The terpenes, sterols, alkaloid (glaucine) and a-tocopherol show seasonal variation for Croton hemiargyreus hemiargyreus and Croton echinocarpus. The amounts of triterpenes are higher during the tropical summer and in most samples the major sesquiterpene was characterized as caryophyllene. The seasonal variation of glaucine showed a maximum be­ tween June and October for C. hemiargyreus, and was present only in January and June in C. echinocarpus.
