O-acylated lignans from the wood of Abies species

Summary From the wood of the Siberian firAbies sibirica Ledeb. and the Khingan firA. nephrolepis Maxim., five new compounds have been isolated which are ester derivatives of the lignans lariciresinol, olivil, and hydroxymatairesinol.It has been established that olivil is esterified at the primary alcoholic hydroxyl by hydroxycinnamic acids — p-coumaric or ferulic — and lariciresinol is esterified by vanillic acid. A representative of the guaialignanolides — hydroxymatairesinol — is esterified at the secondary aliphatic hydroxy group with p-hydroxybenzoic or vanillic acid.Institute of Organic Chemistry, Siberian Branch of the Academy of Sciences of the USSR.
