Muntingia calabura is broadly cultivated and has become a common roadside tree in Indonesia that is known as "Kersen," or cherry. The current study aimed to determine the activities of the phytochemical constituent (i.e., phenolic and flavonoid total contents) with various concentrations of ethanolic extract of M. calabura leaves (EEMC) to determine the best one and the in vitro antioxidant activities and quercetin content using TLC Densitometry. The extraction was carried out by maceration with various concentrations of ethanol (96% v/v; 70% v/v and 50% v/v) to obtain the ethanolic extract of Muntingia calabura, L leaves. The determination of Quercetin was conducted by Thin Layer Chromatography (TLC) densitometry, and the total phenolic was analyzed with reagent Folin-Ciocalteu while the flavonoid content we identified by applying the colorimetric method. The antioxidant capacity was measured using the radical scavenging assay of 1,2-diphenyl-2-picrylhydrazyl (DPPH). The phytochemical study showed that phenolics, saponins, tannins, and flavonoids were present in all EEMC. The extract obtained by 96% ethanol showed the highest total antioxidant activity, reducing power and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity. The same extract also exhibited the highest flavonoid content. However, the extract obtained by 70% ethanol showed the phenolic content, and the highest quercetin content was obtained by using 50% ethanol. The result from the EEMC analysis indicated that Muntingia calabura leaf extract contains essential bioactive compounds and shows potential as a source of antioxidants in M. calabura which uses 96% ethanol solvent and has the highest quercetin content in M calabura using 50% ethanol solvent.

Seminal vesicles were collected from 60 heads of Bulls which butchered in slaughter house (RPH) Yogyakarta. The aims of this study are knowing the relationship between body weight, age, fluids volume and concentration of prostaglandin F2 α (PGF2α) in seminal vesicle of beef cattle. Those seminal vesicles were gathered from bulls which recorded its body weight and age then measured its seminal vesicles for weight, fluids volume and PGF2α levels. The PGF2α level was measured by Enzyme-Linked Immunosorbent Assay. Statistical analysis was performed using one way – analysis of varian, regression and correlation with P<0.05. Body weight of bulls showed positive correlation with the weight of seminal vesicle and its fluids volume. However, PGF2α levels were not correlated with the body weight of cattle. Weight of seminal vesicles also exhibited positive correlation with volume of vesicle fluids but no correlation with PGF2α levels. Based on the age of bulls, there were no correlation withthe weight of seminal vesicles, seminal fluids volume and PGF2α levels. Those result indicated that the weight and fluids volume were affected by the body weight of bulls altough the PGF2α levels have a standard of developmentwhich seems affected by other factors such as concentration of androgen hormone.

ABSTRACTA study of optimization of red cabbage (Brassica oleracea.L. var. capitata f. rubra) gel extract formula has been performed by using Simplex Lattice Design (SLD) method and antioxidant activity of the formula gel was also evaluated by using in vitro method.The red cabbage was extracted by soxhletation by using ethanol 96% followed by optimization of red cabbage extract in antioxidant gel preparation used SLD method by Design-ExpertÂ® software version 7 (DX7) and determination of its IC50 used UV-Spectrophotometry. The stability of optimum gel formula is seen through comparison of physycal properties at the beginning and after four weeks storage used ANOVA, with a 95% significant level. Optimum gel formula of red cabbage extract obtained in the proportion of Metolose 3,883%, propilen glikol 13.5%, Tween 80 1.117%. The evaluation results of optimum gel formula of red cabbage extract is the surface area of gel dispersive of 38.99 Â± 3.27cm2; viscosity gel dPa.s of 295.56 Â± 1.93 and viscosity change 3.89 Â± 0.96%. From the results of statistical analysis of one t-test sample was concluded that there was no difference between the prediction price of software with the observation result (p> 0.05). The IC50 test result of the optimum formula of red cabbage extract gel was 257.25 Â± 0.35 Âµg / mL. The testing result of the physical stability of the optimum formula of red cabbage extract gel suffered a pH decrease after 4 weeks of storage (p <0.05).
