Population Status, Distribution, Antioxidant Properties and Antibacterial Activity of Threatened Herb Gentiana kurroo Royle

Abstract

Sustainable utilization and conservation of the threatened species is a major challenge for conservationists. For the conservation and reintroduction of species, comprehensive information on the ecological elements, potential habitats and pharmaceutical importance of the species is essentially required. This has necessitated initiating studies on habitat and population ecology of the threatened species. In view of the above, the present study investigated populations of Gentian kurroo representing different habitats and aspects in Himachal Pradesh. Among the populations, mean density of G. kurroo 80.75 Ind per 100m 2 and range varied from 63.0-110.0 Ind 100m-2. The density showed direct relation with soil, slope, aspect and habitat. The particular geographical distribution of the species was sub tropical indicated species habitat specificity. Biological features, aspects, slope and pressure contributed to the critical population status of the G.. kurroo. The present investigation clearly showed that G.. kurroo populations occurred in fragmented pattern in the subtropical ecosystem. Species re-introduction should therefore carefully select suitable habitat with suggested setting in this study. The present study confirmed that population ecology, habitat distribution modelling provide assistance in the species recovery plan. The study would not only help in ecorestoration of the species and habitats but also in recovering the species population and improving its conservation.

Antioxidant and Immune Stimulating Effects of Allium hookeri Extracts in the RAW 264.7 Cells and Immune-Depressed C57BL/6 Mice

“…Many studies have reported that antioxidant effects of vegetables, plants, and herbs evaluated by ABTS radical scavenging activity. Some studies [ 31 , 32 ] showed similar results to our study outcomes of roots extract having higher activity than the leaves extract. The ABTS radical is soluble in aqueous and organic solvents [ 33 ].…”

Study on phytochemical, antibacterial and antioxidant properties of Genitiana kurroo Royle

“…With an IC50 value of 66.03 g mL -1 of water extracts, leaves had the greatest radical scavenging efficacy. While among the root extract, methanolic had the greatest level with an IC50 value of 56.56 g mL -1 for its radical scavenging effect (Lal et al, 2019).…”

“…The lower elevations of the Mandi, Sirmour, Solan, and Shimla districts of Himachal Pradesh in the North-Western biogeography provinces of the Indian Himalaya were discovered to contain potential habitats with high suitability thresholds. In primary field investigations, potential habitats were typically discovered in Himachal Pradesh oak and pine woods as well as dry grasslands (Lal et al, 2019). This species of plant is found in a few isolated pockets in District Sirmour, Himachal Pradesh at an altitudinal range of 1552 m above sea level, and the sample for the present study is taken from the village situated in District Sirmour.…”
