“…The same results were found by observing the TPC value of water and acetone at 71.7 and 78.4 mg GAE/g (Barthet et al, 2014). Fennel water extract also showed lower total 2017), who presented that total flavonoid contents were high in acetone and less in water, and alternate results were found by Punia and Deen (2016), who mentioned that the TFC of water extract flaxseed was 92.00 ± 2.34 mg/g and flaxseed ethanol extract was 185.00 ± 1.04 mg/g. Water extract depicted lower total flavonoid content, while ethanolic extract showed the highest flavonoid content, and the same results were found by Goswami and Chatterjee (2014).…”

The recent era has focused on screening medicinal plants/seeds for phytoconstituents, potential agents for usage as medications, and other pharmaceutical items. Tocopherols, carotenoids, ascorbates, polyphenolics, and terpenoids are naturally occurring phytoconstituents from plants that have been investigated and used as alternative therapeutic agents to treat a range of illnesses caused by oxidative stress (Süntar, 2020). Due to their numerous advantageous uses, medicinal plants are highly sought after and prevalent in the functional food and biopharmaceutical sectors (Jaddu & Katam, 2018). Herbs extensively used as medicinal material include

“…Similar to radical scavenging activities, all extracts were more effective than α-tocopherol, with the exception of the cupric reducing potential (Table 2). As shown in Figure 2, our extracts demonstrated greater efficiency in scavenging DPPH than the standard antioxidants (ascorbic acid and Trolox) as well as flaxseed from Hisar and Rajmahal hills, as reported by [25]. The authors [25] reported a DPPH scavenging activity of approximately 70% at a concentration of 0.5 mg/mL for both varieties.…”

“…These results are higher than water extract (2.1 mg QE/g) and acetone extract (5.11 mg QE/g) of flaxseeds from Lahore, Pakistan [38]. Besides, TFC in the ethanolic extracts of the local or foreign registered varieties of flaxseed we studied were found to be higher than in the ethanol extract of flaxseed (Hisar) (62.67 mg/g) and flaxseed (Rajmahal hills) (185.00 mg/g) [25].…”

Flaxseed, also known as flax or linseed (Linum usitatissimum L.), is one of the oldest crops. It is used for oil and fiber production. The species displays a broad range of biological activities due to its chemical compounds. It has a widespread geographical distribution, and a large number of its varieties have been evaluated for their biological efficacy and nutritional value. This study investigates fifteen varieties of the species, some of which are examined for the first time. In this regard, a series of chemical composition analyses and antioxidant assays were carried out. Accordingly, total phenolic content ranged between 613.6 (Michael) and 3164.6 (Atalanta) mg GAE/g, whilst total flavonoid content varied from 176.25 (BonnyDoon) to 689.20 (Mcduff) mg QE/g. Regarding the radical scavenging assays, the values obtained were significantly higher than those of the standard antioxidant (ascorbic acid). Furthermore, the extracts exhibited chelating activity for ferrous ions and a cupric reducing capacity that was comparable to that of the standard. The oil content values of the varieties ranged from 0.82 g/100 g (Michael) to 2.14 g/100 g (McGregor). The percentage of α-linolenic acid varied between 39.21% (McGregor) and 54.13% (Nareum).
