobotanical field surveys were conducted from May 2021 to September 2022. We used semi-structured interviews in order to collect the ethnomedicinal data. The collected data was analyzed using the relative frequency of the citations, use value, and Venn diagrams. A total of 140 interviews were conducted, which comprised of 90 (64.28%) Baltis and 50 (35.71%) Shinas. The interviews recorded 60 medicinal plant species that belong to 56 genera and 35 families. Asteraceae (5 spp.), Lamiaceae (5 spp.), and Apiaceae (4 spp.) were the families that were the most represented. These medicinally valued plants were being used for 55 health issues that are related to different body systems. Delphinium brunonianum, Thymus linearis, Hymenolaena candollei, Corydalis adiantifolia, and Seriphidium brevifolium were medicinal taxa with maximum RFCs and UV. The Baltis have comparatively more ethnomedicinal knowledge than the Shinas. The Baltis commonly used 22 (36.66%) species, which 34 (56.66%) were exclusive to the Baltis and 4 (6.66%) to the Shinas. Both ethnic groups collectively hold significant ethnobotanical knowledge that demands the preservation of risked folk knowledge, which is due to uncertain border situations, outmigration, and permeating allopathic drugs.

RESUMO

The process of washing and removing crude oil from spent catalysts is a serious issue in both catalyst regeneration and precious metals recovery. In this work, five different solvents with various polar and aromatic properties were chosen to evaluate their impact on the catalyst support structure and crude oil recovery from oil-contaminated spent catalysts. After the deoiling process, the spent catalyst was analyzed by scanning electron microscopy, X-ray diffraction (XRD), Fourier transform-infrared spectroscopy, elemental analyzer, contact angle measurement, gas chromatography-mass spectrometry, inductively coupled plasma-atomic emission spectroscopy, and Brunauer Emmet Teller (BET) method. Our findings demonstrate that p-xylene and kerosene are more effective in removing oil than other solvents. This is due to crude oil's similar polarity and molecular nature with kerosene and p-xylene. Considering the economical reason, kerosene is a better choice for deoiling spent catalyst compared to p-xylene as it is more affordable than p-xylene. XRD data show that the structure of the catalyst support was unaltered by the solvent treatment process, while BET data reveals that the surface area and pore volume are significantly enhanced after the deoiling process. These results imply that deoiling is a very crucial step for the recycling, regeneration, and reuse of spent catalysts. Our work is significant in developing sustainable approaches for managing spent catalysts, and minimizing waste and environmental pollution.

RESUMO

Convolvulus arvensis L. is an evergreen herb growing in various regions of Pakistan. Despite of several medicinal properties associated to this herb, it was not investigated scientifically for its bioactive compounds and detailed pharmaceutical properties. Therefore, its methanolic extract was divided into hexane (CA-H), chloroform (CA-C), ethyl acetate (CA-E) and butanol (CA-B) soluble fractions. CA-H and CA-C were found rich in phenolics (30.73±0.63 and 20.15±0.59 mg GAE/g of the extract, respectively), and the same fractions exhibited significant antioxidant activities (DPPH: 5.23±0.11 & 12.34±0.17 mg TE/g extract, respectively; ABTS: 36.82±0.04 & 56.74±0.61 mg TE/g extract, respectively). Also in CUPRAC activity assay, CA-H and CA-C exhibited highest activities as 87.30±0.46 and 56.74±0.61 mg TE/g extract, respectively, while CA-C was most active in FRAP activity assay with value of 40.21±2.19 mg TE/g extract. Total antioxidant capacity (1.23±0.033 mmol TE/g extract) was also found higher for CA-C, while CA-H activity was also comparable, however, CA-H showed higher metal chelating activity (22.74±0.001 mg EDTAE/g extract) than that of CA-C (17.55±0.22 mg EDTAE/g extract). These activities clearly revealed a direct relation between antioxidant potential and phenolic contents of CA-H and CA-C. In AChE and BChE inhibitory assay, CA-H and CA-E showed better inhibition (AChE: 8.24±0.77 & 4.46±0.007 mg GALAE/g extract; BChE: 5.40±0.02 & 1.92±0.24 mg GALAE/g extract) as compared to other fractions, whereas, against tyrosinase, CA-B was most active (37.35±0.53 mg KAE/g extract). CA-H and CA-C also showed higher inhibitory potential (0.98±0.08 & 0.58±0.01 mmol ACAE/g extract) against α-Amylase; while against α-Glucosidase, CA-E was the most active fraction. UHPLC/MS analysis of the methanolic extract of C. arvensis disclosed the presence of 62 compounds as sterols, triterpenes, flavonoids, fatty acids, alkaloids and coumarins. In Multivariate Analysis, the total phenolic contents were correlated strongly with all antioxidant assays except FRAP and DPPH. Regarding enzyme inhibitory properties, only AChE, BChE and α-amylase were correlated with the total phenolic contents in the extracts. Docking analyses confirmed these findings, as identified compounds had high binding free energy and inhibition constants with the enzymes studied. It was finally concluded that C. arvensis is a potential industrial crop, which can be a component of nutraceuticals and functional foods, if evaluated for its toxicity.

