  • The hexane extract from Nutmeg, the seed of Myristica fragrans significantly inhibited hepatic drug-metabolizing enzyme activity. Through systematic fractionation by $SiO_2$ column and vacuum liquid chromatography monitoring by bioassay, three components, myristicin, (I), licarin-B (II) and dehydrodiisoeugenol (III) were isolated as active principles. Compounds II and III, with a single treatment (200mg/kg, i.p.) showed not only a significant prolongation of hexobarbital-induced sleeping time but also a significant inhibition of aminopyrine N-demethylase and hexobarbital hydroxylase activities in mice. Compounds I and II provoked a sleep episode at a subhypnotic dose of HB, suggesting that they possess CNS-depressant properties.

  • In order to investigate the acidic chlorinated compounds in pulp bleaching spent liquor, the lignin model compounds, coniferyl alcohol(mp $74^{\circ}C$), ${\omega}$-(2-methoxyphenoxy)-acetoguaiacone(mp $93^{\circ}C$) and dehydrodiisoeugenol(mp $133^{\circ}C$), were synthesized and chlorinated by chlorine in glacial acetic acid. From the chlorinated products, the following chlorine-containing aromatic compounds were identified by TLC. In coniferyl alcohol the chlorine-substituted compounds at 4-, 5-and 4,5-position of aromatic nucleus were identified and in ${\beta}$-0-4 type the compounds substituted chlorine for alkyl group and/or hydrogen at land 1,4-position of aromatic nucleus expected to be formed by electrophilic displacement from ${\omega}$-(2-methoxyphenoxy)-acetoguaiacone were not identified but the chlorine-substituted compounds at 4-, 5-, 6- and 5,6-position of aromatic nucleus were identified.
