“…The most active diterpenoids, 149, 150 and 151 inhibited the germination of the seeds of P. rhoeas when applied at concentration of 10-60 mg/ml (Table 4). Moreover, in addition to 149 that was the strongest phytotoxic compound, also 152, 153, and 154 inhibited the seeds of A. sativa from germination, an effect which was comparable to that for pendimethalin, an herbicidal positive control (Bisio et al 2011).…”

“…Dichloromethane extract of the leaves' surface exudates of S. miniata showed antigerminative activity against the seeds of Papaver rhoeas L. and Avena sativa L. which was then subjected to bioassay guided purification. Using different chromatography separations, several bioactive clerodane related diterpenoid were isolated and then identified by IR and different NMR spectral data (Bisio et al 2009b(Bisio et al , 2011.

Bioactive phytochemicals from shoots and roots of Salvia species

The plants of the genus Salvia L. are important medicinal herbs of the Lamiaceae family and some of them such as S. officinalis (sage), S. miltiorrhiza (red sage, Danshen) and S. sclarea (clary sage) have been used as medicinal plants in the folk medicine of several countries. In this review, we discuss the reports that have examined Salvia species with the aim of isolation of pure compounds with different biological activities. The phytochemical analyses of various sage plants have reported 10 monoterpenoids (1-10), 1 sesquiterpenoid (11), 8 labdane (13-20), 15 ent-kaurane (21-35), 82 abietane, rearranged abietane and tanshinone (36-117), 3 icetexane (118-120), 43 clerodane (121-163), and 3 pimarane (164-166) diterpenoids with cytotoxic and antimicrobial, antiprotozoal, antioxidant, phytotoxic and insecticide effects. The other heavier terpenoids, including 3 sesterterpenes (167-169), 10 triterpenoids and b-sitosterol (170-180) have been introduced as minor bioactive compounds in the sage plants. Sahandinone (107), 6,7-dehydroroyleanone, 7-a-acetoxyroyleanone (40), and tanshinone like diterpenoids have been isolated from the roots' extracts of different Salvia species. On the other hand, several radical scavenger phenolic compounds like simple phenolics and caffeic acid derivatives (181-201) including rosmarinic acid, flavonoids (202-217) as well as phenolic diterpenoids, such as carnosol and carnosic acid have been isolated from the aerial parts of these plants. One pyrrole (218) and 3 antimicrobial oxylipins (219-221) are among the other less detected constituents in the members of Salvias. Furthermore, sages also synthesize antifungal, antileishmanial and antimalarial phytochemicals in their roots and shoots, which are reviewed in this paper. We also examine the allelopathic phenomena and the ecologically important phytochemicals identified in different parts of the sage plants. Finally, antifeedant and insecticide phenomena, which are due to the presence of volatile monoterpenes and clerodane diterpenes in these plants, are discussed. Considering the presence of diverse biologically active phytochemicals in the sage plants, they can be suggested as suitable candidates for the formulation of valuable natural medicines.

Clerodane diterpenes: sources, structures, and biological activities

2016

View full text Add to dashboard Cite

The clerodane diterpenoids are a widespread class of secondary metabolites and have been found in several hundreds of plant species from various families and in organisms from other taxonomic groups. These substances have attracted interest in recent years due to their notable biological activities, particularly insect antifeedant properties. In addition, the major active clerodanes of Salvia divinorum can be used as novel opioid receptor probes, allowing greater insight into opioid receptor-mediated phenomena, as well as opening additional areas for chemical investigation. This article provides extensive coverage of naturally occurring clerodane diterpenes discovered from 1990 until 2015, and follows up on the 1992 review by Merritt and Ley in this same journal. The distribution, chemotaxonomic significance, chemical structures, and biological activities of clerodane diterpenes are summarized. In the cases where sufficient information is available, structure activity relationship (SAR) correlations and mode of action of active clerodanes have been presented.
