Chemistry of the podocarpaceae—VII

Tetrahedron, 1963
Abstract Totarol (I,R  CH3), 16-hydroxytotarol (I,R  CH2OH) 16-oxototarol (I,R  CH:O), sugiol, podocarpic acid, and two unidentified compounds have been isolated from the heartwood of Podocarpus hallii. The structure (II, R  H) of podototarin, found in P. totara but not in P.

Chemistry of the podocarpaceae—XIV

Tetrahedron, 1967
Abstract 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, 1963
Abstract 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, 1959
Abstract 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, 1962
Abstract 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, 1992
Cuticle 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.

Cuticle Micromorphology of Parasitaxus de Laubenfels (Podocarpaceae)

International Journal of Plant Sciences, 1995
Cuticle micromorphology of three collections of the parasitic conifer Parasitaxus ustus (Vieillard) de Laubenfels (Podocarpaceae) was studied with scanning electron microscopy. External and internal cuticle features of abaxial and adaxial leaf surfaces of both vegetative and epimatium-bearing branches are characterized. Leaves are amphistomatic with an

Podocarpaceae

1984
Monoecious or dioecious trees and shrubs, some prostrate (and one parasitic on another member of the family, Parasitaxus, in New Caledonia). Each cotyledon, of which there are usually two but in a few cases more, a fused pair with a corresponding bifid tip.
