“…S. oblonga is listed as a vulnerable species in International Union for Conservation of Nature (IUCN) red list of threatened species (2016), due to its overexploitation and the extensive use of its roots and stems. Apart from its antidiabetic activity, S. oblonga is also reported to have antilipidemic, antimalarial, anti-inflammatory, antimicrobial, antiperoxidative, antileukemic, and astringent properties [13][14][15][16][17][18][19].…”

Salacia oblonga is used to treat diabetes, hypocholesteremia, gonorrhea, rheumatism, asthma, inflammation, oxidative stress, etc. In the present study, the antidiabetic activity of S. oblonga methanolic root extracts collected from three geographical locations, viz., Eleshwaram (Andhra Pradesh), Thoothukudi (Tamil Nadu), and Karwar (Karnataka), was studied in vitro. Among the three extracts, S. oblonga root extracts from Eleshwaram showed maximum α-glucosidase and α-amylase inhibitory activities, indicating better antidiabetic activity. Acute toxicity studies of S. oblonga carried out in Albino Wistar rats showed no toxicity. Further, in vivo studies showed antidiabetic and antilipidemic activities in Albino Wistar rats with induced type II diabetes mellitus. Type II diabetes mellitus was induced in the experimental rats by intraperitoneal injection of nicotinamide and streptozotocin. The rats were orally fed different doses (ranging from 0 to 400 mg/kg body weight) of S. oblonga root extracts from Eleshwaram for 14 days. Blood glucose, lipid, bilirubin, and creatinine levels were analyzed on day 0, 7, and 14. The S. oblonga root extract from Eleshwaram decreased the glucose levels in a dose-dependent manner as well as the lipid, creatinine, and bilirubin levels in diabetic rats. Thus, the present study demonstrates antidiabetic and antilipidemic properties of S. oblonga root extracts.

“…Within Salacia species, S. macrosperma has the highest percentage of polymorphic of 84.27% followed by S. fruticosa (48.31%) and S. oblonga. Since some of the species of Salacia are endangered, the effort to conserve germplasm by micropropagation of S. chinensis [15], S. reticulata [16], and S. oblonga [17] has been carried out. Molecular analysis suggests that S. chinensis has the lowest variation within the species, making it a suitable candidate for large-scale micropropagation, conservation, and alternative for other endangered species of Salacia.…”

The genetic diversity of 10 genera belonging family Celastraceae (four Salacia species and nine other genera) was analyzed using 11 intersimple sequence repeat (ISSR) primers. Species discriminating ability of DNA barcodes rbcL, matK, and internal transcribed spacer (ITS) was evaluated for Salacia species sequences originating from Western Ghats of Karnataka and Kerala. For ISSR analysis, a total of 46 samples were collected from Western Ghats of Karnataka. ISSR primers revealed a mean polymorphism of 29.21 ± 7.89%. The DNA barcodes showed a high level of universality for polymerase chain reaction and sequencing. The ITS had the highest discriminate ability of 67.13% in the neighbor-joining tree-based method and in TaxonDNA software's, Best match (BM) and Best close match (BCM) had 59.59% and 58.58% correct identification success, respectively. Consortium for the Barcode of Life Plant Working Group's recommended barcodes matK, rbcL, and combined matK + rbcL, had lower correct identification success in both the tree-based method and TaxonDNA's BM and BCM.

“…J. parkeri can be propagated from seeds, but has a low germination percentage and slow seedling growth. Propagation by asexual means can be an effective alternative approach in sustaining genetic identity and populations [7]. Hence, propagation through cuttings should be considered.…”

Propagation of Jasminum parkeri: A Critically Endangered Wild Ornamental Woody Shrub from Western Himalaya

et al. 2021

Jasminum parkeri Dunn is a narrowly endemic, critically endangered woody ornamental shrub confined to sub-temperate zone of Western Himalayas, and rediscovered from its type locality after a lapse of about 100 years. In the present study, a propagation technique of J. parkeri, using stem cuttings, was established for the first time through application of auxins, namely, indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and indole-3-butyric acid (IBA), at varying concentrations ranging from 1000 to 4000 ppm. The highest rooting percentage (98.33% (85.68% ± 4.32)), number of primary roots (36), root length (29.68 cm) and survival percentage (96.67% (83.85% ± 6.16)) were recorded for cuttings treated with 3000 ppm NAA. The phenological comparison between pot plants propagated through seeds and stem cuttings in a naturally ventilated polyhouse revealed a reduction in vegetative and flowering phases in cutting raised plants. Additionally, a noteworthy adaptive behavior of two weeks of early flowering and four weeks of extended flowering (February to October) was observed in plants raised under polyhouse conditions. This method will help in protecting the species from population decline, thereby significantly increasing its potential to be harnessed as an ornamental plant in India. Furthermore, plants grown ex situ will be reintroduced in natural populations.
