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.

A number of exometabolites have been isolated from the deuteromycetePyricularia oryzae Cav., of which harman and O-demethyldiaporthin have been isolated from this species for the first time. The latter is the first example of a hexaketide from fungi of the genusPyricularia, for which only penta- and heptaketides have previously been described.All-Union Scientific-Research Institute of Phytopathology, Moscow.

The alkaloid compositions of four species of plants of the genusArgemone (A. mexicana L.,A. alba L.,A. platyceras Link et Otto., andA. hybrida) collected in the flowering phase in the Tashkent Botanical Garden have been studied. They have yielded 16 alkaloids. Corydine and isocorydine have been detected in plants of this genus for the first time, and O-methyl-platycerine has been found in nature for the first time.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
