Characterization of Powdered Yacon (Smallanthus sonchifolius) Juice and Pulp

Food and Bioprocess Technology, 2011
The present work aimed to study the drying behaviour of a 40oBrix concentrated yacon juice preparation using native corn starch as the encapsulating agent and also the drying of yacon pulp. The experimental trials were carried out in a forced air dryer at temperatures of 50, 60 and 70°C for 5 h.

Two new sesquiterpene lactones from leaves of yacon, Smallanthus sonchifolius

Journal of Asian Natural Products Research, 2017
The chemical constituents of 95% EtOH extract of yacon leaves were separated to yield two new sesquiterpene lactones, together with three known compounds. The two new compounds were characterized to be 8β-angeloyloxy-13-methoxyl-11, 13-dihydromelampolid-14-oic acid methyl ester (1) and 8β-(3-methylbut-2-enoyl) oxy-13-methoxyl-11, 13-dihydromelampolid ...
