This study attempts to determine the effect of drying and extraction methods on the antioxidant capacity, phenolic
compounds, and betalain pigment of Alternanthera sessilis red. Evaluation of extraction yield showed that superheated
steam drying exhibited a higher yield than freeze drying. A combination of superheated steam drying and ultrasonic-assisted
extraction resulted in the highest 2,2-Diphenyl-1-picrylhydrazyl radical scavenging activity (39.48%). Ferric reducing
antioxidant power analysis revealed that ultrasonic-assisted extraction enhanced the antioxidant capacity (878.86 mg Trolox
equivalents/100g dried sample) of freeze-dried Alternanthera sessilis red on par with superheated steam dried sample. The
increase in the concentration of major phenolic compounds was also reported in all superheated steam drying samples
(gallic acid: 1556.98 -1715.75 mg/100 g dried sample; vanillic acid: 217.21 - 230.41 mg/100 g dried sample; p-coumaric
acid: 1422.10 – 1559.96 mg/100 g dried sample). As for betalain pigment, superheated steam drying caused its degradation
but the impact was reduced after combination with ultrasonic-assisted extraction (betanin : 9.77 mg/100 g dried sample;
betaxanthin: 9.07 mg/100 g dried sample). The present result showed that superheated steam drying enhanced the extraction
yield, antioxidant capacity and concentration of phenolic compounds of Alternanthera sessilis red, regardless of the
extraction method.
