Notes on economic plants Alkaline substances used with coca (Erythroxylum coca, Erythroxylaceae) leaf insalivation in northwestern Argentina.--In rural areas of the moist forests in the upper Bermejo basin of the Provincia de Salta, Argentina, several plant species are involved in the manufacture of alkaline substances collectively known as yista, which are used in conjunction with the insalivation of coca (Erythroxylum coca) leaves (1, 2).

Abstract

Alkaline substances used with coca (Erythroxylum coca, Erythroxylaceae) leaf insalivation in northwestern Argentina.--In rural areas of the moist forests in the upper Bermejo basin of the Provincia de Salta, Argentina, several plant species are involved in the manufacture of alkaline substances collectively known as yista, which are used in conjunction with the insalivation of coca (Erythroxylum coca) leaves (1, 2). Alkaline substances are primarily responsible for the transformation of alkaloids to free bases thus allowing a better extraction of the plant alkaloids. Little is known of the chemical composition of yista and their buffer capacity (3). In this note we report the composition of yista, including plant salt and preparations with different agglutinants, from the province of Salta. Our work was carried out in the Upper Bermejo Basin (Fig. 1), which is located near the Bolivian border to the north of the province of Salta, in the localities of Lipeo and Baritti, Santa Victoria district (64o45 ' W and 22~ ' S).
