Extracts and Fractions from Edible Roots of Sechium edule (Jacq.) Sw. with Antihypertensive Activity
Figure 5
Chromatograms of SeRHA extract (blue line) compared with SeRAcet (black line); they were read at two length waves, panel (a) at 290 nm and panel (b) at 340 nm. Fractions R14 (black line) and R17 (blue line) represented in panels (c) and (d) read at 340 nm and 290 nm, respectively, show two peaks (1 and 2) with retention times of 7.21 and 8.04 min. Peak 2 corresponds to the cinnamic acid methyl ester that corresponds to the MS-PDA-HPLC analysis represented in Figure 6(a) peak 4 and Figure 6(b) peak 160.3.
