Aiming to contribute to the development of alternative control methods of the coffee leaf miner, Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae), a search for plants able to produce active substances against this insect was carried out, with species collected during different periods of time in the Alto Rio Grande region, (Lavras, Minas Gerais, Brazil). Coff...

This study reports, for the first time, chemical composition and biological activity of essential oil from Brazilian Cymbopogon densiflorus flowers. Thirty compounds were identified by gas chromatography coupled with mass spectrometry (GC/MS), corresponding to 95 % total an chromatogram obtained chromatography-flame ionization detection (GC-FID ). The was mainly composed cis-p-mentha-1(7),8-die...

Spices and herbs have been used for many years by different cultures. The aim of the present study is (1) to investigate in-vitro antimicrobial effects of different spices and herbs (5 species: Rosmarinus officinalis (Rosemary), Coriandrum sativum (coriander), Micromeria fruticosa (L.) Druce subsp. Brachycalyx P.H. Davis (White micromeria), Cumium cyminum (cumin), Mentha piperita (Peppermint) a...

The aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five Mentha species [M. longifolia (L.) Huds., M. piperita L., M. pulegium L., M. rotundifolia (L.) Huds., and M. spicata L.]. The antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

AIM To compare the antibacterial effect of hydro alcoholic extract of Salvia officinalis, Pimpinella anisum, Satureja hortensis, Rhus coriaria, Carum copticum, Mentha longifolia, Achillea millefolium against Streptococcus mutans, Lactobacillus rhamnosus and Actinomyces viscosus through two in vitro methods. METHODS In this experimental study, hydro-alcoholic extracts have been prepared from t...

A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield ...

In this article we discuss the importance of food plants, both introduced and native, in the pharmacopoeia of the Polish community in Misiones, Argentina. Food species constitute a relevant portion of all botanicals used by Polish settlers in home therapies (41%), while introduced food species prevail among the continued herbal remedies used by the study group. We explain this pattern of use by...

This experiment was aimed to evaluate and compare the effects of adding natural extracts (clove, Mentha thyme) with synthetic BHT on some physiochemical, microbial, sensory characteristics lamb patties stored at 4 Cº for 12 days. Results indicated that there’s a steady rise (P<0.01) in oxidative rancidity, microbial pH increasing time storage. Also, significant reduction TBA, observed treate...
