Male infertility has occurred rapidly in the last few decades, primarily in developing countries. An antioxidant, hesperetin is a flavonoid that is found in abundance in orange peels. The aims of this research were to determine the effect of hesperetin on blood sugar levels, spermatozoaquality, and spermatozoa quantity. The research structure included induction of diabetes mellitus and treatment for 8 weeks, followed bydetermination of blood sugar levels, spermatozoa quality, and spermatozoa quantity. Hesperetin has the ability to restore blood sugar levels, spermatozoa quantity, seminiferous tubules diameter, and testicular weight, volume, and germinal epithelial layer thickness with significant difference from the normal control group. Hesperetin did not fully restore spermatozoa motility, viability, and morphology with significant difference from the normal control group, nor from the positive control group. However, overall, hesperetin decreased blood glucose levels, increased spermatozoa quantity, and improved the spermatozoa quality in alloxan-induced diabetes mellitus mice. Dose-dependent activity was observed with the optimum dose at 200 mg/kg body weight.
Free radicals can cause various degenerative diseases such as cancer and cardiovascular disease. Flavonoids have antioxidant abilities that inhibit damage from free radicals. The roselle antioxidant mechanism is associated with high flavonoid content. Red and purple roselles are two varieties of roselle (Hibiscus sabdariffa L.) cultivated in Indonesia. The aim of this research was to analyze the differences in flavonoid content and antioxidant activity in the calyces of two varieties of roselle (Hibiscus sabdariffa L.), red and purple. Total flavonoid analysis and antioxidant activity testing were done by spectrophotometry in the visible region. Total flavonoid content was analyzed by pretreatment with aluminium chloride and sodium acetate. Antioxidant activity was tested with 2,2-diphenyl-1-picrylhydrazyl. The total flavonoids for both red and purple roselle calyces ethanolic extract were 27.55 and 39.18 mg quercetin equivalent per gram. The half maximal inhibitory concentration values obtained for both red and purple roselle calyces ethanolic extract a were 51.59 and 42.17 μg/mL. The total flavonoid content and antioxidant activity of purple roselle calyces ethanolic extract was higher and stronger than red roselle calyces ethanolic extract.
One type of cosmetic or decorative cosmetic preparation is eyeshadow which contains a color pigment applied to the eyelid. The purpose of this study was to find out that kecombrang flower extract can be used as eyelid coloring. From the study to make eyeshadow preparations using dyes extracted from kecombrang flowers, to determine the stability of the eyeshadow by using kecombrang flower extract in storage at room temperature, and to find out whether eyeshadow preparations using extracts from kecombrang flowers cause irritation when used. Eyeshadow preparations from kecombrang flower extract (Etlingera elatior Jack) were made in various concentrations of 15%, 17.5%, 20%, 22.5%, 25% and blank preparations (without using kecombrang flower extract). Physical quality inspection of the preparation includes: color dispersion test (homogeneity), cracking test, and stock stability test. And for other tests carried out polishing tests (homogeneity) and irritation tests. Eyeshadow from kecombrang flower extract also does not cause irritation and is stable in room temperature storage for 30 days. Preparation of kecombrang flower extract with several good concentrations was used as eyeshadow preparations, stable eyeshadow preparations in storage at room temperature within 30 days, and the formulation of eyeshadow preparations using kecombrang flower extract as eyelid coloring did not cause irritation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
