“…Chemical analyses realized on V. dilloniana stems showed antimicrobial and antiproliferative activities [74]. In India, local people use the stem of V. walkeriae as fodder for cows having new calves to increase their milking capacity [76] and to treat fever in cattle [77]. V. decaryana is used in the south of Madagascar for its aphrodisiac proprieties (Figure 3C) [10].…”

The Leafless Vanilla Species-Complex from the South-West Indian Ocean Region: A Taxonomic Puzzle and a Model for Orchid Evolution and Conservation Research

The pantropical genus Vanilla is a member of the Orchidaceae family, one of the largest and most diverse families of angiosperms in the world. It originated in America and differentiated in America, Africa, and Asia. About 132 species of Vanilla have now been accepted since the discovery of the genus. Within the Vanilla genus, leaflessness has appeared at least three independent times, in Africa, Asia, and America as an adaptation to drought conditions. The South-West Indian Ocean (SWIO) region, a biodiversity hotspot for orchids, is home to seven leafless species. Chloroplast markers failed to differentiate species within this recent SWIO clade. Morphological traits used for description are very similar between species and do not provide reliable identification. Moreover, some of the species have overlapping flowering periods and geographic distribution in Madagascar, increasing the probability of finding some sympatric species and, therefore, hybrids. Leafless Vanilla species from the SWIO islands are thus an excellent model for understanding the evolution of orchids. For their conservation, and to confirm the identity of these leafless species, an integrated approach with classical taxonomy using a large number of samples, intense fieldwork on biology and ecology, and molecular studies using variable markers is necessary.

“…The community inhabits different districts of Tamil Nadu, with a major part in the Southern Western Ghats, of Coimbatore and Nilgiris, followed by Erode, Krishnagiri, Vellore, Kancheepuram, Chennai, Ariyalur and Tanjavur. In Coimbatore, the major are distributed in Anaikatty, Mankkarai, Boluvampatty, Siruvani, Maruthamalai, Palamalai, Karamadai, Nelithurai, and Anaimalais (Ramachandran, Manian, 1989;Palanisamy, 1993;Balasubramanian, Prasad, 1996;Padmavathi, Ramdass, 2014).

Irulas are one of the dominant tribal communities in Southern India. The ethnobotanical knowledge used for medicinal purposes and daily food utilised by the indigenous community from Tamil Nadu, India was reviewed and presented. All the available literature, articles, reports, books and websites were reviewed for the present work. A total of 60 published records were found on ethnobotany and medicinal plants of Irulas starting from 1980 to 2023 from Tamil Nadu which was reviewed and analysed here. In this review, about 34 publications were represented from the Coimbatore district as a major contribution and 11 from Nilgiris district. A total of 663 species and 462 genera belonging to 121 families were used by the Irulas community from Tamil Nadu state. Overall, 15 major broad-type disorders were categorised for the utilisation of plant species under different ailments and diseases. About 417 species were consumed for general health purposes and disorders of fever, cold, cough, headache, migraine, cuts, wounds, and body pain, followed by 288 species for gastrointestinal and 177 species for dermatological disorders. The present review on ethnomedicinal plants provides updated valuable information and amend on the traditional folk medicine and daily food utilised by the indigenous tribe of Tamil Nadu. The ethnobotanical data could play a major role in the medicinal plant of RET species conservation. Also, this will serve as a great potential value for the locals and urban environment.

ABSTRACT:Cymbidium aloifolium is a potent medicinal epiphytic orchid plant in the Indian systems of medicine. Traditionally this plant was used in the treatment of Anti-inflammatory, Paralysis, joining fractured bones, fever, weakness of eyes, chronic illness, burns, sores etc. In the present study three different solvent (Hexane, Chloroform, Methanol) extracts of Cymbidium aloifolium plant was studied for Antibacterial activity by Agar Well Diffusion method against ten clinical pathogenic bacteria. It was observed that Chloroform extract showed significant activity than the Methanol and hexane extracts. Preliminary phytochemical screening of this plant revealed that the presences of Simple sugars, Alkaloids, Tannins, Flavonoids, Anthraquinones, Terpenoids etc. The presence of bioactive constituents is associated with the antimicrobial activity. Antibacterial activity of various solvent extracts of this plant was carried in attempt to support the use by medicinal practitioner for the treatment of various diseases. Medicinal importance of this orchid will target to meet the therapeutic demands.
