The present study designed to establish the diosgenin profile from eleven different Indian varieties of fenugreek, and subsequently develop powder from the best stage and variety to prepare diosgenin fortified bread. The seeds, sprouts and leaves of different fenugreek varieties were analyzed for the diosgenin using HPLC. The content of phenolics and flavonoids also estimated and assessed for its antioxidant capacity using phosphomolybdate, DPPH and FRAP. Among eleven varieties screened for diosgenin and the other compounds, tender leaf of Kasuri methi (KS) variety showed the highest content of diosgenin (466.89 ± 0.32 mg/100 g FW), phenolics (58.54 ± 2.70 mg/100 g FW) and flavonoids (1104.16 ± 43.70 mg/100 g FW) followed by Pusa Early Bunching (PEB) (444.18 ± 0.36 mg/100 g FW) and Early Bunching (EB) (409.45 ± 0.42 mg/100 g FW). Among three stages, seeds found to be a better total antioxidant, DPPH scavenging, and reducing ability. Further, based on the results, bread fortified with 1.5% KS leaf powder is found to be optimal which also has significant diosgenin content (268.91 mg/100 g DW). And the effect of KS leaf powder on amylograph and farinograph characteristics of wheat flour and quality characteristics of bread showed promising results of acceptance., Competing Interests: Conflict of interestAll the authors declare that there is no conflict of interest., (© The Author(s) 2021.)

Background: The present investigation evaluates the hepatoprotective and in vitro antioxidant effect of methanolic extract and its isolated constituent, dehydroabietylamine, in Carthamus tinctorious L, var Annigeri-2-, an oil yielding crop., Materials and Methods: The hepatoprotective effects were estimated for the parameters viz, total bilirubin, total protein, serum alanine amino transaminase (ALT) and serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) and along with the pathological findings of hepatotoxicity. The in vitro antioxidant activity was evaluated by using free radical scavenging assays: DPPH, nitric oxide radical scavenging, hydroxyl radical, reducing power, ferrous ion chelating ability and total antioxidant capacity., Results: Both the methanolic extract (at 150 and 300 mg/kg bw) and dehydroabietylamine (at 50 mg/kg bw) showed significant liver protection against CCl(4) -induced liver damage that was comparable with the standard drug, silymarin (100 mg/kg bw), in reducing the elevated serum enzyme markers. The liver sections of the animals treated with dehydroabietylamine elicit a significant liver protection compared with the methanolic extract against CCl(4) -induced liver damage. Further, both the methanolic extract and dehydroabietylamine exhibited a considerable and dose-dependent scavenging activity of DPPH, nitric oxide and hydroxyl radical. Similarly, in the reducing power assay, the results were very persuasive. In addition, the Fe(2+) chelating activity and the total antioxidant assay established the antioxidant property of the methanolic extract and its isolated constituent. Among the two experimental samples, dehydroabietylamine proved to be more effective for the said parameters., Conclusion: The potent antioxidant and its correlative hepatoprotective activity of the methanolic extract and isolated constituent dehydroabietylamine is therefore attributed to its antioxidant and free radical scavenging activities.
