【 摘 要 】

The chemical seasonal variability of Maytenus aquifolium Mart. (Celastraceae), a Brazilian medicinal plant known as "espinheira santa", was investigated on specimens cultivated at Ribeirão Preto SP, Brazil, at the four seasons of two years. The content of total phenolics, flavonoids and triterpenes varied from 21.96 to 45.92 mg total phenolics (expressed as tanic acid) / g dried leaves, 55.88 - 93.20 mg total triterpenes / g dried leaves, and 1.349 - 3.859 mg flavonoid / g dried leaves. Sample Spring 92 had the higher content of flavonoids and total phenolics, while sample Winter 94 had the highest content of triterpenes.
