“…In accordance with our results, it has been reported that oleanolic acid (3) have toxic effect against Spodoptera frugiperda JE Smith, Spodoptera littoralis, Leptinotersa decemlineata, Myzus persicae and Bemisia tuberculata [56,58,59]. On the other hand, Pungitore et al (2005) indicated that oleanolic acid (2) isolated from Junellia aspera exhibited less toxicity against Sitophilus oryzae (L.) [54]. According to our results, this compound showed weak toxic effect with 36.7-48.3% mortality after 72h of treatment against S. granarius (Table 3).…”

“…According to our results, this compound showed weak toxic effect with 36.7-48.3% mortality after 72h of treatment against S. granarius (Table 3). It has been also reported the high toxic effect of maslinic acid (3) against Sitophilus oryzae (L.) [54]. Likewise, maslinic acid (3) exhibited the highest insecticidal activity against S. granarius, T. confusum and A. obtectus with the lowest LC 50 values of 0.66, 0.61 and 1.71 mg/Petri dish, respectively (Table 6) among the tested substances.…”

“…However, there have been some reports on insecticidal properties of the leaf extracts and its pure metabolites against various insects species [53][54][55][56][57][58][59][60]. Zia et al (2011) tested the extract of olive leaves against chickpea beetle, Callosobruchus chinensis and they found it active against the beetle [57].…”

Olea europea L. emerged as a good source of traditional medicine for the treatment of various ailments of various countries of the world, in particular Mediterranean countries. In this study, oleuropein (1), oleanolic acid (2), maslinic acid (3), a mixture of erythrodiol and uvaol (4 and 5) isolated from the leaves of olive were added at two concentrations (1g/100g feed and 4g/100 g feed) into fish feed. Oreochromis niloticus (Nile tilapia) were fed twice a day with the feed during 96 hours. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) enzymes and glucose levels in the serums of fishes fed with pure compounds were found to be higher as compared with the control group. Pure metabolites affect the liver metabolism of Nile tilapia. These results suggested that the compounds tested affect the liver metabolism of Nile tilapia. Compounds 1, 2, 3 and 4+5 (2.5, 5.0 and 7.5 mg/Petri dish concentrations) were also tested for contact toxic effects against three important stored pests, Sitophilus granarius (weevil), Tribolium confusum (confused flour beetle) and Acanthoscelides obtectus (bean weevil). The toxic effects of the metabolites were lower than those of the insecticide, dichlorvos (DDVP). DDVP caused complete mortality of the insects after 48 hours of treatments, the metabolites caused the mortality rates T. confusum and A. obtectus, respectively. Maslinic acid (3) has the most toxic compound with the lowest LC 50 values (0.66 mg/Petri, 0.61 mg/Petri and 1.71 mg/Petri for S. granarius, T. confusum and A. obtectus, respectively). These results show that maslinic acid (3) as well as other substances can be used as natural insecticides against these pests.

“…Oleanolic acid (13) was previously isolated from Lippia triphylla by Ono et al (2008), while oleanonic acid (12) had not been isolated in the Lippia genus. Both 12 and 13 showed insecticidal activity against Sitophilus oryzae (L.) (Pungitore, García, Gianello, Sosa, & Tonn, 2005) and toxicity towards M. tuberculosis H37Rv (Caldwell, Franzblau, Suarez, & Timmermann, 2000). Compounds 14-19 have not been reported previously in the Verbenaceae family.…”

a b s t r a c tThe Lippia genus is used in ethnobotany as food, beverages, seasoning and antiseptic remedies, among others. The chemical compositions of fifteen extracts of six Lippia species were investigated comparatively by HPLC-PDA. To avoid data replication of previous works on this genus, Lippia lupulina Cham. root ethanol extract was selected for isolation procedures based on Principal Component Analyses (PCA) of such data. Seven compounds previously unreported in this genus were isolated from this extract (a triterpene, two furanonaphtoquinones, a furanochromone, an isoflavone, a stilbene and an iridoid). The activities of extracts, fractions and pure compounds towards Candida albicans, Candida krusei, Candida parapsilosis and Cryptococcus neoformans were investigated. Two fractions from the extract of Lippia salviaefolia leaves showed marked inhibition of fungal growth, in addition to verbascoside and asebogenin, which showed MICs lower than 15.6 lg/ml and may be promising leads for the development of new antifungal agents, especially against C. neoformans.

“…Pentaciclic triterpenes have great potential in the development of agricultural. These compounds show insecticidal and antifeedant activities, especially those with skeletons of ursan, olenan, and lupan types (Pungitore et al, 2005;Omar et al, 2007;McLean et al, 2009). The isolation of triterpenes from Asteraceae extracts can provide structures with insecticidal activity.…”

Asteraceae weeds are rich in chemicals that have biological and pharmaceutical activities. The aims of this work were to describe the phytochemistry and quantify the polyphenols in ethanol extracts from leaves of 12 species of Asteraceae weeds collected in Diamantina, Minas Gerais State, Brazil. The screening of Asteraceae extracts revealed the presence of tannins, steroids, triterpenes, anthocyanins, and flavonoids. The total phenolic content was high in extracts of Lychnophora ericoides (147.97 ± 2.66), Lepidaploa lilacina (141.11 ± 1.99), and Eremanthus elaeagnus (134.61 ± 7.81) and low in extracts of Lychnophora ramosissima (32.65 ± 0.70), and Lychnophora sp. (54.03 ± 0.73). Extracts of Asteraceae weeds from Diamantina could have potential for biological studies that are searching for new pesticides and drugs.
