Triunia erythrocarpa was identified as containing alkaloids during chemical screening of Queensland Proteaceae using Dragendorff's reagent. A new tropane, 10-hydroxydarlingine (1), and the known tropane, darlingine (2), were isolated from the leaves of T. erythrocarpa. The absolute stereochemistry of 10-hydroxydarlingine (1) was assigned using the advanced Mosher method. T. erythrocarpa is only the seventh member of the Proteaceae to have been shown to produce alkaloids. 
Tropane alkaloids from the Australian plant Triunia montana (Proteaceae)
Four tropane alkaloids, including a new compound triuniamine A (3) a known compound 2,3-dihydrodarlingine (4) with previously unassigned relative configuration and two known compounds darlingine (1),
Increasing the pace of new discoveries in Tropane alkaloid biosynthesis
Molecular techniques are providing an ever-increasing amount of information on the nature and evolution of TA biosynthesis pathways and are aiding the development of techniques for increasing the production of useful tropanes through metabolic engineering.
Cytotoxic turrianes of Kermadecia elliptica from the New Caledonian rainforest.
A LC/APCI-MS study performed on kermadecins A, B and C provided a reliable method for the detection of other analogues existing in small quantities in the extract, which led to the isolation of five other members of this chemical series.
A cyclic dipeptide from the Chilean hazelnut cotyledons (Gevuina avellana Mol., Proteaceae)
This work describes the isolation and full characterization of a cyclic dipeptide cyclo(Arg-Trp) and other compounds from the phenolic enriched extracts of the G. avellana cotyledons and adds evidence on the possible beneficial effects of this nut in human health.
The final steps of cocaine biosynthesis in the Erythroxylaceae provide insight into the biochemistry, physiology and evolution of tropane alkaloid biosynthesis
The current state of tropane alkaloid biosynthesis in plants, their occurrence in the angiosperms and their ecological functions are reviewed and the importance of biochemical investigations of plant secondary metabolite pathways is reviewed in the context of metabolic engineering.
Chirality and Numbering of Substituted Tropane Alkaloids
1H-NMR anisochrony induced by the Mosher’s chiral auxiliary reagents is used, to determine the absolute configuration of (3R,6R)-3α-hydroxy-6β-senecioyloxytropane, a disubstituted tropane alkaloid isolated from the aerial parts of Schizanthus grahamii (Solanaceae).
Chapter 2 Calystegines
Biochemical activities and therapeutic applications for this class of natural compounds are reviewed and calystegines, like other monosaccharide-mimicking alkaloids, inhibit glycosidases due to their similarity to the pyranose moieties of the natural substrates.
Leaf histochemistry analysis of four medicinal species from Cerrado
The objective was to evaluate the histochemistry of the leaf blade of Byrsonima verbascifolia, a species that has been reported as producers of secondary metabolites for pharmacological use, to find leaf regions which produced chemical compounds.
Natural product libraries: assembly, maintenance, and screening.
This review discusses successful strategies and potential pitfalls to assembling a natural product-based library suitable for high-throughput screening and the logistics of moving from an assay hit to pure bioactive compound are discussed.
