Book Description
Did you know that Vanilla was formerly served as aphrodisiac by Cassanova and Madam Pompadour, and Elizabeth I loved its flavor? This is the first book that provides a complete worldwide coverage of orchids being employed as aphrodisiacs, medicine or charms and food. Opening with an in-depth historical account of orchids (orchis Greek testicle), the author describes how the Theory of Signatures influenced ancient herbalists to regard terrestrial orchid tubers as aphrodisiacs. Doctors and apothecaries promoted it during the Renaissance. Usage of orchids in Traditional Chinese Medicine, Indian Ayurvedic Medicine; by Tibetan yogins and Amchi healers for longevity pills, tonics and aphrodisiacs; by Africans to prepare 'health promoting' chikanda or as survival food when lost in the Australian bush are some highlights of the book. Early settlers in America and the East Indies often relied on native remedies and employment of orchids for such needs is described. Also covered are the search for medicinal compounds by scientists, attempts to prove the orchid's efficacy by experiment and the worry of conservationists.

Book Description
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 Description
Orchids account for a large share of global floriculture trade both as cut flowers and as potted plants, and are estimated to comprise around 10% of international fresh cut flower trade. The average value of fresh cut orchids and buds trade during 2007-2012 was US$ 483 million. In 2012, there are more than 40 countries exporting orchids and 60 countries importing orchids around the world, with the total size of the global trade equaling US$ 504 million. In India, about 1350 species belonging to 186 genera represent approximately 5.98% of the world orchid flora and 6.83% of the flowering plants in India. The publication on “Commercial Orchids” is presented in 15 interesting chapters vividly highlighting the global orchid industry, bio-diversity, conservation and bio-piracy of genetic resources, morphological and molecular characterization of valuable species, breeding approaches for improved genotypes, production of quality planting materials, physiology of tropical and temperate orchids, climate change and its impact on orchid productivity, production technology of commercial epiphytic orchids for cut flower, production technology of commercial terrestrial orchids for cut flower, orchids for pot culture, hanging baskets and tree mounting, medicinal and aromatic orchids, post-harvest management of cut flowers of commercial orchids, value addition and marketing.

Book Description
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. [...]
