Background: Ipomoea batatas (L.) Lam. (I. batatas) is a root native from South America that is characterized by its antioxidant, antimicrobial and anti-inflammatory properties. These properties contribute to the wound healing process. Objective: To evaluate the healing activity of a gel based on I. batatas on dermal wound healing in mice. Material and methods: An acid ethanolic extract (1.5 N hydrochloric acid: Ethanol 96 {\textdegree} 15:85, v / v) was prepared with the peels of the roots of I. batatas "purple sweet potato", which was incorporated into the formulations 0.5\% and 1\% gel. Mus musculus Balb / c with induced injury were distributed in four experimental groups: Group I (Control), which did not receive any treatment. Group II (Gel base), Group III (Gel I. batatas 0.5\%) and Group IV (Gel I. batatas 1\%) received the daily administration of topical treatments for 14 days. Wound closure was determined during the experimentation time, then they were euthanized with sodium pentobarbital 60 mg / kg / pc v.ip. to obtain skin samples for histopathological analysis. Results: Group IV shows a higher percentage of wound closure, which is also evidenced in histopathological changes. Conclusions: The 1\% gel based on the ethanolic extract of the peels of the roots of Ipomoea batatas (L.) Lam. they show healing activity in wounds induced in mice, being the most effective treatment.

Background: Some edible plants are promising to control blood sugar level. These plants contained phenolic substances that suggested to be able to inhibit dipeptidyl peptidase 4 (DPP IV). Objective: The objective of this study was to investigate the inhibitory effect of several selected Indonesia plants on inhibiting of DPP IV activity and to determine the total phenolic content of the most active extract. Methods: Twelve Indonesia edible plants were macerated using 80\% ethanol at room temperature. DPP IV activity was evaluated by using glycyl-prolyl-7-amino-4-methyl coumarin (Gly-Pro-AMC) substrate and the inhibitory effect of extracts were determined based on the level of free AMC group by measuring its fluorescence on excitation wavelength 350-360 nm and an emission wavelength 450-465 nm using a microplate reader. Total phenolic contents of the active extracts were determined with Folin-Ciocalteu 1:4 on 765 nm using microplate reader. Total anthocyanins from extract were determined using the pH differential method. Results: Among the tested samples, the extract of Ipomoea batatas roots at a concentration of 10 μg/mL showed the highest inhibition, followed by Cajanus cajan leaves and Gnetum gnemon rind, with percentage inhibition of 28.8, 24.9 and 24.1, respectively. I. batatas extract have an IC50 value of 65.53 μg/mL, while the IC50 value of the positive control Sitagliptin 9.37 μg/mL. Total phenolic content from the extracts of I. batatas, C. cajan and G. gnemon rind extract were 279.3; 152.8; and 141.3 mg GAE/gram, respectively. Total anthocyanin from I. batatas extract was 462.14 mg cyanidin- 3-glucoside/L. Conclusion: The extract of I. batatas showed the highest inhibition on DPP IV among other plants investigated and showed high content of phenolic compound and anthocyanin that correlated with activity as inhibitor DPP IV.
