Traditional Knowledge on Ethnobotanical Uses of Plant Biodiversity: a Detailed Study from the Indian Western Himalaya Biodiv. Res.

[email protected] Abstract: The present article is based on the findings of ethnobotanical surveys conducted in the entire Lahaul-Spiti region of Indian western Himalaya to highlight the traditional use of medicinal plants by the native people. Results revealed that tribal communities of both Lahaul and Spiti valleys (Lahaulas in Lahaul and Bhotias in Spiti) have a great respect for and faith in Amchi system of medicine practiced in the entire region. Information collected on the traditional use of plants in the local health care system by the tribal communities of Lahaul-Spiti revealed the use of 86 plant species belonging to 69 genera and 34 families to cure about 70 different ailments. Maximum number of plant species used in herbal formulations belonged to families Asteraceae, Apiaceae, Gentianaceae, and Polygonaceae. Both single herbal preparations and polyherbal formulations are prescribed and administered by local healers known as Larje in Lahaul and Amchis in Spiti. Most of the medicines are prescribed in a powder form, some as juice and decoctions. Among plant parts, leaves were recorded to be used to a large extent as a remedy, followed by flowers. Results of the present study show that the highest number of plants was used to cure stomach disorders, while the highest extent of phytotherapeutic use among all the species had Hippophae rhamnoides (17.14%). The obtained data also revealed the information on new or less known medicinal uses of various plant species that are new addition to the traditional knowledge from western Himalaya. Modes of preparation, administration and dosage are discussed along with the family and local names of plants and plant parts used.

  • Comparative Foliar Micromorphological Studies of Some Species of Asteraceae from Alpine Zone of Deosai Plateau, Western Himalayas
    Bano et al., The Journal of Animal & Plant Sciences, 25(2): 2015, Page:J.422 Anim.-430 Plant Sci. 25(2):2015 ISSN: 1018-7081 COMPARATIVE FOLIAR MICROMORPHOLOGICAL STUDIES OF SOME SPECIES OF ASTERACEAE FROM ALPINE ZONE OF DEOSAI PLATEAU, WESTERN HIMALAYAS A. Bano, M. Ahmad, M. Zafar, S. Sultana and M. A. Khan Department of Plant Sciences, Quaid-i-Azam University Islamabad Pakistan Corresponding Author e-mail: [email protected] ABSTRACT This study concerns the evaluation of foliar epidermal anatomical characteristics of twelve species of Asteraceae by light microscopy (LM). The plant materials were collected from various localities of Deosai plateau. Three stomata types including anisocytic, actinocytic and anomocytic have been found in the family. Stomata type is Anisocytic in Artemisia persica, Actinocytic in Circium falconerii and Erigeron multiradiatus while anomocytic in rest of the nine species. The stomata type seems to be constant character at genus level. Leaf epidermal features like shape of epidermal cells and trichomes are found useful taxonomic tools. The epidermal cells were irregular or polygonal with straight or undulate walls. Two species of Saussurea viz., Saussurea nepalensis and S. obvallata are distinguishable on the basis of shape of epidermal cells. The pattern of walls is similar on both abaxial and adaxial sides in all species except in Senecio chrysanthemoides where it is weakly undulate on abaxial side and heavily undulate on adaxial side. The diversity in the foliar trichomes is of taxonomic importance for discrimination of taxa at specific level. Artemisia persica was unique in being the only species with stellate trichome. Aster himalaicus can be delimited from other species by the possession of J-shaped trichomes while long multicellular trichomes were found in Conyza japonica and Senecio chrysanthmoides.

  • Classification of Subtribe Conyzinae (Asteraceae:Astereae)
    8 LUNDELLIA DECEMBER, 2008 CLASSIFICATION OF SUBTRIBE CONYZINAE (ASTERACEAE:ASTEREAE) Guy L. Nesom 2925 Hartwood Drive, Fort Worth, Texas 76109, USA Abstract: Subtribe Conyzinae includes Erigeron, New World Conyza, the North American genus Aphanostephus, and a small group of South American species segregated as the genera Apopyros, Darwiniothamnus, Hysterionica, Leptostelma, and Neja. Erigeron is the only genus with species native to regions outside of the New World. About 500 species are included in the subtribe. All North American, Central American, and South American species of Erigeron are included in the present treatment and assigned to one of the 35 sections recognized here. Ten new sections of Erigeron are recognized: sect. Disparipili, sect. Filifolii, sect. Gyrifolium, sect. Lonchophylli, sect. Meridionales, sect Microcephalum, sect. Quercifolium, sect. Radicati, sect. Rhizo- nexus, and sect. Terranea. Conyza is at least biphyletic; each of the groups is represented in the treatment but not all of the South American species are included. Molecular data have made it clear that traditional, North American species of Erigeron form the basal and terminal clades in the evolutionary topology of the subtribe, thus Conyza, Aphanostephus, and the other segregate genera have arisen from within the branches of Erigeron. Erigeron, as currently treated and tentatively maintained here, is paraphyletic. Broad taxonomic alternatives that include only monophyletic taxa are: (1) to treat the whole subtribe as Erigeron or, (2) to recognize Aphanostephus or Aphanostephus, Conyza, and the other South American segregates and at least an additional 5 to 10 new generic-level segregates from species groups traditionally treated as North American Erigeron. Keywords: Compositae, Conyza, Erigeron.

In this study, area under investigation was divided into 33 stands on the basis of physiognomic characteristics of the vegetation. A total of 105 plant species of 55 families were recorded. The leaf size spectra was dominated by Microphyll contributing 68 species, followed by Mesophylls 45 species, Nanophyll 41 species, Macrophyll and Leptophylls l7 species. Therophytes were found as leading life form of the area encompassing 30.35% species, followed by Hemicryptophytes 20.23% and Megaphanerophytes 16.66%. The biological spectra indicating prevailing climatic conditions of the area and adaptation of vegetation to these conditions. The finding of current exploration revealed that Therophytes and Microphyll were dominant in the study area depicting heavy biotic pressure due to deforestation, over grazing and soil erosion. Keywords: Biological spectrum, Therophytes, Sathan Gali, Mansehra, Pakistan World Scientific News 87 (2017) 136-149 1. INTRODUCTION The study area, Sathan Gali can be located between 34.36132 to 34.36650 North and 073.11067 to 073.12488 East longitude in district Mansehra of Khyber Pakhtoonkhawa (KPK) Pakistan.

These compounds can also act as chemical messengers, physiological regulators or protectants against pathogens in the defense reactions of plants. Flavonoid activity is regulated by the addition of various substituents, usually mono- or oligosaccharides of common sugars, such as glucose, rhamnose or galactose. In some plants, glucuronic acid is attached, and this sugar is often acylated by phenylpropanoic acids. Identification of these compounds and their derivatives is of great importance to understanding their role in plant metabolism and defense mechanisms; this research is important because flavonoids are frequently a significant constituent of the human diet. In this study, we identify the flavonoid conjugates present in Axyris amaranthoides L. extracts and demonstrate the usefulness of high-resolution mass spectrometry (HRMS) analyzers for the differentiation of isobaric compounds and the utility of fragmentation spectra for the differentiation of isomeric structures.
