Phytochemical-enriched edible greens, sweet potato leaves (Ipomoea batatas L.), have become popular due to potential health benefits. However, the phytochemical contents in sweet potato leaves and their subsequent change over harvest stages and growth condition are mostly unknown. In this study, the anthocyanin profile and content in leaves of four sweet potato cultivars, i.e., white-skinned and white-fleshed Bonita, red-skinned and orange-fleshed Beauregard, red-skinned and white-fleshed Murasaki and purple-skinned and purple-fleshed P40, were evaluated. Fourteen anthocyanins were isolated and identified by HPLC-MSI/MS. The most abundant was cyanidin 3-caffeoyl-p-hydroxybenzoyl sophoroside-5-glucoside, which comprised up to 20% of the total anthocyanins. Of the young leaves (1st and 2nd slip cuttings), Bonita contained the highest anthocyanin content followed by P40. Of the mature leaves (vine stage), Beauregard had the greatest anthocyanin (592.5 ± 86.4 mg/kg DW) and total phenolic (52.2 ± 3 mg GAE/g DW). It should be noted that the lowest anthocyanin and total phenolic content of shoots were found in P40, while tubers of P40 contain the highest content of each. Furthermore, the increase in leaf anthocyanin content over the growth stages that was observed in three of the cultivars but not in P40. No significant difference of anthocyanin content was found in Beauregard leaves grown in the high tunnels when compared with that in the open field. This study demonstrated for the first time that anthocyanin levels were significantly changed in response to various growth stages but not high tunnel condition, indicating that the effect of anthocyanin biosynthesis in sweet potato leaves is highly variable and genotype specific.

Natural sources of antioxidants are derived from fruits, vegetables and wine, whilst artificial supplements are from teas and spices. Sweet potato (Ipomoea batatas) is an excellent natural source of vitamins and minerals, and likely a great source of antioxidant. The objective of this study  is to analyze the antioxidant activity of orange sweet potato (Vitato) and  purple sweet potato (All purple), prepared as heat dry and  moist heat for 30 minutes at 100oC. All the samples were obtained from Pasir Puteh and MARDI Telong, Bachok, Kelantan, respectively. Both samples were soaked into methanol to obtain the crude extract prior to analyzing for antioxidant activity by using 2, 2-diphenyl-1-picryl hydrazyl (DPPH). IC50 values of dry heat and moist heat Vitato were 0.40mg/L and 0.20mg/L while dry heat and moist heat, All purple were 0.32mg/L and 0.19mg/L, respectively. Both moist heat samples enjoyed higher scavenging activities compared to dry heat samples. However, the All purple sample of moist heat is the most superior one. Significant difference of IC50values between dry heat and moist heat sample differ significantly. Thus, this study clearly demonstrated that moist heat sweet potato exhibited  excellent increase in antioxidant activity.

Background: Fruits, vegetables and legumes for their complex carbohydrates, dietary fiber and micronutrients, should form an essential part of every diet. In order to give good dietary advice to diabetic patients, it is necessary to know the glycemic index of foods commonly consumed locally. The objective of this study was to determine the Glycemic Index (GI) and Glycemic Load (GL) of commonly available and consumed Guava (Psidium guajava), Watermelon (Citrullus vulgaris), Gungo (Cajanus cajan), Papaya (Carica papaya) and tomato (Solanum lycopersicum) in Jamaica. Methods: Ten (10) healthy Jamaican subjects (5 males, 5 females) with mean age 30 ± 2 years and mean BMI 25 ± 1 kg/m2 were recruited to the study. Using a non-blind, crossover design trial, the subjects consumed 50 (or 25) grams of available carbohydrate portions of glucose (standard food) and test foods after an overnight fast and their serum glucose levels were determined at 0, 15, 30, 45, 60, 90 and 120 minutes after the consumption of each test food. Glucose was tested on three separate occasions, and the test foods once. The GI value was calculated geometrically by expressing the Incremental Area Under the Blood Glucose Curve (IAUC) for the test foods as a percentage of each subject's average IAUC for the standard food. Results: The results indicated that the IAUC for Watermelon (95 ± 11) was significantly higher (p<0.05) than that of Tomato (37 ± 12), and Gungo (58 ± 13). The differences in IAUC of Watermelon (95 ± 11), Guava (83 ± 27) and Papaya (80 ± 7) were not statistically significant. Similarly, there was no significant difference in GI among the samples studied. Conclusion: Tomato, Gungo, Papaya Watermelon and Guava were shown to have low glycemic index and glycemic load values.

Aims: This study was conducted specifically to develop a low cost rapid plantlet multiplication process easily affordable for farmers to enable them speedily generate plantlets for their farms from mini tubers of sweet potato variety, TIS 87/0087. Study Design: The experimental design was a completely randomised design with three replications. Analysis of variance was used (P=.05) to test treatment effects in a completely randomized design and mean comparison was by LSD. Place and Duration of Study: The study was carried out between February and April 2019 in the plant culture laboratory of the Department of Plant Science and Biotechnology, Rivers State University, South-South, Nigeria. Methodology: Mini tubers of sweet potato (Ipomoea batatas, L.) were preconditioned by soaking in a 1:10 ratio of natural substance to water for 12 hours before planting in soil. The natural substances comprised coconut water, grapefruit juice and honey with water as control. Results: Mini tubers primed with grapefruit juice and coconut water sprouted significantly earlier (P=0.05) (7 days and 10 days respectively) than the control (water) which sprouted after 19 days. However, there was no significant difference in time to sprouting between mini tubers primed with honey (16 days) and the control (19 days). Mini tubers primed with grapefruit juice, coconut water and the control did not differ significantly (P=.05) in the number of initial plantlet sprouts but mini tubers primed with honey had significantly lower initial sprouts than others. On average, coconut water primed mini tubers produced significantly higher (P=.05) total number of regenerated plantlets compared to the other treatments and continued regeneration of plantlets longer than other treatments. Coconut water regenerated almost 3times the number of plantlets regenerated by mini tubers soaked in water. Mini tubers primed with honey stopped sprouting after 29 days which was significantly earlier (P=.05) than those primed with grapefruit juice (38 days), water (46 days) and coconut water (51 days). Conclusion: This study found that mini tubers of sweet potato after a preconditioning treatment by soaking in dilute coconut water (1:10 coconut water : water ratio) for 12 hrs before planting regenerated almost 3times the number of plantlets regenerated by mini tubers soaked in water for the same period.
