Levels Determination of phenolic compounds and antioxidant activity assay of eggplant belanda fruit (Cyphomandra betacea (Cav.) Sendtn) with visible spektofotometri has been done. Determination of phenolic compounds performed by the method of Folin ciocalteu, while DPPH is used as an antioxidant. The antioxidant activity is determined by its IC50 value. In this treatment gallic acid used as a comparison. The results showed that the levels of phenolic compounds from the sample extract solution is 0.288845 mg / g; 0.29678 mg / g and 0.28964 mg / g respectively. The antioxidant activity determined by IC50 values, where the value of its IC50 was 240.0811 µg / mL; 204.5010 µg / mL; 196.8531 µg / mL.

A study concerning the manufacture of calcium gluconate limestone hill Tui Leopold. Previous limestone samples were identified and determined the levels of calcium. 1 g sample of limestone calcium levels obtained 36,0812 %. In the manufacture of calcium gluconate used limestone samples of 20 g were dissolved in 6 M HCl, filtered and the filtrate was added 6 M NH4OH to pH 10 . Then added gluconic acid 1 M. The precipitate is filtered, washed, dried in an oven at a temperature of 1050 C. The results obtained as 6,2084 g of calcium gluconate. Examination of limestone calcium gluconate include organoleptic examination, solubility, qualitative identification, examination and the melting point of the assay by the method complexometry. In the assay of calcium gluconate from the manufacture of natural limestone samples carefully weighed approximately 0,5 g , 1 g, and 2 g. Of the three differences in weight percentage of calcium gluconate calcium results obtained, weighing 0,5 g to as much as 62,2708 % , 1 g weight as much as 79,9048 %, while the weight of as much as 2 g 101,7232 %. From the results of the assay of calcium gluconate with a sample of 6,2084 g drying results have percentage 101,7232 % with the results of testing the melting point is 2000 C calcium gluconate. It can be concluded natural limestone hill Tui Leopold has a high purity calcium levels that can be made of calcium gluconate.

Analisis Senyawa Fenolat Dan Uji Aktivitas Antioksidan Buah Markisa (Passiflora Edulis Sims) Secara Spektrofotometri Visibel Fithriani Armin; Ermadanis Ermadanis; Roslinda Rasyid

Has done research on the analysis of phenolic compounds and antioxidant activity test on passion fruit (Passiflora edulis Sims) by visible spectrophotometry method. To determine the presence of phenolic compounds in the sample to be identified with iron (III) chloride is characterized by the formation of dark blue color on the sample. Samples were macerated with 96% ethanol, performed three repetitions and the filtrate was concentrated using a rotary evaporator at a temperature of 400 C. Extracts were obtained determined the levels of phenolic compounds using Folin-ciocalteau method and test the antioxidant activity using DPPH method. Standard solution used is gallic acid. Equation linearity gallic acid used in the determination of phenolic compounds in the sample is y = 0.004x + 0.1366 with correlation coefficient (r) = 0.9956 measured at λ max 761.5 nm. the levels of phenolic compounds were obtained on average at the sample was 0.0377% w / w. The average percent inhibition of passion fruit sample solution were counted against the maximum wavelength of 512.0 nm DPPH is 19.8763%. The antioxidant activity of the sample solution of 10 mg is equivalent to 618.9760 mg gallic acid and gallic acid solution IC50 of 1.5604 mg / mL of the sample solution while the IC50 14.4751 mg / mL.
