Abstract
El objetivo de la investigación fue caracterizar la exudación extraída de la parte
vegetativa de la especie Puya raimondii, debido a su uso medicinal expresado por los
locales. La muestra fue conformada por 15 puyas que pasaron su época de floración y
que presentaron las mejores condiciones de sanidad (sanos) y vigorosidad (altos), estas
se estratificaron en altitud (4000-4050 msnm, 4050-4100 msnm, 4100-4150 msnm) y
época de colecta (Enero–Febrero, Marzo–Abril, Mayo–Junio). Se recolectó la
exudación secretada por la misma puya (secreción natural). Entre las características
físicas y químicas se analizaron rendimiento (g/m2), densidad relativa (g/ml) contenido
de humedad (%), parámetros dasométricos (diámetro, altura), color (determinados por el
colorímetro y la tabla Munsell), índice de acidez, índice de refracción y nivel de
azucares (fructuosa, galactosa, glucosa, lactosa, maltosa y sacarosa). Para el análisis
estadístico se utilizaron el análisis de varianza (ANOVA) y la prueba Chi Cuadrado. Se
encontró que las características físicas y químicas no se encuentran diferenciadas por la
altitud ni la época de colecta, con excepción del color (p=0,029), dado que se apreciaron
colores más oscuros en el periodo mayo-junio (inicio de temporada seca). Además, se
encontró una tendencia creciente del rendimiento con la altitud y con el paso de una
época de lluvia a seca, una tendencia creciente de la densidad relativa con la altitud, una
tendencia creciente del contenido de humedad con el paso de una época de lluvia a seca,
el diámetro presentó una tendencia decreciente con la altitud, pero creciente con el paso
de una época de lluvia a seca, la altura presentó una tendencia creciente con la altitud,
pero decreciente con el paso de una época de lluvia a seca y los niveles de azucares
fueron inferiores a 0,1 g/100g, independientemente de la altitud y de la época de
colecta.
The objective of the research was to characterize the exudation extracted from the vegetative part of the Puya raimondii species, due to its medicinal use expressed by the locals. The sample was made up of 15 Puyas that passed their flowering season and that presented the best conditions of health (healthy) and vigor (high), these were stratified in altitude (4000-4050 masl, 4050-4100 masl, 4100-4150 masl) and collection time (January – February, March – April, May – June). The exudation secreted by the Puya itself (natural secretion) was collected. Among the physical and chemical characteristics, the following were analyzed: yield (g/m2), relative density (g/ml), moisture content (%), dasometric parameters (diameter, height), color (determined by the colorimeter and the Munsell table), acid index, refractive index and sugar level (fructose, galactose, glucose, lactose, maltose and sucrose). For the statistical analysis, the analysis of variance (ANOVA) and the Chi Square test were used. It was found that the physical and chemical characteristics are not differentiated by altitude or collection time, except for color (p=0,029), since darker colors were appreciated in the May-June period (beginning of the dry season). In addition, an increasing trend of yield was found with altitude and with the passage from a rainy to dry season; an increasing trend of relative density with altitude; an increasing trend in moisture content from rainy to dry season; the diameter presented a decreasing trend with altitude; but increasing with the passage of a season from rain to dry; the height presented an increasing trend with the altitude; but decreasing with the passage from a rainy season to a dry season and the sugar levels were lower than 0,1 g/100g, regardless of the altitude and the time of collection.
