Phytochemical Study and In Vitro Biological Activities of Hibiscus panduriformis Burm. f. (Malvaceae), Alternanthera pungens Kunth (Amaranthaceae), and Wissadula rostrata (Schumach.) Hook. f. (Malvaceae)

Table 1

Polyphenol compound contents of the methanol extracts of the three plants.

Polyphenols	Hibiscus panduriformis	Alternanthera pungens	Wissadula rostrata
Phenolics^1	^a	^b	^c
Flavonoids^2	^a	^b	^c
Condensed tannins^3	^a	^b	^b

Values presented are the average of three . ^{1, 2, 3, 4}Expressed in terms of GAE, RuE, CE, and TAE (milligram of gallic acid, rutin, catechin, and tannic acid equivalents per gram of dry extract, respectively). In each row, values bearing different letters ^{(a, b, and c)} are considered highly statistically significant at (two-way ANOVA followed by Tukey’s test).
