Chemistry of the podocarpaceae—XIV
Tetrahedron, 1967Abstract The per-acid oxidation of some phenols and their methyl ethers in the podocarpa-8,11,13-triene series has given both p -benzoquinones and 4-hydroxycyclohexa-2,5-dienones. When reaction mixtures were heterogenous, oxidation also occurred at a Me group remote from the phenolic ring.

Chemistry of the podocarpaceae—VIII
Tetrahedron, 1963Abstract Macrophyllic acid from the heartwood of Podocarpus macrophyllus has been shown to be the bisditerpenoid dicarboxylic acid (I, R H) related to podototarin, and its di-O-methyl dimethyl ester synthesized from 16-hydroxytotarol. Podototarin (IV, R CH3) has been prepared by a one-step enzymatic coupling of (+)-totarol and the coupling ...

Chemistry of the podocarpaceae—IV
Tetrahedron, 1959Abstract The extractives of the heartwood of Podocarpus dacrydioides A. Rich. contain the known diterpenoid constituents, podocarpic acid (I, R = H), methyl podocarpate (I, R = CH3), ferruginol (II), Δ9-dehydro-ferruginol (III), sugiol (9-ketoferruginol, IV), xanthoperol (V) (in trace amount) and a new resin acid, C20H28O5, for which the name ...

Chemistry of the podocarpaceae—VI
Tetrahedron, 1962Abstract Totarol (I, R = H), 16-hydroxytotarol (I, R = OH), sugiol (II), podocarpic acid (III, R = H), methyl podocarpate (III, R = CH 3 ), pododacric acid, β-sitosterol, and two unidentified compounds, the major one of which has been named podototarin, have been isolated from the heart-wood of Podocarpus totara .

Cuticle Micromorphology of Falcatifolium de Laubenfels (Podocarpaceae)
International Journal of Plant Sciences, 1992Cuticle micromorphology of leaves from all five species of the Southern Hemisphere conifer genus Falcatifolium de Laubenfels (Podocarpaceaew) as studied with scanninge lectron microscopy. Both herbarium and preserved specimens were examined and showed no differences in micromorphology.
