Comparison of antioxidant properties and flavonoid of natural and In vitro cultivated Nardostachys jatamansi

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.

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.

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.
