Abstract

A research on the determination of level of vitamin C in Red Dragon fruit syrup by conducting storage time variety  have been done in normal condition, so that it can be consumed. Analysis process has been conducted by Iodimetry titration method through the step of dragon fruit syrup made by variety of storage time 0 until 20 days. The result showed that high level of vitamin C was 0.03136 % on the beginning day, and the low level was 0.00141 % on the 20th, therefor can be summaries that vitamin C on dragon fruit syrup product can lasted while 20 days only in the normal condition. Furthermore for organoleptic test of the dragon fruit syrup product can lasted  on the beginning day until day of 15th and on the day of 16th or more that respondents declare of dragon fruit syrup product was not feasible to consumed.

Abstract

Test of antioxidant activity of methanol extract and its fractions from leaves of Knobweed (Hyptis capitata Jacq.) were carried out. This research was conducted to determine antioxidant activity in the fractions resulting from column chromatography separation. Antioxidant activity test was carried out by DPPH method while phytochemical was carried out by test colour of TLC method. The results of the first column chromatographic separation produced 18 fractions. The results of the first column antioxidant activity test showed that the value of antioxidant activity ranged from 0.923-81.849% at a sample concentration of 100 ppm. The second column chromatographic separation was carried out in fraction 16. The results of the second column antioxidant activity test produced 18 fractions. The results of the second column antioxidant activity test showed that the value of antioxidant activity ranged from 10.384-59.769% at a sample concentration of 50 ppm. The second column antioxidant activity test produced fraction 15 and fraction 16 showed IC50 values ??of 40.321 and 56.812 ppm respectively. Phytochemical test results showed that fraction 15 and fraction 16 contained alkaloid compounds, flavonoids, polyphenols and steroids/terpenoids.   Keywords:   Antioxidant, knobweed (Hyptis capitata Jacq), column chromatography, antioxidants, DPPH, secondary metabolites

Abstract

One type of Bajakah that is believed by local people especially in the area of Muara Badak, KutaiKertanegara Regency, has the efficacy of anticancer drugs, is Uncaria nervosa Elmer. The purposes of this studywere to determine the content of secondary metabolites and the toxicity of the extracts of the bark and root of thewood of Bajakah (U. nervosa). From the results of phytochemical tests showed that both bark and root woodcontain secondary metabolites of alkaloids, flavonoids, terpenoids, and phenolics. Moreover, based on the result ofthe mortality test for Artemia salina shrimp larvae, it showed that both the bark and wood of the roots are verytoxic with LC50 values of 1.76 and 2.66 ppm, respectively. Both of these extracts are potentially cytotoxic to cancercells.

Abstract

Phytochemical test and antibacterial activity of Macaranga lamellata Whitmore have been done. This research aims to find out the secondary metabolites using Thin Layer Chromatography (TLC) and to determine antibacterial activity by paper disc method from methanol extract on Macaranga lamellata Whitmore leaf. Based on the results obtained from phytochemical tests, it was known that methanol extract contains alkaloid, flavonoid, polyphenol and terpenoid/steroid compounds. Antibacterial activity obtained Minimum Inhibitory Concentration values from methanol extract for Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422 at 0-0.5%.
