“…Cembrane-type diterpenoids are a large and structurally varied group of natural products isolated from both terrestrial and marine organisms. Especially, the Greek tobacco elaborates different types of cembranes many of which contain a γ-lactone group (Connolly and Hill 1991). Interestingly, some liverworts produce highly oxygenated cembranes (Asakawa et al 2013).…”

“…Interestingly, some liverworts produce highly oxygenated cembranes (Asakawa et al 2013). From a biomedical perspective, cytotoxicity is the most remarkable property of this class of diterpenoids, represented by sarcophytol originated from soft coral (Connolly and Hill 1991).…”

“…Podocarpus species biosynthesizes podocarpanes as predominant metabolites. Connolly and Hill (1991) published the encyclopedia of di-, sester-, and triterpenoids in which more than 1000 of the structures of diterpenoids have been presented. Hanson et al (2017) reported the review article which covered the isolation and structure elucidation of terrestrial origin diterpenoids that include abietanes, cembranes, kauranes, labdanes, and their cyclic products including 228 references.…”

A number of foods, vegetables, fruits, and beverages (tea, coffee, and liqueur) contain many kinds of diterpenoids (mainly abietanes, cembranes, clerodanes, cyatanes, dolabellanes, fusicoccanes, kauranes, labdanes, pimaranes, taxanes, trachilobanes, totaranes) and their related compounds. This chapter summarizes the distribution of diterpenoids in dietary foods, vegetables, fruits, beverages, and processed foods, and their biological and pharmacological activity, effects, and application to our health, as well as metabolic pathways of several diterpenoids, which are widely distributed in dietary foods, by microorganisms and mammals.

“…However, studies with species found in other areas of the world indicate protoanemonin concentrations to be low, in the range of 0.02% -0.05% wet weight (Minakata et al 1983;Bonora et al 1985). Plants also contain glycoside derivatives of oleanolic acid terpenoids (Connolly and Hill 1991). Plants also contain glycoside derivatives of oleanolic acid terpenoids (Connolly and Hill 1991).…”

Terpene synthases (TPSs) are pivotal enzymes for the biosynthesis of terpenoids, the largest class of secondary metabolites made by plants and other organisms. To understand the basis of the vast diversification of these enzymes in plants, we investigated Selaginella moellendorffii , a nonseed vascular plant. The genome of this species was found to contain two distinct types of TPS genes. The first type of genes, which was designated as S. moellendorffii TPS genes ( SmTPSs ), consists of 18 members. SmTPSs share common ancestry with typical seed plant TPSs . Selected members of the SmTPSs were shown to encode diterpene synthases. The second type of genes, designated as S. moellendorffii microbial TPS -like genes ( SmMTPSLs ), consists of 48 members. Phylogenetic analysis showed that SmMTPSLs are more closely related to microbial TPSs than other plant TPSs. Selected SmMTPSLs were determined to function as monoterpene and sesquiterpene synthases. Most of the products formed were typical monoterpenes and sesquiterpenes that have been previously shown to be synthesized by classical plant TPS enzymes. Some in vitro products of the characterized SmMTPSLs were detected in the headspace of S. moellendorffii plants treated with the fungal elicitor alamethicin, showing that they are also formed in the intact plant. The presence of two distinct types of TPSs in the genome of S. moellendorffii raises the possibility that the TPSs in other plant species may also have more than one evolutionary origin.
