Coelogyne Cristata and Pholidota Articulata Used for Healing Fractures Indian Journal of Experimental Biology Vol. 55, September 2017, pp. 622-627 Pharmacognostical evaluation of Indian folk-traditional plants Coelogyne cristata and Pholidota articulata used for healing fractures Chetan Sharma1, Saba Irshad2, Sayyada Khatoon2 & KR Arya1* 1Botany Division, CSIR-Central Drug Research Institute, Lucknow-226 031, India. 2Pharmacognosy & Ethnopharmacology Division, CSIR-National Botanical Research Institute, Lucknow-226 001, India. Received 07 May 2015; 14 September 2016 Coelogyne cristata Lindley (CC) and Pholidota articulata Lindley (PA) (Fam. Orchidaceae), locally known as ‘hadjojen’(bone jointer) are the most effective traditional remedies for healing fractures in Uttarakhand Himalaya, India. Recent pharmacological investigations of crude extracts and isolated compounds from these plant species revealed rapid fracture healing properties and osteogenic potential. This paper provides macro and microscopic characteristic features, physicochemical properties and HPTLC profiles of both the species. Microscopic studies of leaf, pseudobulb and powdered materials showed collateral vascular bundles containing large number of mucilage cells, parenchymatous cells with pitted banded lignified or beaded with mesh-like network, septate and aseptate fibres, rhomboidal crystals of calcium oxalate and pitted parenchyma. Comparative HPTLC profile showed blue and pink florescent band at different Rf values with the distinct characteristic bands at Rf 0.31, 0.47 and 0.62 corresponding to the analytical marker compounds: ursolic acid, -sitosterol and lupeol respectively in both CC and PA. Findings of this study can be used a standardized pharmacognostical markers of CC and PA for identification and authentication of their genuine herbal drug formulations as quality control markers.

  • Coelogyne Flaccida
    Coelogyne flaccida Sectie : Epidendroideae, Ondersectie : Coelogyninae Naamverklaring : De geslachtsnaam Coelogyne is afgeleid van het Griekse koilos=holte en gyne(guné)=vrouw. De stempel, het vrouwelijk orgaan van de plant, heeft aan de voorzijde een diepe holte. Flaccida betekent slap, wegens de hangende bloeiwijze. Variëteiten : var.crenulata Pfitz. :de overgang naar het voorste gedeelte van de middenlob is fijn getand. var.elegans Pfitz.: terugbuiging van de lip is onduidelijk waardoor de middenlob nauwelijks te onderscheiden is; bloemen groter en bijna reukloos. Distributie : Himalya: Nepal, Sikkim en Assam tot Burma. Komt voor op een hoogte van 1000 tot 2000 m , meestal epifytisch, zelden lithofytisch. In dichte bomenbestanden op bemoste takken. Beschrijving : Coelogyne flaccida groeit in dichte pollen in humusresten in de oksels van boomtakken. Bulben dicht op elkaar, verbonden door korte rhizomen, 10 x 2,5 cm groot en al in het eerste jaar duidelijk in de lengte gegroefd. Rijpe bulben hebben aan de basis 2 droge schutbladen en dragen 2 leerachtige bladeren, tot 20 x 4 cm, smal elliptisch, spits toelopend. De bloeistengel ontwikkelt zich uit een bijzondere uitloper in de oksel van een schutblad en staat dan op een heel klein onderontwikkelde bulbe, geheel door groene schutbladeren omgeven. De bloeistengel gaat hangen, wordt tot 25 cm lang en draagt 6 - 10 bloemen. Bloemen stervormig, 4 -5 cm in doorsnee, onaangenaam geurend. Sepalen vlak, smal elliptisch, spits toelopend; petalen teruggebogen, vrijwel even lang, maar half zo breed. Kleur wit tot licht crèmekleurig. Lip in drieën gedeeld, de zijlobben staan rechtop en omvatten half het zuiltje. De middenlob steekt naar voren, met teruggeslagen of gebogen punt.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

Among them, 9 species are in India. Commonly distributed from submontane to montane Himalaya. The genus pholidota are epiphytic herbs generally grown on rocks and trees [1]. Most plants of the genus Pholidota found in India grow as epiphytes. Some are also found growing on moist, moss covered rock structures on large, hilly slopes. On the earth, out of 4,22,127 plant species, about 35,000 to 70,000 species are used as medicinal plants [2].

  • Coelogyne Unchained Melody by Bruce Adams
    The Orchid of the Month for March: Coelogyne Unchained Melody By Bruce Adams Figure 1: Coelogyne Unchained Melody. To the left you will notice a Leptotes pohlitinocoi, a nice little miniature in full bloom with six flowers. (After a few months’ hiatus, we are back with the orchid of the month. Now that spring is underway, I have, for a change, more orchids in bloom than I have time to write about, rather than the other way around.) I will admit that I don’t particularly like white flowers. When I go to orchid shows, I gloss over the big white Phalaenopsis that seem to be requisite at the top of every orchid display. Frankly, I find it rather boring and a waste of good display space! I grow orchids for their unusual color combinations and fantastic shapes, such as found in the pleurothallids and bulbophylums, and I find Catasetum and Stanhopea species to possess amazing flowers with true wow factor. But the reality is that I really cannot grow bulbo’s or catasetums too well, pleuro’s require a lot of attention in our climate, and I just don’t have room for stanhopeas. So this month, I turn my attention to a plant that I ordinarily would not have given a second look: Coelogyne Unchained Melody, a plant which I must have received as a raffle winning, or perhaps from a “fire” sale, at a plant show. Coelogyne Unchained Melody is a primary cross between Coelogyne cristata and Coelogyne flaccida. It blooms in the spring, with hanging spikes of five to ten white flowers with a slightly yellow to orange lip.

The estimated number of orchid species varies from 12,000 to O 35,000, contributing up to 10% of all flowering plant species in the world (Dressler, 1981). Orchids form 9% of our flora, and about 1331 species are reported from India (Mishra, 2007). Orchids are extremely popular for their mesmerizing marvelous flowers in the whole world, but it is in the lesser know that many species are used in traditional systems of medicine and form remedial measures for a number of ailments.
