Abstract

Anthocyanin is one of the many compounds in dragon fruit skin that can be used as an antioxidant. Dragon fruit skin can also lower blood glucose levels. The fact that cases of diabetes mellitus are increasing every year shows that this disease needs serious treatment. This study aims to make dragon fruit skin extract formulated in the form of granules and make dragon fruit skin extract granules that meet the requirements as natural food coloring and to determine the content and effectiveness of dragon fruit skin extract (Hylocereus polyrhizus) which can lower blood glucose levels. This research method is experimental. The One Way Anova test and the Tukey HSD post-hoc test were used to analyze the data. The outcomes showed that there were 9 granule recipes that met the assessment test necessities. After being induced by 20% fructose solution, the glucose level study revealed that the treatment of dragon fruit skin extract at 100, 200, and 400 mg / kgBW was able to lower blood glucose levels in test animals. Winged serpent natural product skin concentrate can be formed as granules. Equations 2 and 3 produce the best tone. The consequences of the review reasoned that winged serpent natural product skin remove (Hylocereus polyrhizus) at dosages of 100, 200 and 400 mg/kgBW was viable in decreasing blood glucose levels in guinea pigs prompted by 20% fructose arrangement and a portion of 200 mg/kgBW gave an impact of lessening blood glucose levels that was practically equivalent to the positive control.

Abstract

Facial wash is a facial cleansing soap that can clean oil and cosmetics that stick to the face. Usually facial wash has a low pH or close to the skin's normal pH, namely 4.5-6.5 and contains milder detergent. Researchers are to determine which celery leaf extract (Apium graveolens L.) is being evaluated as a facial wash preparation and to determine which facial wash preparation has inhibitory power for the growth of Staphylococcus aureus bacteria. This research is experimental using the maceration method. The sample used in this research was 10 kilograms of celery leaves. Results : Testing the pH of the celery leaf ethanol extract facial wash gel preparation for each F0, F1, F2 and F3 showed that the pH of the celery leaf ethanol extract facial wash gel preparation decreased due to the presence of acid compounds in celery leaves, causing the pH to decrease slightly but still within the pH range. topical, namely 4.5-7.0 and the pH of the celery leaf ethanol extract facial wash gel preparation above shows a relatively neutral pH which is still safe for the skin. The facial wash gel preparation of ethanol extract of celery leaves (Apium graveolens L.) has an inhibitory zone containing Staphylococcus aureus bacteria in K(+), K(-), F1 (5%), F2 (10%) and F3 (15%) with strong inhibition zone category. Researchers found that the ethanol extract of celery leaves can be formulated in the form of a facial wash gel. It is recommended that further research be carried out on the effectiveness of celery leaves with different concentrations and methods.

Abstract

Facial skin often faces issues such as acne, dullness, and dryness. Sheet masks are one of the cosmetic care products that can help maintain facial skin hydration. Noni leaves (Morinda citrifolia L.) contain secondary metabolite compounds such as alkaloids, tannins, saponins, and flavonoids, which can act as antioxidants.  To determine whether noni leaf ethanol extract can be formulated into a sheet mask preparation and its effectiveness as a moisturiser. The research involved several steps: plant identification/determination, sample collection, extraction using the maceration method with 70% ethanol solvent, formulation of the sheet mask preparation, and evaluation, including organoleptic tests, homogeneity, pH, stability, irritation, and moisture effectiveness testing using a skin analyser. Sheet mask preparations with 5%, 7%, and 10% concentrations were found to be thick, homogeneous, with pH ranging from 4.42 to 5.72, non-irritating, stable during storage, and increased skin moisture by 78.94% for F1, 84.0% for F2, and 85.15% for F3. Noni leaf ethanol extract can be formulated into sheet mask preparations and is effective in moisturising the skin. Keywords: Noni leaf extract, sheet mask, moisture.
