Abstract

Antioxidants can bind free radicals, inhibit oxidative stress, stimulate oxygen and tighten the skin so as to prevent premature aging. An increase in the number of free radicals, an increase in age, and excessive exposure to ultraviolet light can accelerate the aging process or cause premature aging. Premature aging can be prevented by using cosmetics that contain natural antioxidants derived from plants. There are many herbal plants that are empirically used by the Baduy community as potential antioxidants. Proof of antioxidant activity can be done by testing the effects on each herbal plant conducted by several previous researchers. The purpose of this article is to provide information about which plants have the potential as antioxidants as cosmetic raw materials through journal literature searches in electronic databases. Some herbal plants in Baduy outside are papaya, cat whiskers, miana, weeds, kencur, guava, red ginger, betel nut, secang and kecombrang. Secondary metabolites in plants that are most influential as cosmetics include flavonoids and phenolics.

Abstract

Kersen leaves (Muntingia calabura L.) are plants that contain many secondary metabolites, one of which is flavonoids that can act as antioxidants. This study aims to determine the total content of flavonoids which also have the potential as antioxidants in cherry leaves using the DPPH method (2,2-diphenyl-1-picrylhidrazyl) with various filters, namely 70% ethanol, ethyl acetate and n-hexan. Testing of total flavonoid content was carried out using AlCl3 reagent and measured using spectrophotometry at a wavelength of 422 nm. Antioxidant activity testing was measured at an absorption wavelength of 516 nm. The results showed the total flavonoid content of 70% ethanol filter leaf extract as much as 8.13 (mgQE/g), ethyl acetate as much as 8.32 (mgQE/g) and n-hexan as much as 18.96 (mgQE/g). antioxidant activity of cherry leaves using DPPH method (2,2-diphenyl-1-picrylhidrazyl) with filter variations. 70% ethanol extract of cherry leaves has an IC50 value of 7.56 μg/mL, ethyl acetate extract with an IC50 value of 36.05 μg/mL, and n-hexan extract with an IC50 value of 21.33 μg/mL. From the results obtained it can be concluded that the highest antioxidant activity is contained in 70% ethanol extract of 7.56 μg/mL.

Abstract

The Synergistic of antibacterial is an interaction of two antibacterial agents that produces a greater inhibitory effect on bacteria, compared to the individual antibacterial effects of the two agents. The purpose of this study was to determine the synergistic effect of anti-bacterial extract of sapodilla fruit (Achras zapota L.) and water gourd (Lagenaria siceraria (Molina) Standl.) extract against Salmonella typhi bacteria. Extraction of sapodilla fruit and water gourd fruit was carried out by maceration method using 96% ethanol (1:10). Determination of the value of the minimum inhibitory concentration (MIC) of anti-bacterial sapodilla manila fruit and water gourd fruit was carried out by the checkerboard assay method using a 96 wells microplate by calculating the Fractional Inhibition Concentration Index (FICI) value. The results showed that the single MIC value of sapodilla manila fruit and water gourd fruit respectively are 50 mg/mL and 100 mg/mL. The interaction between the two is expressed as a Fractional Inhibitory Concentration Index (FICI) with a value of 1.5. The FICI values ​​indicate different antibacterial effects of the combination of sapodilla fruit and water gourd fruit against Salmonella typhi.

Abstract

Aging is an unavoidable physiological process. The process of premature aging is prevented using natural anti-aging cosmetics derived from plants. Cosmetics can be used as anti-aging products. Therefore, plants can be used as substitutes for anti-aging chemicals with fewer side effects. There are many herbal plants that are empirically used by the Baduy community and have potential as anti-aging agents with tyrosinase inhibitory and antioxidant activities. Evidence of anti-aging activity can be obtained by testing the effects of each herbal plant, which has been conducted by several researchers previously. The purpose of this article is to provide information on which plants have the potential as anti-aging agents for cosmetic raw materials thru a literature review of journals in electronic databases. The results obtained from several plants such as Carica papaya L., Kaempferia galanga, Psidium guajava, Zingiber officinale var. Rubrum, Piper bettle, Caesalpinia sappan L, and Etlingera elatior (Jack) R.M. Sm have tyrosinase inhibitory activity. Orthosiphon stamineus B., Coleus scutellarioides (L.) Benth, and Imperata cylindrica (L) Beauv., the cogongrass plant, use an antioxidant approach as anti-aging. In conclusion, all herbal plants from the Baduy tribe have the potential as raw materials for anti-aging cosmetics
