Hemialboside, a hemiterpene glucoside from Lamium album
Phytochemistry, 1995 Abstract Hemialboside, (S)-1- hydroxy-3-methylbut-3-en-2-yl -β- d -glucopyranoside , was isolated from Lamium album and its structure elucidated from 1H and 13CNMR spectral data.

An Artificial Pathway for Isoprenoid Biosynthesis Decoupled from Native Hemiterpene Metabolism [PDF]
ACS Synthetic Biology, 2019 Isoprenoids are constructed in nature using hemiterpene building blocks that are biosynthesized from lengthy enzymatic pathways with little opportunity to deploy precursor-directed biosynthesis. Here, an artificial alcohol-dependent hemiterpene biosynthetic pathway was designed and coupled to several isoprenoid biosynthetic systems, affording lycopene ...

6-Prenyloxy-7-methoxycoumarin, a coumarin-hemiterpene ether from Carduus tenuiflorus
Phytochemistry, 1992 Abstract From the acetone extract of Carduus tenuiflorus , a new coumarin-hemiterpene ether was isolated, which was identified as 6-(3,3-dimethylallyloxy)-7-methoxycoumarin. The synthesis of this coumarin and that of its positional isomer 7-(3,3-dimethylallyloxy)-6-methoxycoumarin were carried out from esculetin.

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.

Naturwissenschaften, 2012 Mealybugs, which include several agricultural pests, are small sap feeders covered with a powdery wax. They exhibit clear sexual dimorphism; males are winged but fragile and short lived, whereas females are windless and less mobile. Thus, sex pheromones emitted by females facilitate copulation and reproduction by serving as a key navigation tool for ...

New hemiterpene and furolactone-type lignan glycosides from Securidaca inappendiculata Hassk
Phytochemistry Letters, 2020 Abstract One new hemiterpene glycoside, securiterpenoside G (1), one new furolactone-type lignan glycoside, (7R,8R,8′S)-glaberide I 4-O-β-D-glucopyranosyl-(1‴→4″)-O-β-D-glucopyranoside (2), along with two known lignan glycosides, (7R,8R,8′S)-glaberide I 4-O-β-D-glucopyranoside (3) and (7S,7′S,8R,8′R)-4,4′-dihydroxy-3,5,3′,5′tetramethoxy-7,9′:7′,9 ...

Coumarin-hemiterpene ethers from Artemisia species
Phytochemistry, 1985 Abstract In addition to a known derivative, five new coumarin-hemiterpene ethers were isolated from the leaves of Artemisia laciniata, A. armeniaca and A. tanacetifolia and identified by 1H NMR and, in part, by 13C NMR spectroscopy. The coumarin patterns are characterized particularly by compounds with a hydroxylated and saturated isoprenoid unit ...
