Enhanced accumulation of flavonolignans in Silybum marianum cultured roots by methyl jasmonate

► Root culture of Silybum marianum was established. ► Elicitation of flavonolignans and pentahydroxyflavanone in the cultured roots was affected by methyl jasmonate. ► Pentahydroxyflavanone was isolated from grown plant roots and its structure was identified by spectroscopic means.
