Comparison of Acylated Plant Pigments: Light-resistance and Radical-scavenging Ability

The acylated plant pigments synthesized by lipase-catalyzed transesterification with aromatic acids were compared in respect of their light-resistance and radical-scavenging ability. With both the flavonols and anthocyanins, their acylated derivatives were more stable against illumination with fluorescent light than their non-acylated glucosides. Their radical-scavenging ability partially decreased or was retained by acylation to the glucoside molecules.

Summer Cattle Transhumance and Wild Edible Plant Gathering in a Mapuche Community of Northwestern Patagonia

Cattle transhumance has been practiced since colonial times in Mapuche communities of northwestern Patagonia, which travelled seasonally along the Andean valleys from arid lands towards temperate forests. In this study, we analyzed how this migratory practice affects the abundance and variety of wild edible plants utilized by the Mapuche community of Paineo. Patterns of use for those who practice transhumance were compared with those who do not utilizing ecological variables. Gender and age were also evaluated. The Paineo people collect wild plants in 3 different gathering sites: the A. araucana forest, the Travesía, and their dwelling surroundings. However, those who practice summer transhumance utilize a more diverse variety and a tan greater quantity of wild edible forest plants than those who do not. Moreover, the nutritional value of plants collected by transhumants is greater than those used by non-transhumants. Men practice summer cattle transhumance in a greater proportion than do women and consume significantly more wild edible plants. In contrast, plants from their dwellings and from the Travesía are used in a similar way by both sexes. It was observed that the elderly do not presently participate in transhumance. Our results illustrate a change in wild plant knowledge influenced by the transformation of the summer transhumance pattern.

Edible Wild Plant Use in a Mapuche Community of Northwestern Patagonia

Mapuche Indians have a long tradition of using edible wild resources. The people of Rams (Neuquén, Argentina) consider themselves descendants of the Pehuenches, an Indian group that once inhabited the Pehuén forest region. They now live in the steppe, far away from the forest. Our primary interests are how this community uses edible resources and in analyzing which plants are still utilized. We conducted an ethnobotanical study, which consisted in interviewing several Mapuche families and collecting plants with their help. Ecological variables of plant use, such as search cost, handling time, and nutritional content, were analyzed from the perspective of Optimal Foraging Theory. Our results indicate that the Rams inhabitants have a thorough understanding of their environment, expressed in a selective gathering of wild resources. Cost and benefit trade-offs seem to be considered when edible plants are collected.
