Abstract :
One of the ways to prevent being infected with COVID-19 is by
increasing endurance, such as consuming foods and drinks that contain
antioxidants. Temulawak contains flavonoids which are a source of antioxidants.
The purpose of this study was to determine the total flavonoid levels from the
variation of boiling time of temulawak.
This research determined the total flavonoid levels from the variation of
boiling time for temulawak 5 minutes, 10 minutes, 15 minutes and 20 minutes. Each
variation of the boiling time was determined using a Uv-Vis spectrophotometry
method.
The average total flavonoid level in the 5th minutes treatment had a
level of 6.5536 mgQE/100ml with %KV value of 0.0000440%, the 10th minute
had a level of 7.1813 mgQE/100ml with %KV value of 0.0000402%, minutes the
15th had levels of 10.0399 mgQE/100ml with %KV value of 0.0002294%, while
the 20th minute the levels were 11.3721 mgQE/100ml with %KV value of
0.0000406%. Furthermore, the Kruskal-Wallis test the significant value was
0.015 ? 0.05, it can be concluded that there was a significant difference from the
variation in the duration of boiling temulawak. The length of heating time can
affect the levels of flavonoids contained in the stew.
