A new compound and five known compounds were isolated from the ethanolic extract of the leaves of Ilex pernyi Franch. Their structures were established on the basis of spectral analysis and identified as trans-isoeugenyl-alpha-L-arabinopynosyl (1 --> 6) -beta-D-glucopyranoside (1) , kaempferol-3-O-sambubioside (2), quercetin-3-O-sambubioside (3), isoquercitrin (4), (+) -syringaresinol-O-beta-D-glucopyranoside (5), amarantholidoside IV (6). Among them, compound 1 is a new phenolic glycoside, named as ilexperphenoside A, and compounds 2-6 were isolated from this plant for the first time.

The mini-cutting physiological condition is vital for the rooting process. For accurate interpretation, considering all mini-cutting responses in an experiment is necessary to identify significant rooting-biomarkers. The study investigates rooting-biomarkers during vegetative propagation, focusing on Ilex paraguariensis (yerba mate) clones of contrasting mini-cutting rooting performance as a case study (i.

This study investigated the valorization of leaves by producing a low-caffeine, antioxidant-rich product through the supercritical antisolvent extraction (SAE) process. The objective was to concentrate the antioxidants while selectively reducing the caffeine. The SAE treatments were conducted using an ethanolic extract of guayusa leaves under varying pressure (80 bar-150 bar) and temperature (35-45 °C) conditions to improve the recovery of chlorogenic acid (CGA) and caffeine fractionation.
