“…Several clerodane diterpenoids showed antifeeding and insecticide activity (Sosa et al 1994;Enriz et al 2000), therefore an acetone extract of the shoots of S. dugesii have been subjected to different chromatography separation to isolate their antifeeding diterpenoids. Two weak antifeeding diterpenoids; dugesin E (160) and isosalvipuberulin (161) while the two others: tilifodiolide (162) and salviandulin E (163) stimulated the feeding of the larvae of Pseudaletia separata Walker to eat fresh leaves of Vicia faba L. in a choice feeding test (Gang et al 2011).…”

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 diterpenoids and triterpenes are natural products derived from mevalonic acid widely distributed in nature (plants, fungi, insects, and other organisms), and present structural variability and broad spectrum of biological activity. Certain clerodane diterpenoids isolated from the genus Baccharis showed antifeedant and repellent activity against larvae of Tenebrio molitor (Sosa et al 1994). Neo-clerodane diterpenes isolated from acetone extracts of the aerial parts of B. flabellata showed antifeedant activity on Tribolium castaneum (Juan Hikawczuk et al 2006).…”

Repellent and acaricidal effects of botanical extracts on Varroa destructor

et al. 2010

Extracts of indigenous plants from South America have shown a broad spectrum of bioactivities. No-contaminant and natural substances have recently resurged as control treatment options for varroosis in honey bee colonies from Argentina. The aim of this work was to evaluate the biological activity of botanical extracts from Baccharis flabellata and Minthostachys verticillata on Varroa destructor and Apis mellifera. The acaricidal and insecticidal activities were assessed by the spraying application method. Both ethanolic extracts showed high levels of toxicity against the mites and were harmless to their host, A. mellifera. During the attractive-repellent test, the olfactory stimulus evoked for the extract from B. flabellata resulted as a repellent for mites. The aromatic stimulus of these extracts would be strong enough to cause disturbance on the behavior of V. destructor. Thus, the repellent effect of these substances plus the toxicity on mites postulate these botanical extracts like promising natural compound to be incorporated for the control of varroosis.
