Abstract
BackgroundIn the present era, the attention of nutritionist diverted towards the bioactive entities present in natural sources owing to the presence of health boosting perspectives against lifestyle related disarrays.MethodsIn this context, different parts of ginger crop i.e. rhizome, leaves and flower of variety Suravi (ID no. 008) were used for the preparation of ginger extracts with 50% methanol, 50% ethanol and water via rotatory shaker for 45 min. After that, different phytochemical analysis and in vitro analyses were carried out to determine the antioxidant potential of these extracts. Lastly, the best selected extracts from each part was quantified through HPLC.ResultsThe results of current investigated indicated that ethanol extract proved to have maximum quantity of phytoceutics as compared to methanol and water. The maximum TPC, flavonoids, flavonols, DPPH assay, antioxidant activity, FRAP assay, ABTS assay and metal chelating potential was observed in ginger leaves as 780.56 ± 32.78 GAE/100 g, 253.56 ± 10.65 mg/100 g, 49.54 ± 1.74 mg/100 g, 75.54 ± 3.17%, 77.88 ± 3.27%, 105.72 ± 4.44 μmole TE/g, 118.43 ± 4.97 μmole TE/g and 35.16 ± 1.48%, respectively followed by ginger flowers and ginger rhizome. The lowest antioxidant activity was estimated in ginger rhizome. On the basis of phytochemical profiling and in vitro analyses, ethanol extracts of ginger flowers, leaves and rhizome were selected for the quantification through HPLC.ConclusionThe findings proved that maximum 6-gingerol was present in ginger leaves (4.9 mg/g) tackled by ginger flowers (2.87 mg/g) and ginger rhizome (1.03 mg/g).

Phytochemical screening test Total phenolic contents Phenolics over and above to the antioxidant perspectives owing to the valuable health boosting ability have been recognized as an essential ingredient in daily diet
It is depicted from mean values that total phenolic compounds have significantly affected by solvent and plant part the effect was observed as non-significant for part and solvent interaction
Summary
The attention of nutritionist diverted towards the bioactive entities present in natural sources owing to the presence of health boosting perspectives against lifestyle related disarrays. The food material that is mostly utilized as the source of nutraceutics are fruits, vegetables along with a number of spices that are used on daily basis in normal lifestyle These food commodities enclosed extraordinary number of bioactive moieties that can be illustrated by volatile and non-volatile assay. A number of extraction (2020) 6:12 techniques have been used to extract and quantify the bioactive entities of ginger rhizome, flowers and leaves classified as phenolic compounds. In the phytochemistry of plants, phenolic moieties have been recommended as the most important bioactive compound that are liable to be used as health boosting ingredients and can be recommended as antioxidants These phytochemicals are highly reactive in nature and can oxidize the free radical molecule such as superoxides owing to the scavenging property and can limit the process of lipid peroxidation [4]
