“…On the other hand, the surfactant property of saponins means they can be quantified in quinoa grains with the Afrosymetric method because the formation of a stable and persistent foam at the liquid/air interface indicates the presence of saponins (Amankeldi et al, 2018;Yousif et al, 2021). The standard afrosymetric method was initially developed by Koziol (1991), in the search for a simple technique to extract and determine the presence of saponins in quinoa grains and was used to evaluate more than 5000 quinoa genotypes from Latinreco (Ecuador), with significant results.…”

Quinoa (Chenopodium quinoa Willd.) is a pseudocereal that, in addition to presenting good nutritional characteristics in the grain, has secondary metabolites in the episperm of the seeds and, within them, saponins. Saponins are characterized by being emulsifying, foaming and generating a bitter taste. This metabolite has not been completely studied in quinoa materials from Colombia. For this reason, the objective of this research was to quantify the content of saponins present in quinoa materials from the department of Boyacá using three afrosimetric methods. For this, a completely randomized design (CRD) was implemented with a factorial arrangement of 3 (afrosimetric methods) x 5 (quinoa materials). From the quantification of saponins, it was determined that the Amarilla de maranganí genotype, was the one that presented the highest content in all the evaluated methods; the standard afrosimetric method being the most efficient. Finally, the conglomerate analysis allowed to discriminate the materials in sweet quinoas such as Tunkahuan and Blanca de Jericó with saponin contents lower than 0.06%, and in bitter quinoas (Negra de la Colorada, Dorada and Amarilla de Maranganí) with contents higher than 0.11%. The biochemical characterization of the germplasm will allow a selection of genotypes suitable for consumption and for the industry, given the potential use that saponins currently have.

“…For industrial processes, foams can occur during processing of food, pharmaceutical, and personal care products [28,29]. The formation of stable foam is associated with a reduction in surface tension at the liquid-air interface [30]. Adding surfactant is a possible way to enhance foam stability, which is preferable for achieving good texture in food such as ice-cream, beer, cream, and coffee [29].…”

Detergent Plants of Northern Thailand: Potential Sources of Natural Saponins

2019

The natural forests of Northern Thailand are the mother source of many utilisable natural products because of their diverse flora and fauna. Northern Thai people have learned to utilise plants, in particular those of plants with cleansing properties, since the beginning of time. Several local species of detergent plants in Thailand are traditionally used by the locals and indigenous people. However, these plants may become extinct because their habitats have been replaced by industrial agriculture, and their uses have been replaced by chemically synthesised detergents. Researchers need to study and communicate the biology, phytochemistry, and the importance of these plants to conserve natural biodiversity of Northern Thailand. Of many utilisable detergent phytochemicals, natural saponins are known as bio-based surfactant and foaming agents. Their physiochemical and biological properties feature structural diversity, which leads to many industrial applications. In this review, we explained the term “detergent” from the physiological mechanism perspective and the detergent effects of saponins. We also compiled a list of Thai local plants with cleansing properties focusing on the saponin-containing plants. Future studies should investigate information relative to plant environment, ethnobotanical data, and the bioactive compound content of these plants. The knowledge acquired from this study will promote the maintenance of the local biodiversity and the conservation of the detergent plant species found in Thailand.

“…On the other hand, high or low saponin contents cause quinoa genotypes to be classified as sweet or bitter [12]. There are various quantification methods, including the notable afrosimetric method, where the formation of a stable and persistent foam in the liquid/air interface indicates the presence of saponins [13]. The spectrophotometric method determines the total number of saponins by measuring the absorbance of the sample at a set wavelength, and the chromatographic method identifies a specific type of saponins with a defined pattern [11].…”

Quinoa has a high nutraceutical potential because of the presence of secondary metabolites called saponins, which have industrial and medicinal uses and protect against attacks by pathogens. These compounds are found especially in the seed coat and give the grain a bitter taste; therefore, they must be eliminated before consumption. Despite the potential use in Colombia, there are few studies aimed at quantifying this metabolite. Therefore, the objective of this research was to evaluate two extraction methodologies (physical and chemical) and two methods for quantifying saponins in five quinoa genotypes grown in Colombia. The most efficient extraction method was the physical method. The saponin contents of the five genotypes were variable. The cluster analysis differentiated the genotypes into two groups: low saponin content (<4.49 mg/g seed) and high saponin content (>14.76 mg/g seeds). Blanca de Jericó had the lowest saponin content (<0.40%), and Amarilla de Maranganí had the highest content (>0.18%). Identifying more efficient methodologies for extracting and quantifying saponins will allow a better characterization of the germplasm and selection of genotypes with desirable characteristics for both consumption and industrial use.
