Abstract: Roselle (Hibiscus sabdariffa L.) has been broadly utilized in nourishment industry, particularly its petal part. Notwithstanding, the roselle seeds are considered as waste despite the fact that it was conceivably recognizable as cancer prevention agent sources. The point of this investigation was to decide the best parameter (term and dissolvable) for removing Roselle (Hibiscus sabdariffa L.) seeds by a beat ultrasonic-helped extraction. The cell reinforcement exercises of ultrasonic-helped Roselle (Hibiscus sabdariffa L.) seeds were assessed by a 2,2- diphenyl-1-picrylhydrazyl (DPPH) radical rummaging limit test, 2,2′- azino-bis(3-ethylbenzothiazoline-6-sulphonic corrosive) (ABTS) radical searching limit examine, ferric diminishing cancer prevention agent control (FRAP) measure, and – carotene fading hindrance test. Add up to phenolic content (TPC) and aggregate flavonoid content (TFC) assessments were done to decide the phenolic and flavonoid substance in Roselle (Hibiscus sabdariffa L.) seeds separate. The outcome displayed that the best extraction parameter utilized 80% ethanol for 10 minutes.
