Glibenclamide has the biopharmaceutics classification system (BCS) class II which has high permeability and low solubility. The solubility of glibenclamide can be enhanced by forming solid lipid nanoparticles (SLN). This research has the aim to prepare and characterize SLN loading glibenclamide. The glibenclamide SLN formula was composed by using the liquid lipid as virgin coconut oil (VCO), PEG 6000 as a solid matrix, tween 80 with various concentrations as a stabilizer, and PEG 400 as co-surfactant. Characterization was conducted by determining the encapsulation efficiency (%EE), size measurement, particle size distribution, and zeta potential of SLN glibenclamide. SLN formation was also tested for its physical stability based on the heating-cooling cycle method. The optimum formula was obtained at the concentration of tween-80 of 1 mg/mL yielding the %EE value of 60.6194%, and pH 6.01. The results of particles diameter analysis were 175.5 ± 10.07 nm with a polydispersity index (PDI) of 0.1270, and zeta potential of +5.9 mV respectively. Stability testing by the heating-cooling cycle method has shown the instability of the SLN glibenclamide form under extreme temperatures and mechanics. It could be concluded that the results of characterization of glibenclamide SLN showed appropriate physical properties for nanoparticulate formulation.

Antidiabetic activity test of ethanol extract of seri leave (Muntingia calabura L.) rats induced by alloxan has been done. Male wistar albino rats are used as animal models which divided into 6 groups, normal group (aquadest), negative control group (Na CMC 0,5%), positive control group (glibenclamide0,43 mg/200 g of BW), and 1, 2, and 3 treatment groups (ethanol extract of seri leave 65, 130, dan 260 mg/kg of BW). Rats blood glucose level after induced intraperitoneally by alloxan130 mg/kg of BWcan be stated as diabetes when >200 mg/dL. Preprandial blood glucose levels are measured using DTN-410-K photometer, on day 0, 5, 10, and 15. The average result of AUC 0-15 and percentage of decreasing blood glucose level for positive control group are 2732,5 and 37,43%, and 3 treatment groups (65 mg/kg of BW, 130 mg/kg of BW, and 260 mg/kg of BW) 3105 and 28.90%; 2962.5and 32.16%; 2810 and 35.66%. These points indicated that the ethanol extract of seri leave have an antidiabetic activity and there is no significant difference compared with glibenclamide (p<0.05). Percentage of blood glucose decrease level the third treatment group so there is no significant difference compared with positive control group. According to the relation between percentages of blood glucose decrease level with dose, value of ED 50 of ethanol extract of seri leave is 692.424 mg/kg of BW.

Context: Dillenia ochreata is a medicinal plant used traditionally for scabies treatment. D. ochreata leaves contain secondary metabolites of triterpenoids, phenolics, and steroids that have the potential to accelerate the wound healing process. Aims: To determine the effect of the ethanolic extract of D. ochreata leaves on the speed of healing of burns and incisions. Methods: The test animals were divided into six groups: a positive control group (1% silver sulfadiazine ointment for burns and 10% povidone-iodine ointment for wound incision), a negative control group, and four treatment groups with an ointment concentration of 2.5, 5, 7.5, and 10%. Burns were made using a heated iron plate, and incision wounds were made using a sterile scalpel blade with a length of 3 cm. Parameters observed included burn area, incision length, percent recovery, and histopathology. Results: It was observed that the 10% concentration of D. ochreata leaf ethanol extract showed the best results in healing burns and incision wounds, with 100% healing within 12 days for burns and five days for incisions. The treatment group had a significantly different wound healing activity (p<0.05) compared with the negative control and was not significantly different (p>0.05) from the positive control. Conclusions: D. ochreata leaf ethanol extract (10%) could accelerate the healing of burns and incisions.

Preparation of petai pods extract (Parkia speciosa) into ethosome aim to increased penetration through the skin. The method of cold is used in preparing petai pods extract encapsulation by ethosome with variation in concentration of  soya lecithin, propylene glycol, and ethanol. The proportion of optimum formula ethosome consisted were 0,2 g soya lecithin, 1 ml propylene glycol, and 4 ml ethanol that response values obtained pH of 4,74, viscosity of 0,950 cP, %EE of 74,326%, and stability of 7,288%. The resulted of optimum formula obtained were PDI of 0,23, zeta potential of -7,5 mV, and particle size of 818,7 nm. Ethosome showed spheric particle using Transmissin Electron Microscopy. The diffusion analysis showed highest on ethosome of petai pods extract (9,525%) than petai pods extract (5,466%). The interaction study used FTIR show no chemical interaction extract pods and ethosome components

Objectives Artocarpus is a tropical plant known for its high concentration of secondary metabolites, especially flavonoids and phenolics. This study aims to evaluate the potential use of ethanol extracts obtained from three species of Artocarpus (Artocarpus altilis, Artocarpus champeden, and Artocarpus heterophyllus) as gastroprotective agents. Methods The gastroprotective potential of the extracts at concentrations of 100, 200, and 400 mg/kg BW was studied in an animal model induced by absolute ethanol. The animals were subjected to extract pre-treatment for 14 days. Subsequently, the gastroprotective potential was evaluated based on the area of the lesion, the volume of gastric fluid, gastric pH, total acidity, gastric wall mucus content, and microscopic lesions. Results There was a significant decrease in the lesion area and gastric fluid volume in the animals that received pre-treated extracts of A. altilis, A. Champeden, and A. heterophyllus, as well as a significant increase in the pH and gastric wall mucus secretion when compared to the ethanol group (p<0.05), rather than the omeprazole or the normal group (p>0.05). Both macroscopic and microscopic examinations revealed a significant decrease in necrotic lesions. Conclusion Extracts of A. altilis, A. Champeden, and A. heterophyllus are effective in lowering the risk of peptic ulcers since they have the potential to be used as natural gastroprotective agents.
