TL;DR: From the aerial parts of Eriostemon tomentellus five coumarins have been isolated as mentioned in this paper, which have been characterized as ostruthin (6-geranyl-7-hydroxycoumarin (1)) and the novel compounds, 8geranyl, 7-hydroxyphenyl-7hydroxymethyl octa-2,7-dienyl)-7-drug-coupmarin(2), and 6-hydroperoxy-3,7dimethyl-decomposition-dimethylocta-
Abstract: From the aerial parts of Eriostemon tomentellus five coumarins have been isolated. These have been characterized as ostruthin (6-geranyl-7-hydroxycoumarin (1)) and the novel compounds, 8-geranyl-7-hydroxycoumarin (2), (E)-6-(7-hydroxy-3,7-dimethylocta-2,5-dienyl)- 7-hydroxycoumarin (3), (E)-6-(7-hydroperoxy-3,7-dimethylocta-2,5-dienyl)-7-hydroxycoumarin (4), and 6-(6-hydroxy-3,7-dimethylocta-2,7-dienyl)-7-hydroxycoumarin (5). In addition tembamide (2-{4-methoxyphenyl}-2-hydroxy-N-benzoylethylamine (6 ) was isolated and the l3C NMR spectrum reported for the first time.

TL;DR: An examination of the aerial parts of Eriostemon apiculatus has shown it to contain the uncommon pyranocoumarins avicennol, cis -avicENNol, dipetalolactone, avicENNin and cis-avicennin, the last of which appears to be novel.

TL;DR: The isolation of an acid, C20H24O5, from Philotheca hasselli and three Eriostemon spp.
Abstract: The isolation of an acid, C20H24O5, from Philotheca hasselli and three Eriostemon spp. is described. The structure, which contains the benzodipyran skeleton, has been shown to be (I).

TL;DR: The steam-volatile leaf oils of Eriostemon obovalis A. Cunn and Phebalium glandulosum subsp. glandulusum Hook were found to contain methyl p-methoxycinnamate and (+)-2,6-dimethyl oct-7-en-4-one respectively as discussed by the authors.
Abstract: The steam-volatile leaf oils of Eriostemon obovalis A. Cunn. and Phebalium glandulosum subsp. glandulosum Hook. (Rutaceae) contain substantial amounts of methyl p-methoxycinnamate and (+)-2,6-dimethyloct-7-en-4-one respectively. In the course of our survey of the Australian essential-oil-bearing flora, we investigated the volatile oils of Eriostemon obovalis A. Cunn. and Phebalium glandulosum subsp. glandulosum Hook. foliage. Both species belong to the family Rutaceae, tribe Boroniae, subtribe Eriostemoninae. Eriostemon obovalis is a small white flowering shrub growing to a height of about 1 m on exposed sandstone clifftops in the Blue Mountains of New South Wales.' Steam distillation of dried leaf material collected at Walls Lookout in the Blue Mountains National Park yielded a volatile oil which deposited on standing white plates shown by spectral evidence and synthesis to be methylp-methoxycinnamate (1). To our knowledge this is the first occurrence of (1) in an essential oil, although it has been isolated as a fungal metabolite2 and as an artefact from the methanol extraction of a plant rich in p-methoxycinnamic acid (2).3

TL;DR: The structure of Eriostemon tomentellus contains an acid, eriostemoic acid, whose structure has been shown to be (II) as discussed by the authors, and the same acid has been isolated from E. thryptomenoides.
Abstract: Eriostemon tomentellus contains an acid, eriostemoic acid whose structure has been shown to be (II). The same acid has been isolated from Geleznowia verrucosa and E. thryptomenoides. Evidence is presented for intramolecular charge-transfer complexes in eriostyl and eriostemyl 3,5-dinitrobenzoates. The structure of franklinone has been confirmed by a synthesis of tetrahydro-franklinone.
