Abstract

Introduction: Vitamin C is one of the nutrition acted as a antioxidants and effective addres free radicals can be destructive cells or tissue. Fruits are a source of vitamins C, which is a dragon red. Part of the dragon red during this rarely used is the skin. The dragon fruit is very useful to health, but in fact only thought of as waste farming has yet to be used as a good. This study aims to determine comparison levels of vitamin C on the flesh and the dragon red (Hylocereus polyrhizus) with a method spectrophotometry UV-Visible. Method: This type of research using the method of true experimental reseach stage includes preparation of samples, qualitative test,quantitative test, making the solution of the parent raw materials, determination of wavelength of vitamin C and manufacture of the calibration curve. The sample of this study is the flesh and the dragon red (Hylocereus polyrhizus). Results: Based on the results revealed that the fles and the dragon red (Hylocereus polyrhizus) contain vitamin C. Discussion: Levels of vitamin C on the flesh the dragon red of 0.05888 mg/mL and The levels of vitamin C on the skin the dragon red of 0.02533 mg/mL .

Abstract

Introduction: Basil leaf (Ocimum basilicum L.) is one of the most accessible natural plant in Asia such as Indonesia. Basil leaf vegetation contains a lot of flavonoid compounds and essential oils that have the effect as antibacterial because it can inhibit the growth of bacteria Streptococcus mutans cause dental caries. Streptococcus mutans is a round gram-positive bacteria that typically form pairs or chains during its growth. The purpose of this research is to know the antibacterial effectivity of ethanol extract of basil leaves (Ocimum basilicum L.) on the growth of Streptococcus mutans bacteria.This research was conducted with laboratory experimental research method. Basil lean ethanol extract was prepared by using maseration extraction method. Method: The method used in the inhibitory test using diffusion of the disc with 5 samples in each treatment group. The sample consisted of 5 treatment groups, ethanol extract of basil leaves with concentration of 100%, 80%, 60%, 40% and 20%. Result: The result of this study showed that ethanol extract of basil leaves with 100% concentration had inhibitory power of 10,26 mm (strong category), 80% of 9,65 mm (medium category), 60% by 8,12 mm (medium category), 40% by 7,33 mm (medium category), and 20% by 6,90 mm (medium category). Conclusion: The conclusion of this research proves that basil leaf ethanol extract has antibacterial power agains Streptococcus mutans bacteria with effective concentration is 100% with strong category equal to 10,26 mm.
