Fagopyrum Esculentum Moench

Buckwheat (Fagopyrum esculentum, Family Polygonaceae) is an annual pseudo-cereal crop with healing benefits. However, the genetic improvement of common buckwheat has achieved only limited success, mainly due to buckwheat’s dimorphic flowers and heteromorphic self-incompatibility. Here, we develop a useful protocol for indirect somatic embryogenesis and subsequent plant regeneration from hypocotyl explants of F. esculentum. Firstly, the initial calli of hypocotyl explants were induced on Murashige and Skoog (MS) basal medium containing 2.0 mgL−1 2,4-D and 1.5 mgL−1 6-BA for 30 days culture, and then the yellowish white friable embryogenic calli were developed when the initial calli were transferred to fresh MS basal medium supplemented with 1.0 mgL−1 6-BA and 0.5 mgL−1 thidiazuron (TDZ)two to three times subculture at 40–60 days intervals. Subsequently, the somatic embryos were able to germinate from embryogenic callus sub-cultured on MS basal medium containing 1.0 mgL−1 6-BA and 0.5 mgL−1 TDZ with 15% potato puree for 20 days subculture. Finally, maximum mean percentage (75.75%) of somatic embryo-derived plants were obtained when the mature somatic embryos were transferred to MS basal medium without growth regulators for 40 days culture. Our result provides a useful protocol for plant regeneration and SE from hypocotyl explants of F. esculentum.

Background: Fagopyrum esculentum Moench. is a herb consumed as food and has medicinal value. It is a rich source of bioactive nutrients which cure and prevent many ailments. Traditionally, it is used to treat hypertension, diabetes, constipation, cancer etc. Methods and Objective: Present work illustrates morphological, microscopic and physicochemical parameters of Fagopyrum esculentum seeds as per WHO guidelines, in vitro antioxidant activity; assessed by DPPH scavenging method, hydrogen peroxide scavenging assay and β-carotene linoleic acid bleaching method and study of lipid lowering potential of the ethyl acetate and ethanol extract of seeds on normal diet fed Wistar rats. Results: Morphological studies delineated the triangular shape, dark brown colour, 8 mm length and 6 mm width of the seed. The microscopic examination of the transverse section of seed depicted features like testa or pericarp (seed coat), the endosperm, embryo and sclerenchyma cells. Study of physiochemical parameters exhibited 0.3±0.02% of foreign matter and 1.44±0.51% crude fibre content. Total ash, acid insoluble ash and water soluble ash value were 6.7±1.7%, 1.9±0.23% and 3.9± 0.31% respectively. Alcohol soluble and water soluble extractive value came out to be 65.02± 3.21 mg/g and 12.7±1.24 mg/g respectively. Foaming index was less than 100, swelling index was found to be 0.5±0.01 ml/g. Loss on drying was 4.02±1.27%. Phytochemical screening of ethyl acetate and ethanol extract revealed the presence of alkaloids, carbohydrates, phenolic compounds, phytosterols and flavonoids. Trace amount of heavy metals (arsenic, cadmium, lead, mercury) were determined by atomic absorption spectrophotometer. Pesticide residue analysis confirmed the presence of nontoxic pesticides like dimethipin, hymexazol, phenothrin-2, methoprene, triadimenol, prohydrojasmon- 1, jasmolin ii, triademinol, jasmolin i, prohydrojasmone i, cyromazine in both the extracts by gc-ms spectrometer. The ethyl acetate and ethanol extract has shown significant in-vitro antioxidant activities demonstrated by the DPPH method (IC50 = 94.37±2.51 and 216.04±4.39 μg/ml respectively), hydrogen peroxide scavenging assay (IC50 = 83.72±3.72 and 193.47±5.05 µg/ml respectively) and β-carotene bleaching method (IC50 = 100.67±4.01 and 205.39±2.89 µg/ml respectively). Lipid lowering study performed on Wistar rats demonstrated a significant (p<0.001) decrease in serum Total Cholesterol (TC), Triglyceride (TG) and increase in High Density Lipoprotein (HDL) level as compared to normal group. Both the extracts have shown a non significant difference in the level of TG as compared to standard drug atorvastatin, depicting that the efficacy of extracts is at par with that of standard drug atorvastatin. Conclusion: Pharmacognostical study of the plant can be a very good tool for identification as well as authentication of a herb. Moreover, these parameters may be helpful in the development of monograph of the plant. Pharmacological activity confirmed Fagopyrum esculentum Moench. seed to be a good antioxidant and have lipid lowering potential.

Fagopyrum Esculentum Moench

Common buckwheat (Fagopyrum esculentum Moench) is a valuable source of proteins, B vitamins, manganese, tryptophan, phytochemicals with an antioxidant effect, and the natural flavonoid rutin. Due to its composition, buckwheat supports the human immune system, regulates blood cholesterol, and is suitable for patients with diabetes or celiac disease. The study aimed to compare the allocation of selected phenolic acids (neochlorogenic acid, chlorogenic acid, trans-caffeic acid, trans-p-coumaric acid, trans-sinapic acid, trans-ferulic acid) and flavonoids (rutin, vitexin, quercetin, kaempferol) in the leaves, flowers, and grain of buckwheat cultivars of different origin. The content of individual phenolics was determined by the HPLC-DAD method. The results confirmed the determining role of cultivar on the relative content of chlorogenic acid, trans-caffeic acid, trans-sinapic acid, vitexin, and kaempferol in buckwheat plants. A significantly negative correlation among concentrations of phenolic acids in different common buckwheat plant parts shows that there are different mechanisms of genetic influences on the concentration of phenolic substances in common buckwheat flowers, leaves, and grain. These differences should be taken into account when breeding buckwheat for a high concentration of selected phenolic substances.
