Pharmaceuticals, 2022 Over the years, labdane diterpenes, norlabdane diterpenes, and bis-labdanic diterpenes with cytotoxic activities have been identified across various families in the plant kingdom including the Zingiberaceae. The present review discusses the distribution of these labdane-type diterpenes within the Zingiberaceae; their extraction, isolation, and ...

Stemarane Diterpenes and Diterpenoids
International Journal of Molecular Sciences, 2019 In this article the scientific activity carried out on stemarane diterpenes and diterpenoids, isolated over the world from various natural sources, was reviewed. The structure elucidation of stemarane diterpenes and diterpenoids was reported, in addition to their biogenesis and biosynthesis.

A Modular Approach for Facile Biosynthesis of Labdane-Related Diterpenes [PDF]
, 2007 Labdane-related diterpenoids are a large group of over 5,000 natural products whose biosynthesis typically proceeds through a labdadienyl/copalyl diphosphate (CPP) intermediate to a further cyclized and/or rearranged hydrocarbon diterpene en route to ...

Diterpenes from Sideritis argyrea
Fitoterapia, 2001 The known ent-kaurene diterpenes 1-9 and a new ent-labdane, ent-6beta,8alpha-dihydroxylabda-13(16),14-diene (10), were isolated from the whole plant of Sideritis argyrea. Their structures were elucidated based on one- and two-dimensional NMR techniques and HRMS.
