Quantification of different secondary metabolite groups.

Assays	S. congesta extract samples
	Crude extract	Fraction I	Fraction III
Total phenolic content (mg GAE/g extract)^b	145.0 ± 0.20^a	102.3 ± 0.15^a	46.4 ± 0.08^a
Total saponin content (mg OAE/g extract)^c	55.5 ± 0.87^a	39.6 ± 1.78^a	251.7 ± 0.95^a
Total flavonoid content (mg SE/g extract)^d	158.2 ± 1.07^a	108.5 ± 0.19^a	152.2 ± 0.18^a

The results are determined within the software Prism 7.^a Results were expressed as mean ± SD (n = 3);  < 0.0001% vs. other fractions. ^bGAE: gallic acid equivalent. ^cOE: oleanolic acid equivalent. ^dSE: stachyspinoside equivalent.
