Abstract

The ethyl acetate extract of the culture filtrate of Phlebia tremellosa promoted elongation of the lateral roots of lettuce seedlings at 250 µg/mL. We purified two compounds that promote root elongation by using activity-guided chromatographic fractionation. On the basis of spectroscopic analyses, these compounds were identified to be isolactarane sesquiterpenes derived from the dehydrogenation of merulactone, which was previously isolated from the same species. We named the purified compounds phlelactones A and B. Phlelactones A and B promoted primary root elongation at 100–300 and 10–30 µg/mL and the elongation and formation of lateral roots at 300–1000 and 30–100 µg/mL, respectively.
