Changes in the Total Polyphenolic Content and Antioxidant Capacities of Perilla (Perilla frutescens L.) Plant Extracts during the Growth Cycle

Table 4

Trolox equivalent antioxidant capacity (TEAC) of the perilla extract and fresh matter (FM) at different growth stages.

Growth stage	Plant height	TEAC
	(cm)	(mmol Trolox eq./g extract)	(mmol Trolox eq./g FM)
Early vegetative	15
Medium vegetative	30
Late vegetative	40
Early flowering	60
Full flowering	70

Means with the same letter in the same column are not significantly different ().
