Three New Hemiterpene Glycosides from Ilex macropoda.

Chemical and Pharmaceutical Bulletin, 1997
Phytochemical studies of Ilex macropoda led to the isolation of three new hemiterpene glycosides, 4-β-D-glucopyranosyloxy-5-hydroxyprenyl caffeate (aohada-glycoside A), 5-caffeoyloxy-4-β-D-glucopyranosyloxyprenyl alcohol (aohada-glycoside B), 4-(6-O-caffeoyl-β-D-glucopyranosyloxy)-5-hydroxyprenyl caffeate (aohada-glycoside C), together with betulin ...

A new hemiterpene glycoside from the ripe tomatoes

Natural Product Research, 2014
A new hemiterpene glycoside (1) was isolated from ripe tomatoes (the fruit of Lycopersicon esculentum, Solanaceae) along with eight known compounds. The chemical structure of 1 was determined to be 2-methylbutan-1-ol β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranoside, based on spectroscopic data as well as chemical evidence.

Snow Gum Dieback Enhances Trunk Monoterpene Emissions in the Australian Alps

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Canopy decline is increasingly prevalent in high‐elevation snow gum (Eucalyptus pauciflora) forests across the Australian Alps. This phenomenon, known as snow gum dieback, is associated with infestations by the wood‐boring beetle, Phoracantha mastersi.
