摘要

马奎（Aristotelia chilensis（Mol.）Stuntz）抗氧化剂含量高，最近促使人们对该物种的研究增加。本研究以总酚含量（TP）和比叶面积（SLA）为指标，评估了智利库里科省马奎叶中酚类抗氧化剂根据地理位置和阳光照射的变化。从该省的自然种群中采集树叶，每个地理位置采样15片树叶和3个重复。在全省20个地点评估了SLA与TP、SLA与地理位置、TP含量与地理位置之间的关系。TP变化范围为118.36至201.9 mg∙g-1（GAE），SLA变化范围为76.8至188.2 cm2∙g-1.总体而言，朝北植物表现出最高的TP和最低的SLA。当根据暴露量（朝北、朝南和山谷）对采样种群进行分组时，只有朝北的点与经度呈显著负相关（r=-0.980，P≤0.05），这表明向西移动会发现更少的苯酚含量。TP和SLA因暴露和地理位置而异。相关分析显示，SLA与TP呈显著负相关（r=-0.56，P≤0.05），表明该参数可作为马奎酚类抗氧化剂的实用指标。

Geographic variation in total phenol content and specific leaf area, as antioxidant indicators, of maqui in central Chile

The high content of antioxidants of maqui (Aristotelia chilensis (Mol.) Stuntz) has recently motivated an increase in the research on this species. This study evaluates the variation in phenolic antioxidants of maqui leaves in the Chilean province of Curicó according to geographical location and sun exposure, using total phenol content (TP) and specific leaf area (SLA) as indicators. Leaves were collected from natural populations inside the province, sampling 15 leaves and three replicates per geographic location. The relationships between SLA and TP, SLA and geographical location, and TP content and geographical location, were assessed in 20 locations within the province. TP varied from 118.36 to 201.9 mg∙g-1 (GAE) and SLA from 76.8 to 188.2 cm2∙g-1. In general, north facing plants exhibited the highest TP and the lowest SLA. When grouping sampled populations according exposure (north facing, south facing and valley), only north facing points resulted in a significant negative correlation with longitude (r= -0.980, P≤0.05), implicating that moving westward less phenol content would be found. TP and SLA varied according to exposure and geographical location. Correlation analysis revealed a significant negative relationship between SLA and TP (r = -0.56, P≤0.05), suggesting the use of this parameter as practical indicator of phenolic antioxidants in maqui.

期刊介绍： Bioagro es una revista científica del Decanato de Agronomía de la Universidad Centroccidental “Lisandro Alvarado” (UCLA). Su periodicidad es cuatrimestral y se publica en los meses de enero, mayo y septiembre. Cada trabajo es revisado por al menos dos especialistas en el área, externos a la revista, de cuya opinión depende la aceptación definitiva. Se utiliza sistema de arbitraje doble ciego. La revista va dirigida, fundamental pero no exclusivamente, a profesionales y técnicos del área agrícola. Su objetivo es publicar trabajos científicos originales e inéditos en ciencias agrícolas que enfoquen aspectos de agronomía, botánica y propagación de plantas, entomología y zoología, suelos, fitopatología y protección vegetal, ingeniería agrícola, genética y mejoramiento de plantas, ecología, procesamiento de productos agrícolas, biotecnología y sociales. También pueden ser publicados artículos cortos en los que se presenten descubrimientos científicos, desarrollos tecnológicos y resultados de diagnósticos integrales, en la modalidad de Notas Técnicas. En Venezuela, se encuentra en las bibliotecas de todas las universidades e institutos de educación superior que ofrecen carreras agronómicas, así como de los entes oficiales de investigación agropecuaria. En el exterior, la revista llega a universidades y/o institutos de investigación agrícolas de todos los países de América Latina así como Estados Unidos, Canadá y España.
