“…The essential oil of Laurelia sempervirens has shown bactericidal (Montenegro et al, 2012), fungicidal (Bittner et al, 2009), and insecticidal (Bittner et al, 2008) activity. According to Niemeyer and Teillier (2007), Bittner et al (2009), andMontenegro et al (2012), the main chemical component of essential oil of L. sempervirens is safrole, which has exhibited toxic effect as a fumigant against S. zeamais and T. castaneum (Huang et al, 1999;2002) but its activity as a contact insecticide against adult and immature insects, residual and repellent effect and effect on seed germination are not yet documented.…”

The maize weevil Sitophilus zeamais Motschulsky is a worldwide key pest of stored products. Usually contact insecticides or fumigants are used against it, but problems as toxic residues, human intoxications, and resistance have triggered the search for alternative control methods as the use of essential oils. The objective of this research was to assess under laboratory conditions, the insecticidal properties of Laurelia sempervirens (Ruiz & Pav.) Tul. essential oil against S. zeamais. In contact toxicity bioassay assessed treatments were 0 (control), 1.25, 2.5, 5.0, 10, 20, and 40 mL essential oil kg -1 grain and 0 (control), 25, 50, 75, 100, 125, 150, and 175 μL essential oil L -1 air in fumigant toxicity tests. The highest toxicity by contact activity was reached by concentrations higher than 10 mL essential oil kg -1 grain (100% mortality). The same treatments totally inhibit F1. The dose of 175 μL essential oil L -1 air showed a significant toxicity by fumigant activity causing 72.5% of dead insects. The other treatments did not surpass 5% mortality. In offspring effect (F1) bioassay, all treatments had an insect emergence significantly lower than the control but concentrations equal or higher than 10 mL essential oil kg -1 grain prevented the emergence of F1 during the 7 wk of bioassay. The residual effect of contact toxicity remained by 15 d. The treatments based on essential oil lead to a weight grain loss lower than control and germination was not affected. All assessed treatments showed repellent effect. The essential oil of L. sempervirens has promissory perspectives to maize weevil control.

“…Several factors can influence the replication of hepatocytes, with direct or indirect effects on DNA synthesis, which are called mitogenic and co-mitogenic factors, respectively 24,25,28 . As in this study, leaves-derived extracts of Peumus boldus induced hepatocytes proliferation; it is possible to suggest that this natural product display trophic effects on liver tissue.…”

PURPOSE:To assess the effect of aqueous extract of Peumus Boldus (AEPB) on the liver proliferative response after parcial hepatectomy of 70% (PH) in rodents. METHODS:Twenty Wistar rats were divided in two groups: AEPB100 (whose rats received 100mg/Kg of AEPB, once a day, orally, in 4 days prior to the first surgical procedure) and Vehicle (whose rats were treated similarly with distilled water). Both groups underwent PH. After 24 hours the remaining livers were removed for studying the proliferation of hepatocytes by Ki-67 and 2mL of blood were collected for serological assessment: cholesterol, glucose, triglycerides, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total, direct and indirect bilirubin. All data were analyzed by Gaussian distribution. Statistically significant differences between mean values were analyzed using T Student's test. Non-Gaussian data were analyzed using Mann-Whitney's test. RESULTS:The liver of all these rats presented positive staining of Ki-67, indicating liver proliferation. Laboratory results showed no significant difference in serum values between the analyzed groups. The analysis of Ki-67 was significantly more positive in AEPB100 group than in Vehicle group. CONCLUSION:Aqueous extract of Peumus Boldus acute administration exerts significant positive effect on liver regeneration after 24h in rats that underwent parcial hepatectomy, while maintaining unchanged hepatic function.

“…On the other hand, in the food industry, Cladophialophora has been isolated in non-integral maize flour, tomatoes, carrots, apples, strawberries and pears (Badali et al, 2008;Romão-Dumaresq et al, 2016). In addition, taking into account the content of metabolites and the antioxidant capacity presented by G. tinctoria, it is possible to project its biological activity on various microorganisms and to present itself as an alternative to the antagonistic action exerted by extracts from native and endemic Chilean trees such as Laurel (Laurelia sempervirens), Boldo (Peumus boldus) and Tepa (Laureliopsis philippiana) against pathogenic strains of plant species such as Rhizoctonia solani, Pythium irregulare, Ceratocystis pilífera, Phragmidium violaceum and Fusarium oxysporum (Bittner et al, 2009). …”

The endemic Chilean edible plant Gunnera tinctoria (Nalca) is highly appreciated in the south of Chile by the small farmers. Nevertheless, no background exists about his secondary metabolites. In the present study, in the leaf from G. tinctoria was investigated the content of bioactive compounds like coumaric acid, ascorbic acid and total phenols; the antioxidant capacity was evaluated by 3-ethylbenzothiazoline-6-suslfonic acid (ABTS), oxygen radical absorbance capacity (ORAC), ferric reducing antioxidant power), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods reducing sugars were measured. Finally, the biological activity was evaluated against Cladophialophora and Cryptococcus laurentii. The results suggest that the most abundant constituent in the extract were catechin (1344.97 mg/100 g dry weight) and epicatechin (1429.28 mg/100g dry weight), and was confirmed and quantified by high performance liquid chromatografy (HPLC-PDA); while the ORAC methodology showed a high antioxidant capacity (192000.0±5.91 umol Trolox Eq/100 g dry weight). On the other hand, the extract had a fungicide effect against both microorganism assayed, inhibiting the growth of Cladophialophora´s mold-and the yeast Cryptococcus laurentii. This is the first report of antioxidant capacity, bioactive compounds and biological activity of G. tinctoria, and these findings suggest that an extract prepared from the Nalca leaf may be a promising source of antioxidant and bioactive compounds and as a research object by being an antifungal and therapeutic alternative in development.
