“… Zielinska, Turemko, Kwiatkowski, & Zielinski (2012) have identified the existence of orientin, vitexin, homoorientin, and isovitexin in common buckwheat seeds. In contrary, the accumulation of vitexin, isovitexin, orientin, and isoorientin has been reported in cotyledons and seeds of common buckwheat ( Matsui & Walker, 2019 ), while these flavones noted in F. cymosum ( Jing et al, 2016 ). Four flavones including orientin, isoorientin, vitexin and isovitexin have been identified from common buckwheat sprouts ( Kwon et al, 2018 ), while these flavones isolated from seeds, sprouts, and germinated seeds of common and Tartary buckwheat ( Zhu, 2016 ).…”

“…Different types of flavonoids have been detected from the root, flower, fruit, seed, sprouted seed, seedling, seed coat, Seed husk, and processed food of buckwheat ( Borovaya and Klykov, 2020 , Matsui and Walker, 2019 , Park et al, 2017 ) by using different detection methods ( Table 2 ). The content of flavonoids depends on various factors including plant growth stage, organ, cultivated buckwheat species, growing season and area ( Matsui & Walker, 2019 ). Usually, the content of flavonoids in Tartary buckwheat (~40 mg/g) is more than Common buckwheat (~10 mg/g), estimating about 100 mg/g in leaves, stems, and flowers of Tartary buckwheat.…”

“…The expression of genes responsible for anthocyanin synthesis occurs in the roots of buckwheat. Therefore, anthocyanins may be carried from the bottom of the stem or root to the apex of the stem of buckwheat ( Matsui & Walker, 2019 ). Still, more research is required to explain the process.…”

“…Flavonols in plant tissues are mostly in the form of O-glycosides. Flavones are not widely distributed and are mainly represented in the plants by C-glucosides of apigenin and luteolin [31]. The major compounds present in Passiflora species are C-glycosyl flavonoids, such as isovitexin (IV, apigenin-6-C-glucoside) and orientin (OR, luteolin-8-C-glucoside) [32].…”

Functional constituents in the leaves of Passiflora plants contain antidepressant and antianxiety effects which are beneficial to human health and fitness. The objective of this study was to investigate leaf growth, physiological parameters, and secondary metabolite contents of Tainung No. 1 variety (P. edulis × P. edulis f. flavicarpa.) and P. suberosa in response to three light intensity conditions, including 100% light intensity (LI-100), 50% light intensity (LI-50), and 15% light intensity (LI-15) for 2 months. The leaf number, length, width, area, dry weight (DW), minimal fluorescence (Fo), maximal fluorescence (Fm), maximum photochemical efficiency of photosystem II, and soil-plant analysis development (SPAD) values of all tested plants increased with a decreasing light intensity, except for the leaf number and DW of P. suberosa plants. Low values of the net photosynthetic rate, transpiration rate, and stomatal conductance of Tainung No. 1 leaves in the LI-15 treatment showed the acclimation capacity of these plants. These observations together with high values of leaf growth traits of Fo, Fm, SPAD, and the intercellular-to-atmospheric CO2 concentration ratio indicate their physiological plasticity, which is of fundamental importance when cultivating plants in environments with different light availabilities. Wide variations occurred in total phenol (TP), total flavonoid (TF), orientin (OR), and isovitexin (IV) contents of the two Passiflora varieties, and P. suberosa contained higher TP and TF contents than did Tainung No. 1 in each light treatment but IV content of P. suberosa was lower than that of Tainung No. 1 in the LI-15 treatment. Moreover, increases in TF, OR, and IV contents of Tainung No. 1 and P. suberosa were clear in the LI-50 and LI-100 treatments, respectively, compared to LI-15 treatment. Leaf growth, physiological parameters, and secondary metabolite accumulations in Passiflora species can be optimized for commercial production via lighting control technologies, and this approach may also be applicable to leafy vegetables to produce a stable industrial supply of high leaf yields and metabolite contents.

The present review focuses on the physico‐chemical properties of buckwheat (BW) and shows that its incorporation makes food more nutritious. The bioactive substances included in BW, including vitamins, proteins, flavonoids, phenolic acids, dietary fibre, and fagopyrins are effective in treating chronic illnesses. It is also a rich source of protein of excellent quality as it contains balanced amino acids. Various bioactive compounds like phenolics, flavonoids including orientin, quercetin, rutin, vitexin, isovitexin and isoorientin, tannins and steroids help in providing therapeutic benefits. It has a number of beneficial impacts on health, including anti‐inflammatory, anti‐hemorrhagic, cardiovascular, antioxidant, and blood vessel protective properties. The food sector has experienced an increased interest in producing items based on BW, which boasts advantageous flavor profiles and technical attributes while offering health benefits and accommodating those with gluten sensitivity. BW is a beneficial ingredient for bread, rice, soup, cakes, noodles, cookies, and gluten‐free beer due to its functional properties. This review also emphasizes on the BW as a functional food in numerous industries including agriculture, food, pharmaceutical and as animal fodder. It provides researchers knowledge that could be useful for developing future plans, such as selecting BW as promising bioactive ingredients for functional foods.
