Antifungal Activity of Red Dragon Peel (Hylocereus polyrhizus)ⓒ Rudi Hendra et al 2020 IOP Conf. Ser.: Mater. Sci. Eng. 833 012014
STATE THE HYPOTHESIS (In if-then format):
Plants, when extracted, can produce dyes and the extracts have been used for different purposes such as the textile or food industry [1]. One potential plant that can be used as a natural dye is dragon fruit (Hylocereus cacti) or by another name Pitaya. Wybraniec and coworkers reported that dragon fruit has a potential as a source to produce red pigment and it's called betalains [2]. Betalain is a water-soluble pigment that gives color to flowers and fruits. Betalain pigments are divided into two groups, namely betacyanin which produces purplish red and betaxanthin which produce yellow-orange colors [2, 3].
In the dragon fruit peel, it is also containing pigments which are usually only discarded as food waste and have not been used optimally. This is very unfortunate because the fruit of the dragon fruit itself has…

Then, 2) insoluble cell contents were removed by centrifugation at 4,000 x g for approximately ten minutes. The ruptured cells (lysate) after centrifugation had a total volume of 0 mL and a 1.0 mL aliquot was set aside for further analysis. The following data was obtained from the 1.0 mL aliquot to quantify the protein amount and purity: The absorbance at 410 nm of the aliquot was 0.460 (1 cm pathlength). The absorbance at 595 nm from a 1.0 mL Bradford Assay solution that was diluted by 250-fold from the aliquot was 0.681 (1 cm pathlength). Using the information given, Calculate the total protein amount in mg from the absorbance at 595 nm.
