Cecropia pachystachya: A Species with Expressive In Vivo Topical Anti-Inflammatory and In Vitro Antioxidant Effects

Table 1

Antioxidant activity determined by DPPH assay, reducing power, 𝛽-carotene/acid linoleic, and TBARS methods.

Species and positive controls	DPPH scavenging activity (IC50---µg/mL)^a	Reducing power (EC50---µg/mL)^a	𝛽-carotene/acid linoleic system (IC50---µg/mL)^a	TBARS (% inhibition)^a
CPM	3.1 (±0.25)*	10.85 (±0.65)*	5.1 (±1.31)*	81 (±0.04)
Quercetin	0.98 (±0.20)	(—)	1.19 (±0.62)	(—)
Rutin	2.10 (±0.60)	(—)	(—)	(—)
Ascorbic acid	(—)^b	1.80 (±0.48)	(—)	(—)
BHT	(—)	(—)	(—)	88 (±0.01)

aValues expressed as mean ± S.D. of triplicates testes.
^bNot determined.
*Statistically different (𝑃<0.005) from positive control group (quercetin and rutin in DPPH test, ascorbic acid in reducing power, and quercetin in 𝛽-carotene/acid linoleic system) (ANOVA followed by test 𝑡-Student).
