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.

GeroScience, 2020 Terpenes and their derivatives have been used conventionally as potential dietary supplements to boost the nutritional value of endless food products. Several plant-based complex terpenoid and their derivatives have been reported for a wide range of medicinal and nutritional properties. However, their simple counterparts, whose production is relatively

Biochemical Characterization and Homology Modeling of Methylbutenol Synthase and Implications for Understanding Hemiterpene Synthase Evolution in Plants [PDF]
Journal of Biological Chemistry, 2011 2-Methyl-3-buten-2-ol (MBO) is a five-carbon alcohol produced and emitted in large quantities by many species of pine native to western North America. MBO is structurally and biosynthetically related to isoprene and can have an important impact on regional atmospheric chemistry.

New Coumarin-Hemiterpene Ether Glucosides and a Structurally Related Phenylpropanoic Acid Derivative from Artemisia Armeniaca [PDF]
Natural Product Communications, 2010 Two new coumarin-hemiterpene ether glucosides, 4’- O-(β-D-glucopyranosyl) desoxylacarol (1), and 5- O-(β-D-glucopyranosyl) lacarol (2), were isolated from the methanolic extract of the aerial parts of Artemisia armeniaca Lam. Their structures were established by means of spectroscopic analysis including 1

New Bitter-Tasting Hemiterpene Glycosides from the Japanese Fern Hymenophyllum barbatum.
Chemical and Pharmaceutical Bulletin, 2001 Hymenosides G--J were newly isolated from the Japanese fern Hymenophyllum barbatum, in addition to hymenosides A--F. The structures of hymenosides were elucidated by extensive two-dimensional nuclear magnetic resonance and/or chemical evidence. The structures of those aglycones were divided into three types, 1,4-dihydroxy-2-hydroxymethyl-but-2-ene, 1,4-
