Abstract

This study aimed to identify the main groups of secondary compounds from Crambe abyssinica and evaluate the bioactivity of the hexane, ethyl acetate and methanol extracts on the seed germination and seedling development of tomato, wild poinsettia, hairy beggartick and soybean. The phytochemical screening considered the presence or absence of total saponins, triterpenoids, flavonoids, coumarins, tannins, phenols and alkaloids. In the seeds it was evaluated: germination percentage, germination velocity index, average germination time, index of allelopathic effects, shoot and root length and seedlings dry matter. In the phytochemical screening it was observed that each solvent extracted different compounds. Flavonoids were found only in the ethyl acetate extract and saponin only in the methanol extract. A high allelopathic effect of hexane, ethyl acetate and methanolic extracts of crambe on the bio-indicator species tomato was observed. The hexane and ethyl acetate extracts also showed inhibitory effect on the weed hairy beggartick and did not present negative effects on soybean. There is the possibility of isolating the bio-active compounds of crambe and use them as a bio-herbicide to the alternative control of the weed hairy beggartick.
