Abstract: The study was performed on surveys the effect of harvest times on tuber morphological characteristics, tuber yield, anthocyanin content and DPPH scavenging activity of purple sweet potato tubers (Japanese cultivar) was evaluated. The studied site located in Thanh Loi, Binh Tan, Vinh Long and experiment was conducted from September 2014 to March 2015. The harvest times for quality evaluation were from 120 to 176 days after transplanting with 7- day intervals. Results showed that the yield was over 20 tons/ha at 127-day period, and the highest yield was observed at 148-day period with 32.6 tons/ha. The diameter and hardness of tubers increased over the harvest time. The soluble solid contents were fluctuated from 29.3 to 31.8%. The highest anthocyanin contents in tubers were found at 127 days and 141 days after transplanting (>100 mg CGE/100 g dry sample). Anti-oxidant effects of the tuber root extracts reached over 70% at four harvest times from 120 to 141 days after transplanting.
