“…The most well-known health benefit of purple sweet potato is its anti-diabetic effects due to xenobiotic phytochemical constituents ( Strugała et al, 2019 ). Some of the plant’s genotypes are associated with nutraceutical value ( Escobar-Puentes et al, 2022 ). Despite its known functional value, the plant is underutilized, possibly due to safety concerns regarding the consumption of the natural plant and the lack of scientific data on its therapeutic use.…”

This study assessed the toxicity of lutein-rich purple sweet potato leaf (PSPL) extract in male Sprague–Dawley rats.Methods and study design: A total of 54 adult male Sprague–Dawley rats were used. For the acute toxicity study, three rats in the acute control group were fed 2,000 mg/kg of PSPL for 14 days. The subacute toxicity study included six rats each in four groups administered 50, 250, 500, or 1,000 mg/kg for 28 days and observed for further 14 days without treatment in the subacute control and subacute satellite groups. Changes in body weight; blood biochemistry; hematological parameters; relative organ weight; and histological sections of the heart, kidney, liver, pancreas, aorta, and retina were observed for signs of toxicity.Results: The gradual increase in weekly body weight, normal level full blood count, normal liver and kidney profile, relative organ weight, and histological sections of all stained organ tissue in the treated group compared with the acute, subacute, and satellite control groups demonstrated the absence of signs of toxicity.Conclusion: Lutein-rich PSPL extract shows no signs of toxicity up to 2,000 mg/kg/day.

“…Therefore, the Vietnamese government decided to replace rice with upland crops (sweet potato, yam, cassava, etc .). Sweet potato ( Ipomoea batatas L.) is an important food widely cultivated in tropical countries ( Escobar-Puentes et al, 2022 ). It is a rich source of vitamin A, vitamin C, manganese, copper, digestive fiber, vitamin B6, potassium (K), and iron (Fe) ( Neela & Fanta, 2019 ).…”

The available phosphorus (P) in acid sulfate soils (ASSs) is low because of fixation by aluminum (Al) and iron (Fe), resulting in decreased P use efficiency and crop yield. At present, the use of dicarboxylic acid polymer (DCAP) coated on P fertilizer is expected to improve P use efficiency and plant productivity. However, the influence of DCAP on P solubility and on the yield of sweet potato cultivated in acidic soils has not been elucidated. Thus, the aimed of this study was to evaluate the effect of the use of DCAP-coated P fertilizer on the availability and nutrient uptake of P as well as the yield of sweet potato. Under the greenhouse condition, the use of DCAP significantly improved P availability (~3 mg P kg−1), increasing tuber diameter and length by ~0.5 and ~1.0 cm, respectively. Thus, the productivity of sweet potato in the treatment 40-kg P2O5 and 60-kg P2O5 ha−1 coated with DCAP was higher by about 100 g pot−1 than that in the same rate of P fertilizers (40- and 60-kg P2O5 ha−1) not coated with DCAP. In the field experiment, P accumulation (82.7 kg P2O5 ha−1) and tuber yield (22.0 t ha−1) in the treatment of DCAP-coated with 60-kg P2O5 ha−1 were not significantly different compared with that in the treatment of 80-kg P2O5 ha−1 (82.1 kg P2O5 and 21.7 t ha−1, respectively). Furthermore, the use of DCAP combined with 75% P fertilizer increased the P availability by the same amount as that with the use of 100% P fertilizer. Hence, the use of DCAP reduced about 25% of the chemical P fertilizer applied in soil.

The effects of pullulanase debranching combined with autoclaving (PDA) at various debranching times (0 h, 5 h, 10 h, 15 h, 20 h, and 25 h) and 121 °C/20 min of autoclave treatment on the structural and physicochemical characteristics of purple sweet potato (Jinshu No.17) starch were investigated. The results indicated that the native starch (NS) was polygonal, round, and bell-shaped with smooth surfaces. After debranching treatment, the surface of the starch samples became rough and irregular. The molecular weight became smaller after treatments. X-ray diffraction C-type pattern was transformed into a B-type structure in treated samples with increased relative crystallinity. 13C NMR indicated an increased propensity for double helix formation and new shift at C1, 3, 5 region compared to NS. The apparent amylose content was 21.53% in the NS. As the swelling power decreased, the percentage of soluble solids increased and different thermal properties were observed. A higher yield of the resistant starch (RS) was observed in all treated starch except PDA 25 h. The findings of our study reveal that a combination of pullulanase debranching time (15 h) and autoclaving (121 °C for 20 min) is a great technique that can be used to produce a higher amount of resistant starch in the Jinshu No.17 starch.
