“…It is intriguing to notice that the chemical compositions of the essential oils from Nardostachys jatamansi and Indian valerian have been compared in published studies. State that India, Nepal and Bhutan have banned the export of Nardostachys jatamansi (Bhattarai et al, 2002).This plant reproduces vegetative and by its seeds, which are presumably pollinated by tiny insects like flies. Nautiyal et al, (2003) review that seed germination rates between 10 and 20%.…”

Background: India has very rich diversity of medicinal plants. Medicinal plants are thought to be a rich source of ingredients that can be used in the development of pharmaceutical or synthetic drugs. Aside from that, these plants play an important role in the development of human drug all over the world. Whether in modern or traditional medicine, medicinal plants are used to maintain health, to treat a specific condition, or both. Nardostachys is one of the most important medicinal plant having several therapeutic properties. It is threatened in its natural habitat due to over exploitation for therapeutic purposes and high demand in the traditional medicine system. Keeping these points in mind, we attempted to investigate alternative uses of in vitro grown plants in place of wild plants without disrupting plant-based therapeutics and market demand. And then compare the root extract of the Nardostachys jatamansi plant’s antioxidant and flavonoid levels under in vitro and natural growth conditions. Methods: Nardostachys jatamansi is a plant that is widely used in traditional medicine systems. Because of its wide spread use in traditional medicine, this plant is considered endemic. In our study, we compare of antioxidant quality and Flavonoid amount of Natural and in vitro propagated Nardostachys jatamansi. Firstly we cultivated in vitro plants from Nardostachys jatamansi nodal explants for comparative analysis. The methanol extract of in vitro grown and wild-type plant root extract was then prepared using the maceration method. The extract was subjected to a comparative DPPH method to determine the presence of antioxidant potential in natural and in vitro grown plants. Furthermore, the HPLC analysis was used to detect and quantify the amount of Quercetin in both natural and in vitro propagated plants. Result: When grown in vitro at a higher concentration, the roots of Nardostachys jatamansi have greater antioxidant potential than when they are grown naturally. They demonstrated antioxidant DPPH radical scavenging activity, with an IC50 value of 29.55 µg/ml for in vitro generated plants and 24.18 µg/ml for naturally grown plants. The concentration of Quercetin (mg/ml) for natural plant species is 1.95 and for in vitro propagate plant is 1.83. The HPLC analysis presents distinct peaks, with the main peaks having retention time for standard Quercetin (10.38) in the natural plant (10.34) and in vitro grown plants (10.32). In the end, natural-type species that had been produced in vitro were used to obtain the potential of micro propagated plants. The DPPH test and flavonoid were tested on the root extract of natural and in vitro plants. Both plants displayed promising antioxidant activity and an HPLC study identified the Quercetin component.

“…Altogether, 23 species of Pteridophytes were documented from Gujarat state of western India and out of which Equisetum debile and Isoetes coromandelina are in the state of extinction (Rajput et al, 2016). A total of 105 species of Pteridophytes under 19 families and 45 genera were recorded from Manaslu Conservation area (Bhattarai & Rajbhandary, 2017). Likewise, 22 Pteridophytic species belonging to 12 families and 17 genera have been reported as edible of the total 394 species of wild edible plants in Nepal (Dangol, 2017).…”

The study of Pteridophytic flora of Bhimkalipatan, Pokhara was conducted from May 2018 to October 2018. The Pteridophytic plants were collected and then dried for herbarium specimen preparation. The prepared Herbarium voucher specimens were identified based on standard literatures and finally verified from KATH, Kathmandu. A total of 27 species under 19 genera belonging to 11 families were recorded. The family Polypodiaceae was the largest family with eight species under five genera. The family Pteridaceae stood second with six species under three genera. The family Dryopteridaceae was third largest family represented by three species under three genera. In the same way, the families Lygodiaceae and Thelypteridaceae were represented by two species each under two genera respectively. The remaining six families i.e. Davalliaceae, Equisetaceae, Lycopodiaceae, Nephrolepidaceae, Selaginellaceae and Woodsiaceae were represented by one species each. The largest genera were Pteris and Pyrossia representing three species each followed by Adiantum, Drynaria, Lygodium and Thelypteris with two species each respectively and the remaining 13 genera are monotypic genera. Habitat wise, the collected species were terrestrial represented by nine species followed by seven epiphytes, two climbers and one lithophyte. Likewise, three species were found as terrestrial, epiphytes and lithophytes; three species as epiphytes and lithophytes and two species as terrestrial and lithophytes.