RESUMO

Ethnobotanical field surveys were carried out in the Tanawal area of the Lesser Himalayan Region, Khyber Pakhtunkhawa, Province from April 2016 to October 2017. The area is located between 34.36 (34° 21' 30 N) latitude and 73.07 (73° 4' 0 E) longitude with an average elevation of 1374 meters above sea level. Ethnomedicinal data were collected through Participatory Rural Appraisal (PRA), and participants were selected through the snow-boll technique. Semi-structured, in-depth and open-ended interviews were conducted. The data were quantitatively evaluated using ethnomedicinal indices i.e. Relative frequency of citation (RFCs), Fidelity level (FL), and Use Value (UV). The ethnobotanical data were also comparatively analyzed through the Jaccard Index (JI). The study yielded 66 medicinal plants in 62 genera and 43 families. Asteraceae and Solanaceae were the most important families with five medicinal taxa each. Regarding medicinal plant part utilization, leaves (43.28%) were used predominantly, followed by whole plant (14.92%) and fruits (14.92%). Decoction was the main drug formulation applied to 21 species (31.15%) and the oral route was most common (56.1%) while 31.2% of medicinal plants were used for both oral and topical applications. Fifty health disorders were recorded and grouped in 15 categories. Maximum species were used to treat gastrointestinal disorders i.e. 13 species, dermal problems (12 species), and respiratory tract ailments (9). The calculated RFCs ranged between 81 to 31. The most important medicinal plants were Acacia modesta, Citrullus vulgaris, Tamarindus indica, and Momordica charantia with an RGFC of 81 each. The UV ranged between 0.58 and 3.6. Medicinal taxa with the highest UV were Dioscorea deltoidea (3.6), Withania coagulans (3.3), Momordica charantia (3.5), Silybum marianum and Pyrus pashia (3.2). FL values showed that 28 (41.79%) species had a FL value below 50 (74.62%) while 39 (58.20%) had higher FL values. Momordica charantia, Tamarindus indica, Acacia modesta and Citrullus vulgaris were 95.2 each. The Jaccard Index (JI) values ranged from16.77 to 0.98. The current study also reported 16 medicinal plants, commonly used around the globe, have been rarely documented for their medicinal values in the local ethnomedicinal literature i.e. Althaea officinalis, Plantanus orientalis, Jasminum sombac, Maytenus royleana, Cucurbita maxima, Phyllanthus emblica, Citrullus vulgaris. Polygonatum verticilliatum, Caseria tomentosa, Cistanche tubulosa, Bambusa arundinacea, Schinus molle, Tamarindus indica, Pongamia pinnata, Citrus limon and Catharanthus roseus. However, 48 medicinal plants had been reported in the literature but the current study reported their novel medicinal uses. Important taxa should be established in botanical gardens for in-situ conservation, chemical investigation and sustainable utilization. It would also be effective to improve the livelihoods of the local population.

RESUMO

This study highlighted the taxonomic utilization of palynological metaphors for selected members (53) of family Poaceae. Multiple microscopic technique light and scanning electrons had been employed for detailed analysis. Results reported monad pollen type in all studied 53 members, which showed its limited taxonomic value up to family level. In relation to shape of pollen both polar and equatorial views strikingly differed from each other. Like semi angular pollen observed in Dactyloctenium aegyptium (L.) Wild. whereas round-minutely irregular pollen in Lolium temulentum L. Polar and equatorial diameter also showed variation, that is, Desmostachya bipinnata (L.) Stapf. can be differentiated from Sorghum bicolor (L.) Moench on diameter variation basis. A pore characteristic does not show much qualitative variation; however pore sizes differ species to species. The most frequently scarbate sculpturing was observed in 28 species followed by verrucate. Hence it can be said that pollen shape, polar, and equatorial diameters, pore size, P/E ratio, pore sculpturing are of good taxonomic value and holds a significant position in identification and delimitation of Poaceae taxa.

