Baccharis spicata is a dioecious shrub native to the south of South America, and is used as an adulterant of medicinal species of the genus. An analysis of the seasonal variation of total phenols and hydroxycinnamic derivatives was performed in a wild population from an ecological reserve in the city of Buenos Aires, Argentina, in order to know the best moment to collect material for therapeutic purposes. Besides, the ambient temperatures were registered in a range of 5 days before and after the samples were collected. In order to known the statistical significance of the differences, statistical analyses were made. The higher contents of these metabolites were registered in spring and autumn; these seasons had mild ambient temperatures.
