Download or read book Antioxidant Activity of Selected Wild Orchids of Nepal written by Mukesh Babu Chand and published by GRIN Verlag. This book was released on 2018-01-16 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2015 in the subject Biology - Botany, grade: -, , language: English, abstract: The inhibitory or delaying action of both the synthetic chemicals and naturally occurring phytochemicals against oxidative damage to tissues by free radicals produced in biological system of living organisms is known as antioxidant activity. Since some phytochemicals are responsible for biological as well as medicinal activities, nine wild orchids of Nepal were assessed for total polyphenolics and flavonoids content along with the antioxidant activity. The ethanolic extract of Eria graminifolia pseudobulbs, Gastrochilus acutifolius leaf and root, G. distichus whole plant, Luisia trichorhiza leaf and root, Otochilus albus pseudobulbs, Papillionanthe uniflora whole plant, Pholidota articulata leaf and pseudobulbs, Rhynchostylis retusa leaf, and Trudelia cristata leaf and stem were prepared by Soxhlet extraction. Phytochemicals were detected by previously established protocols with minor modifications. The total flavonoids were estimated with aluminium chloride method and total polyphenolics content with Folin-Ciocalteu phenol reagent method. Antioxidant activity was assessed by DPPH (2, 2-diphenyl-1-picryl hydrazyl) free radical scavenging assay. There was significant variation of total flavonoids, total polyphenolics content and antioxidant activity among the orchid extracts at P = 0.05. The total flavonoids varied with highest in Rhynchostylis retusa leaf (110.68 ± 4.52 mg QE/g) and lowest content in Gastrochilus acutifolius root (22.32 ± 1.10 mg QE/g); total polyphenolics with highest in Trudelia cristata stem (69.68±2.78 mg GAE/g) and lowest content in Gastrochilus acutifolius leaves (11.89±0.64 mg GAE/g). Also, the antioxidant activity varied with highest in Trudelia cristata stem (IC50 79.69 μg/ml) and lowest DPPH radical scavenging activity in Gastrochilus acutifolius leaf (IC50 341.79 μg/ml). However, none of the orchid extracts were as effective as quercetin – the reference compound – in radical scavenging activity (IC50 32.90 μg/ml). Total polyphenolics and flavonoids content and antioxidant activity of selected orchid extracts in this study were higher or lower than medicinal plant and orchid extracts of previous studies with considerable margin. Again, their antioxidant activity was positively associated with total flavonoids and total polyphenolics content. [...]

Download or read book Medicinal Orchids of Asia written by Eng Soon Teoh and published by Springer. This book was released on 2016-08-30 with total page 753 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book brings together a wealth of data on the botanical, ethno-medicinal and pharmacological aspects of over 500 species of Asian medicinal orchids. It starts off by explaining the role and limitations of complimentary and herbal medicines, and how traditional Asian medicine differs from Western, “scientific” medicine. The different Asian medical traditions are described, as well as their modes of preparing herbal remedies. The core of the book presents individual medicinal orchid species arranged by genera. Each species is identified by its official botanical name, synonyms, and local names. Its distribution, habitat and flowering season, uses and pharmacology are described. An overview sums up the research findings on all species within each genus. Clinical observations are discussed whenever available, and possible therapeutic applications are highlighted. The book closes with chapters on the conservation of medicinal orchids and on the role of randomized clinical trials.

Book excerpt: A beautiful, richly illustrated book on Europe's wild orchids - perhaps the most enigmatic and popular group in the botanical world. The orchid family (Orchidaceae), numbering some 25,000 species, is one of the world's two largest families of flowering plants. Whilst the vast majority of orchids are found in the wet tropics, Europe accommodates c.130 native orchid species which are equally arranged in dense inflorescences of great beauty. Furthermore, the adaptations encountered in some of the European species are just as fascinating as those of their tropical relatives. This book provides an introduction to the native orchids of Europe. It features four sections: 'Structure and systematics', 'Orchids and the environment', 'Orchid portraits' and 'How to learn more'. This part constitutes the bulk of the book, presenting individual genera in a sequence which reflects their most likely evolutionary relationships. Each genus is introduced by one page of text and illustrated by one or more colour plates on the following pages. The text gives information on how to recognise the genus, where it is distributed, and the estimated number of species it contains - alongside information on the range of environmental requirements and flowering times in the European species. Depending on the genus, additional information may be found on topics such as pollination biology, associated fungi, evolutionary relationships or systematic problems. Beautiful watercolour artwork accompanies the text, making this an indispensable gift for anyone interested in the natural world. Not only is it a useful field guide, it is also a beautiful art book.

Available in PDF, EPUB and Kindle. Book excerpt: Orchids are beautiful, aren’t they? Decorations made of these spectacular plants make the whole atmosphere divine! Their range of colour, the pattern of the flowers and the dots and ridges on the floral parts make them unique and ‘different’. Interestingly, they are the most well-praised medicinal plants in the world. For ages, most countries have been harbouring and using these plants to treat several ailments like that in Ayurved, ancient Chinese medicine, etc. They’re also advocated and boasted for potential healers. Besides, numerous folklore uses, which may or may not be documented, can be traced. Being very juvenile, our research has provided scanty (as compared to their actual uses) information on the validation part of these plants. Orchids in Traditional Medicine tries to take you to the mysteriously beautiful world of orchids, providing a glimpse into understanding their potential and medicinal uses. It also seeks to putatively understand the Ayurvedic doctrine and the existing disputes regarding the use of orchids. Let us now explore the world of medicinal orchids!

This book was released on 2022-05-03 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: A presentation of over 700 popular orchid species in 104 genera carefully detailed with beautiful photographs and concise descriptions of plants, their distribution and habitats by a well-known author and photographer. Each genus is assigned a separate chapter. Coverage of the most commonly cultivated Asian species including their varieties and cultivars (e.g. in Bulbophyllum 72 species; Coelogyne 33 species; Dendrobium 161 species; Paphiopedilum 58 species; Phalaenopsis 60 species; Vanda 44 species) is exhaustive. The orchids are photographed from their best perspective, individual blooms and entire inflorescence: additionally, many species are also shown growing in their natural habitat. Representative hybrids are included to illustrate how some species have contributed to show-worthiness of various genera, their adaptation to a wider climate range, and easy cultivation. This book is a pleasure to view; simultaneously, an easy reference for the identification of orchid species and it provides a guide on how best to grow them. Nowhere else will one find so many popular species beautifully illustrated in a single volume. A must for everyone fascinated by orchids or with a love for nature.