RESUMO

Traditional ecological knowledge, linguistic, and sociocultural perspectives are key contributors to environmental sustainability. Therefore, it is essential to identify and preserve this biocultural heritage, especially that of indigenous communities and minorities. We conducted an ethnobotanical survey to document the plant species used by the Balti and Shina communities living in the buffer zone of Deosai National Park (DNP), western Himalayas, Pakistan. A combination of random and purposive sampling techniques was adapted, targeting middle- and old-aged informants. A total of 46 semi-structured interviews were conducted and the gathered data were evaluated using relative frequency of citation (RFC) and through comparison with the ethnomedicinal literature. In total, 47 medicinal plant species belonging to 42 genera and 23 families were recorded. Baltis and Shinas cited 42 and 38 plant species, respectively, that were used to treat various diseases. About 60% of species were common among both communities, but 27.7% and 12.8% were exclusive to Baltis and Shinas, respectively. Considerable heterogeneity was noted in vernacular names, plant part(s) used, preparation, and administration. Ribes alpestre, Aconitum violaceum, Delphinium brunonianum, Thymus linearis, and Swertia petiolata were highly utilized species having RFCs > 50. In addition, 46% of medicinal uses, specifically that of Allardia tomentosa, A. tridactylites, Jurinea dolomiaea, and Gallium boreale, were reported for the first time from the region. Cross-cultural analysis revealed sociocultural gaps between both groups. Relatively, Baltis retained more ethnomedicinal knowledge and their traditional medicinal system is more closely associated with traditional Tibetan medicine. Generally, Balti and Shina communities retain substantial biocultural and ethnological diversity, which has been reflected in the present study. Our findings underline the importance and need for sustainable utilization of natural resources, specifically the plant species of this region. However, an in-depth ethnobotanical investigation may underpin the holistic comparative medical ethnobotany of the entire region.

RESUMO

BACKGROUND: The inhabitants of mountainous terrains depend on folk therapies to treat various ailments; however lack of plant based research and geographical constraints set the traditional knowledge in jeopardy. Present study is the first documentation on traditional uses of plant species by the inhabitants of the Shigar Valley, Karakorum Range, Northern Pakistan. METHOD: Ethnobotanical data were collected over a period from July, 2013 to October, 2016 from 84 respondents, using semi structured questionnaire. Quantitative indices such as relative frequency citation (RFCs) and fidelity level (FL) were intended to evaluate the importance of medicinal plant species. RESULTS: In total 84 plant species belonging to 36 families and 72 genera were recorded. Fabaceae was dominant with 7 species, followed by Asteraceae, Lamiaceae and Rosacea (6 species each). Leaves, root, flowers, seeds and fruits were the frequently utilized plant parts, whereas among drug formulations, decoction (49%) was ranked first. Majority of the plant species were used to treat abdominal, respiratory and dermal ailments (31, 12 and 12, respectively). RFCs value ranged 0.477 to 0.11 for Tanacetum falconeri and Allium carolinianum, respectively; while Hippophe rhamnoides and Thymus linearis depicted 100% FL. Comparative assessment with previous reports revealed that traditional uses of 26% plant species counting Hedyserum falconeri, Aconitum violoceum var. weileri, Arnebia guttata, Biebersteinia odora, Clematis alpine var. sibirica, Corydalis adiantifolia and Saussurea simpsoniana were reported for the first time. CONCLUSION: The endemic medicinal plant species and traditional knowledge of Balti community living in extremely high mountains area were explored for the first time. A comprehensive survey of this region could be significant to drive the existing knowledge in market circuit with sustainable collection, and to evaluate economic potential of the plant species. Additionally, social livelihood could be reinforced through establishing collection sites, transformation and drying centres for micro and macro marketing of medicinal plant species. Plants and people interaction in the Karakorum Mountains.

RESUMO

BACKGROUND: Limited health facilities and malnutrition are major problems in the Karakorum Range of Northern Pakistan, often resulting in various human disorders. Since centuries, however, local communities in these areas have developed traditional methods for treating various ailments and local foods capes that can be significant for devising public health and nutritional policies. This study was intended to document the ethnobotanical knowledge of the local peoples in the Tormik Valley, especially in the medical and food domains. METHODS: Field trips were undertaken in 14 different villages of the study area from 2010 to 2012. Ethnobotanical data were gathered using semi-structured interviews and group conversation with 69 informants. Details about local uses of plant species were recorded along with demographic characteristics of the visited communities. Relative frequency citation index (RFCi) and preference ranking index (PRi) tools were applied to determine the cultural significance of the reported species. RESULTS: Sixty-three plant species, with a predominance of Asteraceae and Fabaceae family members, as well as their detailed folk uses were documented. Forty-three percent of the species were used to treat various diseases, 21 % were consumed as wild fruits and vegetables and 53 % of the species had multipurpose applications. Thymus linearis Benth, Hippophae rhamnoides ssp. turkestanica L. and Convolvulus arvensis L. were found to be the most utilized medicinal plant species, i.e. those with significant RFCi values (0.54, 0.51 and 0.48, respectively). Betula utilis D. Don was the most versatile taxon (seven different ways of utilization); being this species a common and easily accessible subalpine tree and then under anthropogenic pressure, the implementation of concrete strategies aimed at its in-situ and ex-situ conservation is strongly recommended. CONCLUSION: The valleys in the Karakorum Mountains in the Northern Pakistan host significant Traditional Knowledge on local food and medicinal plant species, which need to be reconsidered and cautiously re-evaluated by ethnopharmacologists, and public health/nutrition actors. Furthermore, germane trans-disciplinary investigations are suggested to ensure the dynamic conservation of precious local knowledge systems, as well as plant diversity in Pakistani mountain regions.
