The leaf essential oils ofPilidiostigma (Myrtaceae)

Abstract

Pilidiostigma glabrum Burret, P. recurvum (C.T. White) A.J. Scott, P. rhytisperma (F. Muell.) Burret, P. tetramerum L.S. Sm., P. tropicum L.S. Sm. and Pilidiostigma sp. (Mt Lewis G.P. Guymer 2024) all gave leaf essential oils composed almost entirely of sesquiterpenes. The principal components of all species were aromadendrene, allo‐aromadendrene, β‐caryophyllene, α‐copaene, viridiflorene, bicyclogermacrene, δ‐ and γ‐cadinene and globulol.

Biologically Active Dibenzofurans from Pilidiostigma glabrum, an Endemic Australian Myrtaceae

“…Five new dibenzofurans (1−5), along with one known such compound (6), were isolated from the leaves of P. glabrum. Compound 1, obtained as light yellow needle-shaped crystals, showed a [M + Na] + peak at m/z 451.1723 (calcd 451.1733) by high-resolution electrospray-ionization time-offlight mass spectrometry, corresponding to a molecular formula of C 24 H 28 O 7 .…”

“…5 The leaf essential oils of five Pilidiostigma species have been characterized and found to consist almost entirely of sesquiterpenes. 6 As part of our work on identifying natural products with potential application in wound healing, we here report six (including five new) biologically active dibenzofurans from Pilidiostigma glabrum Burret, an endemic Australian species commonly known as plum myrtle. This species is a shrub or small tree to 5 m that grows in rainforests and wet sclerophyll forests along Australia's east coast, north from approximately 31°S.…”

Leaf essential oils of the genusLeptospermum (Myrtaceae) in eastern Australia, Part 4.Leptospermum deanei and allies

“…The oils all individually bear resemblance to species already investigated in previous parts of this series. 1,7,15 It appears that, with the exception of some notable species still to be reported on (e.g. L. petersonii, L. liversidgei, L. morrisonii,), the species of Leptospermum of eastern Australia all possess oils which could best be described as either monoterpenic or sesquiterpenic oils.…”
