Antioxidative properties of roselle (Hibiscus sabdariffa L.) in linoleic acid model system

A study was conducted to determine the antioxidative properties of roselle (Hibiscus sabdariffa L.) methanol extract by monitoring the formation of dieneconjugated compounds and thiobarbituric acid reactive substances (TBARS) in linoleic acid model system. The properties were compared to those of b...

A total of 200 parts per million (ppm) of the extract inhibited more than 85 per cent of dieneconjugated compounds after seven days of incubation at 40○C.
