“…Despite coming from the same type of plant, antioxidants in cassava leaves and peel had different levels. Similar results have also been reported by Ekeledo et al [76], who found that yellow cassava peel extract had higher scavenging activity than cassava stem extract. Gonçalves et al [77] also found differences in antioxidant activity in the leaves, seeds, pulp, and peel of Chamaerops humilis L. These differences could be caused by alterations in the structure of the phenolic components in plants due to variations in cell structure and chemical substances in plant tissues.…”

Identification of antinutritional, antioxidant, and antimicrobial activity of plants that cause livestock poisoning in Bojonegoro Regency, Indonesia

et al. 2022

Background and Aim: The utilization of cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves from Bojonegoro Regency has led to the poisoning of livestock due to antinutritional factors. Nevertheless, the plants are known to have bioactive components and potential antioxidant and antibacterial activity if appropriately processed. This study aimed to determine the antinutritional compounds as well as the antioxidant and antibacterial potential of these plants responsible for livestock poisoning in the Bojonegoro Regency. Materials and Methods: Extraction was performed by the maceration method using 70% (v/v) ethanol solvent. The samples were analyzed qualitatively to determine the presence of tannins, alkaloids, oxalates, cardiac glycosides, and cyanogenic glycosides. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl method, while the antimicrobial activity was assessed by different testing concentrations (125, 250, and 500 mg/mL) against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. Results: The ethanolic extract of the plants was found to contain antinutritional tannins, alkaloids, cardiac glycosides, and cyanogenic glycosides suspected of causing livestock poisoning. Despite the presence of these antinutrients, all extracts also had antioxidant and antibacterial potential. Cassava peels and sweet potato leaves had the highest antioxidant activity, whereas Chinese Albizia leaves had the most potent antibacterial activity. Conclusion: Cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves obtained from Bojonegoro Regency and used as agricultural waste contain antinutritional factors but also possess potentially effective antioxidant and antimicrobial components.

“…The highest total phenols extracted was 0.23 mg/g at 140°C while the least was at 200 °C. These values were much lower than the 2 mg/g reported by Ekeledo et al, 2021 in white peel cassava after treatment with 80% methanol at ambient temperature. The total phenols in our untreated sample (RT) is still lower than the value reported by Ekeledo et al (2021), showing that the difference might be due to difference in the cassava variety used.…”

Cassava peels are currently underutilized with about 23 million metric tons discarded annually in Africa as by-products, causing environmental pollution. However, cassava peels have been reported to consist about 50% total polysaccharides including fibers. Subcritical water treatment also referred to as hydrothermal liquefaction, which is a green technology using only water as solvent for liquefaction of compounds was employed in this study to liquefy the cassava peel. The liquefied solid was further characterized by determining the liquefaction yield, total carbohydrate, total phenol and cyanide contents. Cassava peels liquefaction yield reached 68.4% at a treatment temperature of 140°C but decreased to 38.4% at 200°C. Cassava peels liquefied at 140°C also had the highest total phenol contents. High temperature denatures total phenolic compounds, hence the resulting maximum concentration of 0.23 mg/g was obtained at 140°C. The cyanide content decreased sharply from 5.58 µg/ml at 25°C to 2.1 µg/ml at 200°C.The total carbohydrate content was also highest at a treatment temperature of 140°C. The liquefied cassava peel showed good emulsification property. These results suggest that subcritical water treatment of cassava peel can be used for liquefaction as an environmentally friendly technology and that the liquefied solid have some potential industrial applications.

“…19 Extractions may also be influenced by the variety of the plant, particle size, and plant parts. 90 For instance, the phenolic content was 681.5 and 442.4 GAE mg/100 g in the peel and the stem from the yellow-fleshed cassava variety with a particle size of 0.2 m, respectively. 90 In their study, Gnamien et al (2022) evaluated the energy values, carbohydrate, and starch contents of cassava roots to identify the most favorable harvest and maturity stage that would yield cassava roots with the highest nutritional value.…”

Cassava ( Manihot esculenta Crantz) is considered one of the essential tuber crops, serving as a dietary staple food for various populations. This systematic review provides a comprehensive summary of the nutritional and therapeutic properties of cassava, which is an important dietary staple and traditional medicine. The review aims to evaluate and summarize the phytochemical components of cassava and their association with pharmacological activities, traditional uses, and nutritional importance in global food crises. To collect all relevant information, electronic databases; Cochrane Library, PubMed, Scopus, Web of Science, Google Scholar, and Preprint Platforms were searched for studies on cassava from inception until October 2022. A total of 1582 studies were screened, while only 34 were included in this review. The results of the review indicate that cassava has diverse pharmacological activities, including anti-bacterial, anti-cancer, anti-diabetic, anti-diarrheal, anti-inflammatory, hypocholesterolemic effects, and wound healing properties. However, more studies that aim to isolate the phytochemicals in cassava extracts and evaluate their pharmacological property are necessary to further validate their medical and nutritional values.
