Plant Growth Regulation Activity of Column Chromatography Fractions from Mikania micrantha H. B. K. on Raphanus sativus

摘要

Some chemical compounds in low polar fractions of Mikania micrantha H. B. K. extracts can strongly influence seeds germination and seedling growth of Raphanus sativus. In this study, we provide evidence that the chemical compounds in a low polar fraction chromatographed on normal phase silica gel columns from petroleum ether extract of M. micrantha have strong activity to inhibit the seeds germination and seedling growth of Raphanus sativus. Two main chemical constituents, α-Bisabolol and Eudesma-5,11(13)-dien-8,12-olide, in the active fraction were confirmed by GC-MS analysis.
