Abstract

Polyphenols, flavonoids, triterpenoid and VitaminC from Clinacanthus nutans were extracted by ultrasonic-assisted ethanol extraction. The optimal extracting conditions were established as ethanol as solvent, ultrasound treatment time 35min, solid-liquid ratio 1:45 (g/ml), ethanol concentration 70% and ultrasound power 90W. Results revealed that ultrasound treatment time exert a significant effect on polyphenols and flavonoids, whereas ethanol concentration plays a key role in the extraction of triterpenoid and VitaminC. Under these conditions: polyphenols 8.555mg/g, flavonoids 39.567mg/g, triterpenoid 15.216mg/g, vitaminC 0.606mg/g. This study shows that ultrasonic-assisted ethanol extraction is an efficient technology to extract bioactive substances from Clinacanthus nutans could potentially be a resource for natural antioxidants.
