Abstract
Phytochemical screening of 95% ethanolic extracts from Red Morning Glory (
*QPNPFBǰ
BRVBUJDBǰ
Forsk ) revealed the presence of triterpenoid saponins, flavonoids, leucoanthocyaninǰand
tannins, whereas for water extracts found only tannins. Removal of formaldehyde in shrimps by soaked
in Red Morning Glory extracts for 30 minutes. Analyzed contents of formaldehyde in these samples
by UV-Vis spectrophotometry with reaction ofǰNash’s reagent
which produced yellow complex
compounds. Quantitative analysis was measured at 413ǰnm by linear standard curve using equation of
y = 0.427x +0.0235 (R
2
= 0.995). The removal percents of 95% ethanolic extracts highest values (83.10%),
ethanolic extracts in aqueous (81.58% ǰand water extracts (71.46%), respectively.
