Hydroqulnone, arbutln and caffelc acid have been reported to occur In several plant families, but the appearance of hydroqulnone and arbutln In small everlasting represents only the second reported occurrence of these compounds In Composltae. The two compounds have been previously reported In three species of Serratula (Composltae) (19). 

This investigation has shown hydroquinone to be a potent phytotoxin toward developing leafy spurge roots. Hydroquinone, originating from a chronic oversupply of arbutln, is considered to play a significant role in the observed allelopathy of small everlasting toward leafy spurge.

Interestingly, the teachings of Democritus (460-37Ibc) did not become so important, although in the sense of natural science (as we now know it), they were much more relevant. Leucippus was Democritus s teacher, and thus the scholar took over the basic ideas of atomic theory from his teacher atoms as tiny particles, too tiny to be visible, which were everlasting and could not be destroyed. They were supposedly made from the same material, but were of different sizes and weights. According to Democritus, life arises from a process in which the small particles of the moist earth combine with the atoms of fire.
