“…From fraction 3, a crude mangiferin crystal is obtained, which is then recrystallized from the mixture: petroleum ether-acetone, in a ratio of 20 : 1, and purified by rechromatography on sepharose CL6B (Sigma -Aldrich) on a BioLogic low-pressure chromatograph (BioRad), which allows the pure substance of mangiferin to be isolated. 4. The total residue of fractions 1-9, except for fraction 3, is placed on a column with polyamide (Sigma) (BioLogic low-pressure chromatograph (BioRad)), where two fractions are isolated: 5hydroxy-4-methoxy-8-prenyl-2-hydroxyisopropyl dihydrofurano- [4,5:6,7]-isoflavone and a fraction consisting of quercetin and quercetin-rhamnopyranoside.…”

Hedysarum neglectum is a forage plant. Xanthone glycoside - mangiferin is extracted from this plant and used for medicine "Alpizarin". In addition to substances of xanthone nature (mangiferin and isomangiferin) Hedysarum neglectum contains sugars, vitamins and provitamins, tannins; in the underground part it contains oligomeric catechins, isoflavonoids, butylphenols, alkaloids, tannins, flavonoids, saponins, coumarins, carbohydrates, vitamin C. For selecting optimal schemes of fractionization of substances, it is necessary to resort to multi-stage schemes of group-wide (preliminary) isolation and preparative accumulation. In particular cases, it is necessary to take into account the presence of concomitant substances, as well as the effectiveness and selectivity of the sorption-chromatographic technologies used. According to the results of the studies, the use of silica gel and sefadex LH-20 for the isolation of a complex of flavonoids and gallic acid is the most effective method for the selection of the optimal variant of the preparative isolation of the total amount of BAS in mcg/ml. The results of the research allowed us to identify the target biologically active substances with a degree of extraction of at least 80%: - fractions of xanthones, flavonoids, gallic acid.

Despite the fact that in the modern world more than a thousand edible plants are used for food, only 3 staple cereal crops are grown worldwide: wheat, rice, and maize. Growing a limited number of crops often causes many problems: ranging from the loss of biodiversity, due to the constant cultivation of the same monocultures in the same areas, to the deterioration of soil quality. A way out of this situation is the selection of new untraditional and neglected plants that could grow in a wide range of temperatures, produce high yields and at the same time have a balanced amino acid composition. Pseudocereals of the genus Amaranthus L. meet these criteria. Amaranth grain and plant raw materials are used in many industries: food, medicine, cosmetics. Modern technologies do not stand still. Along with traditional methods of plant breeding, the rapid pace of development involves genetic engineering of plants, which allows the process of creating improved plants to be speeded up several times. The purpose of this study is to analyze and systematize the achievements in the field of regeneration and genetic transformation of representatives of the Amaranthus genus. The results can be used for a practical application: the genetic transformation of species of the genus Amaranthus and other close genera of plants.

Nowadays, the human population is more concerned about their diet and very specific in choosing their food sources to ensure a healthy lifestyle and avoid diseases. So people are shifting to more smart nutritious food choices other than regular cereals and staple foods they have been eating for a long time. Pseudocereals, especially, amaranth and quinoa, are important alternatives to traditional cereals due to comparatively higher nutrition, essential minerals, amino acids, and zero gluten. Both Amaranchaceae crops are low-input demanding and hardy plants tolerant to stress, drought, and salinity conditions. Thus, these crops may benefit developing countries that follow subsistence agriculture and have limited farming resources. However, these are underutilized orphan crops, and the efforts to improve them by reducing their saponin content remain ignored for a long time. Furthermore, these crops have very rich variability, but the progress of their genetic gain for getting high-yielding genotypes is slow. Realizing problems in traditional cereals and opting for crop diversification to tackle climate change, research should be focused on the genetic improvement for low saponin, nutritionally rich, tolerant to biotic and abiotic stresses, location-specific photoperiod, and high yielding varietal development of amaranth and quinoa to expand their commercial cultivation. The latest technologies that can accelerate the breeding to improve yield and quality in these crops are much behind and slower than the already established major crops of the world. We could learn from past mistakes and utilize the latest trends such as CRISPR/Cas, TILLING, and RNA interference (RNAi) technology to improve these pseudocereals genetically. Hence, the study reviewed important nutrition quality traits, morphological descriptors, their breeding behavior, available genetic resources, and breeding approaches for these crops to shed light on future breeding strategies to develop superior genotypes.
