“…It was identified as 23-hydroxyursolic acid, which was already found in the root wood of Guettarda angelica, 8 in the cultured cells from Eucalyptus perriniana 9 and also described after hydrolysis of the saponins obtained from the leaves of Ilex integra. 10 Compound 4 exhibited a pseudomolecular ion [M + Na] + at m/z 643 in the FABMS, which suggested the molecular formula C 35 H 56 O 9 . The DEPT subspectra of the 13 C experiments revealed the presence of six methyl, eleven methylene and ten methyne carbons.…”

Dos frutos deIlex paraguariensis foram isolados um novo glicosídeo triterpenóide, o ácido rotúndico 3β-O-α-L-arabinopiranosídeo, denominado matesídeo (4), os triterpenos ácido ursólico (1), ácido acetilursólico (2), ácido 23-hidroxi-ursólico (3) e as saponinas ziyu-glicosídeo I (5) e ilexosídeo II (6). As estruturas foram estabelecidas com base em métodos espectroscópicos, principalmente RMN mono-e bidimensional. Os valores de amargor foram determinados para matesídeo e ilexosídeo II e comparados com os valores obtidos para as saponinas de I. paraguariensis e outras espécies de Ilex. O elevado amargor encontrado para o ilexosídeo II, uma das saponinas majoritárias presentes nos frutos e não encontrada nas folhas de I. paraguariensis, sugere que o uso dos frutos alteraria de maneira significativa o sabor do produto erva-mate e também poderia produzir efeitos fisiológicos ainda não conhecidos.A new triterpenoid glycoside, 3β-O-α-L-arabinopyranosyl rotundic acid, named here mateside (4), and the known triterpenes ursolic acid (1), acetylursolic acid (2), 23-hydroxyursolic acid (3), the saponins ziyu-glycoside I (5) and ilexoside II (6), were isolated from fruits of Ilex paraguariensis. Their structures were established on the basis of 1D and 2D NMR spectroscopic methods. The threshold bitterness values for mateside and ilexoside II were also determined and compared with saponins obtained from leaves of I. paraguariensis and other Ilex species. The high bitterness of Ilexoside II, one of the main saponins found the fruits, but not in the leaves of I. paraguariensis, suggests that the utilization of the fruits in the Maté production can produce a strong taste variation and unknown physiological effects.

Yerba Mate tea, an infusion made from the leaves of the tree Ilex paraguariensis, is a widely consumed nonalcoholic beverage in South America which is gaining rapid introduction into the world market, either as tea itself or as ingredient in formulated foods or dietary supplements. The indigenous people have used it for centuries as a social and medicinal beverage. Yerba Mate has been shown to be hypocholesterolemic, hepatoprotective, central nervous system stimulant, diuretic, and to benefit the cardiovascular system. It has also been suggested for obesity management. Yerba Mate protects DNA from oxidation and in vitro low-density lipoprotein lipoperoxidation and has a high antioxidant capacity. It has also been reported that Yerba Mate tea is associated to both the prevention and the cause of some types of cancers. Yerba Mate has gained public attention outside of South America, namely the United States and Europe, and research on this tea has been expanding. This review presents the usage, chemistry, biological activities, health effects, and some technological considerations for processing of Yerba Mate tea. Furthermore, it assesses in a concise and comprehensive way the potential of Ilex paraguariensis as a source of biological compounds for the nutraceutical industry.

“…Its bark was used as birdlime to catch a bird in Japan (Divers and Kawakita 1888) because it secretes sticky materials on leaves and stems. In addition, several chemical analyses of I. integra has been conducted, presenting many triterpenoid saponins from leaves (Yano et al 1993), triterpenes showing antifungal effects from fruits (Haraguchi et al 1999), fatty acids from seeds (Hirose et al 1971), and carboxyl acids from leaves and stems (Tori et al 2003), which are similar to I. cornuta (Liao et al 2013).…”

Ilex integra Thunb. is an ornamental tree distributed in Korea, Taiwan, mid-Southern China, and Japan. To understand the genetic differences between I. integra and I. cornuta, we presented complete chloroplast genome of I. integra, which is 157,548 bp long and has four subregions: 86,935 bp of large single copy (LSC) and 18,426 bp of small single copy (SSC) regions are separated by 26,093 bp of inverted repeat (IR) regions including 131 genes (86 protein-coding genes, 8 rRNAs, and 37 tRNAs). The overall GC content of the chloroplast genome is 37.6% and those in the LSC, SSC, and IR regions are 35.7%, 31.9%, and 42.9%, respectively. Phylogenetic trees show that I. integra is clustered with I. cornuta and I. latifolia. Sequence variations identified from I. integra and I. corunta presents that both species have enough sequence variations as different species.
