“…The family is widespread over the five continents, with a distribution range that extends from the Arctic Circle to sub-Antarctic islands [3]. Apart for being ornamental plants primarily grown for the beauty of their flowers, orchids have also been addressed as medicinal for centuries in Asia, Africa, Europe, the Americas and Oceania, with about 600 species and approximately 20% of the Chinese native orchids that have been and are being used for therapeutical properties [4]. More than 360 Orchidaceae, including several Dendrobium species, are listed in the earliest known Chinese and Indian Materia Medica [5].…”

The volatile fractions from fresh inflorescences and leaves of Dendrobium moschatum (Buchanan-Hamilton) Swartz (Orchidaceae) were isolated by steam distillation with a yield of 0.498% and 0.041% (weight/fresh weight basis), respectively. From GC/FID and GC/MS analyses, coumarin was identified to be the most abundant constituent and quantified as 48.8% and 47.8% of the total volatiles from inflorescences and leaves, respectively. Hydrocarbons, ketones, esters, acids and aldehydes were also detected. Long chain mono unsaturated hydrocarbons were quantified in higher amount in leaves and their structures were elucidated by GC/MS of their dimethyl disulfide derivatives. These compounds together with long chain ethyl esters and methyl ketones may represent a particular feature of this plant species and can play a critical role in the interaction with pollinator insect.

Orchidaceae is one of the two largest families in angiosperms. Orchids are popular owing to the most beautiful flowers they produce and due to their wide spread ethnobotanical importance. In this review, ethnobotanical uses and pharmacological activities of A. praemorsa is discussed by referring flora, journals, and search engines such as Google scholar, ScienceDirect and Pubmed. Ethnobotanical investigations have revealed the potential therapeutic roles of different parts of A. praemorsa. The orchid is used traditionally by for treating ailments such as stomachache, earache, backache, wounds, neuralgia, rheumatism, eye diseases, sciatica, cough and fracture. A. praemorsa is investigated for various pharmacological activities. Studies have revealed the potential of A. praemorsa to exhibit a range of bioactivities such as anticancer, antibacterial, antifungal, antioxidant and anti-inflammatory activities. In conclusion, A. praemorsa is an extensively used epiphytic orchid for medicinal purposes in several parts of the India and other countries. Major emphasis has to be given in order to conserve this medicinally important orchid species. A. praemorsa can be a promising candidate in terms of its pharmacological potential.

“…It is used as tonic and in general debility. [11][12][13][14][15][16][17][18] It has been found that in spite of its ethnomedicinal value, little work has been done on this plant. In the current investigation carried out, pharmacognostic evaluation and screening of different extracts of C. acuminatum pseudobulbs have been used against various types of bacteria in order to screen new sources of antimicrobial agents.…”

Background:Crepidium acuminatum (D. Don) Szlach (family Orchidaceae) is an ethnomedicinal plant. It is used in breathing disorders, burning sensation, Cough, decrease in bone tissue, blood disorders, tuberculosis, as refrigerant, aphrodisiac, in insect bites, rheumatism, as tonic and in general debility. It is vital component of Ayurvedic formulation "Astavarga" with trade name "Jeevak means vitality of life. Despite the common utilization of this plant, no conclusive study has been reported so far regarding the pharmacognostic evaluation and antimicrobial activity. Aim: The present study was carried to evaluate pharmacognostic evaluation and the potential of C. acuminatum as antimicrobial. Materials and Methods: Organoleptic, histochemical, microscopic, physicochemical, extractive yield were studied to standardise pharmacognostic characters and well diffusion method were carried out for antimicrobial activity. Five extracts viz. Hexane, Chloroform, Ethanol, Ethyl acetate and aqueous were evaluated against 4 bacterial strains viz. E. coli (MTCC 40), S. aureus (MTCC 87), P. aeruginosa (MTCC 424), B. subtilis (MTCC 121). Results: The diagnostic characters were evaluated and documented. All the extracts showed good antimicrobial activity. Conclusion: Obtained standards will provide referential information for correct identification, purity, standardization and preparation of monograph. The work confirms that the studied plant has potent antimicrobial activity and has potential for antimicrobial drug. These results may constitute a basis for promising future applied research that could investigate the use of this plant as antimicrobial drug.
