Abstract

Coffee has many health benefits, such as stimulating the central nervous system, with the effect of relieving fatigue, drowsiness, and also in creasing concentration power. How ever, excessiveuse of caffeine can cause heart palpitations, stomachdi sorders, and shaking hands. Caffeine levels in coffee circulating in the market vary, dueto a mixtureofotheringredients. For this reason, the National Standardization Agency (BSN) has set a standard for caffeine content in coffeepowder, whichis 0.455%-2% w/w (SNI 01-3542-2004), so that if there is coffee containing high levels of caffeine, it needs to be decaffeinated. tosuppresstheactivityofcaffeine in thebody. The purpose of this study was to determine the caffeine content of Arabica coffee powder and Robusta coffee. The samples determined were 2 types of arabica coffee powder, namely those obtained from high stems and low stems, and 1 robusta coffee powder. Sampling was carried out purposively, and as says were determined using ultraviolet spectrophotometry after extraction using chloroform. The results showed that the caffeine content of high-stem Arabica coffee powder was 1.675% (16.75mg/g), low-stemmed 0.546% (5.462 mg/g), and 0.818% (8.18mg/g) of Robusta coffeegrounds. In conclusion, the caffeine levels of the three samples determinedmet the requirements of the Indonesian National Standard.

Abstract

Noni fruit (Morindacitrifolia L.) is a medicinal plant that is well known by the people in Indonesia. Noni is efficacious as an immune enhancer, normalizes blood pressure, anti-cancer, analgesic, diabetes mellitus, heart disease, stroke, antimicrobial. To know the characteristics of simplicia and the class of compounds from the noni fruit as well as to analyze the flavonoid compounds contained in the noni fruit using the thin layer chromatography method. The flavonoid compounds were extracted by maceration using ethanol solvent and then the ethanol extract was tested by thin-layer chromatography using 1% HCl mobile phase and spotting with 1 N H2SO4 reagent and methanol pa (1: 1% v/v). Result of simplicia characterization of fruit Noni, obtained 1.32% water content, 38.41 % water soluble extract content, 16.7% ethanol soluble extract content, 6.09% total ash content, and 0.45 acid insoluble ash content. %. Noni fruit simplicia contains chemical compounds of alkaloids, tannins, flavonoids, triterpenoids/steroids, anthraquinones, saponins with phytochemical screening tests. The value of Rf from the analysis of noni fruit flavonoid compounds using the Thin Layer Chromatography method with 3 repetitions is 0.75; 0.68 and 0.62. This indicates the presence of flavonoid compounds in the noni fruit.
