Abstract:

The aim of this work was to investigate changes in total phenolic, flavonoids and phenolcarboxylic acids (chlorogenic, caffeic, rosmarinic) contents of indigenous sage (Salvia officinalis L.) leaves collected monthly (from May to September) and their correlation with climate conditions. Our results showed that variation in total phenolics amount can be explained by changes in environmental factors (such as temperature and
humidity). The highest content of rosmarinic acid was detected in May (1.0560 g%), July (1.4270 g%) and September (1.3325 g%). Total polyphenols, phenolcarboxylic acids and flavonoids contents showed the same trend, a constant increase being recorded from May to
July (3.2698±0.964 g%, 2.4041±0.0964 g%, 1.4415±0.040 g% for May and 6.3297±0.2042 g%, 5.4916±0.2273 g%, 2.0994±0.0944 g% respectively).
