This result recommended in pharmacopeia monographs for the contradicts the belief that certain plants produce greater plant. The lower percentage of individuals with tubular amounts of active substances when they are subjected to lowers observed in our study signals the importance conditions of stress, in this case a lack of macronutrients of the selection and multiplication of such individuals, and organic material in the plant species calendula.

The with this being an important instrument to maximise the active principle of interest is associated with the secondary production of secondary metabolites which, consequently, metabolism of the plant, which relects speciic adaptations would contribute to improving the inal quality of the to adverse conditions or to defence mechanisms, and such products obtained from calendula.

After 95 days treatments subjected to different treatments. Stationary phase: Mobile phase: Quantitative variation in the chemical constituents The LORG treatment resulted in plants with due to speciic characteristics of the morphological variants greater homogeneity in height than with the other among individuals of a single plant species has been treatments tested, something that would facilitate the previously described in the literature for some medicinal process of mechanisation of lower harvest.

This inding species Silva Junior, In the case of calendula there is is very relevant, since one of the inconvenient aspects of evidence that individuals with orange petals are the richest medicinal cultivars is the lack of standardisation in the in secondary metabolites Silva Junior, In this work size of the individuals, which results in an increase in we observed that those variants with tubular lowers had labour and, consequently, in the cost of the raw materials a higher lavonoid content, as a percentage, than those produced.

Antioxidant activity was analyzed by percentage of radical scavenging using DPPH solution. Antimicrobial activity was evaluated against Gram-positive, Gram-negative pathogenic bacteria and species of Candida using agar diffusion and minimal inhibitory concentration MIC determination methods according to standard methods.

The leaves presented lipids at secretory cavity and phenols, mainly tannins, in nervures and palisade parenchyma. Polar extracts showed flavonoids, tannins and high content of phenols and flavonoids. The extracts showed great antioxidant activity and antimicrobial activity was better against Candida species than against bacteria. Plinia cauliflora, chemical screening, antioxidant activity, antimicrobial activity.

Berg, Myrtus cauliflora Mart. Myrciaria jaboticaba Vell. Plinia cauliflora DC. Kausel is a plant from O. Berg, Myrciaria tenella DC. Berg and Myrciaria the family Myrtaceae, which has one hundred twenty nine trunciflora O.


Berg are scientific synonims of P. Kausel, Myrtaceae, leaves meters of height, which bark scales every year, that has distilled water and used as negative control.

Anatomical simple leaves, with flowers and fruits together the stem, identification was done with 0. This tree occurs, buffer at pH 6.

Identification preferentially, at flood plain and open forests being find at of hydrophilic substances used: The acid for alkaloids. Identification of lipophilic substances bark of P. Sudan red III for total lipids Johansen, , people to treat diarrhoea and skin irritations Lorenzi, Nile Blue sulphate for acid and neutral lipids Cain, Kausel metabolites classes according to Henriques et al. The extracts were concentrated under reduced used to characterized saponins.

For tannins, it was done pressure and lyophilization. One-dimensional TLC Bacterial and fungal strains silica gel analysis of the four extracts was performed in chloroform: The absorbance was measured at nm using Shimadzu UV spectrophotometer Thin transverse sections of the midvein were after 30 min. A standard curve was plotted using different handmade with a stainless steel razor. Some sections were concentrations of an aqueous solution of tannic acid.

Souza-Moreira, Raquel R.

Moreira, Luis V. Sacramento Rosemeire C. Total flavonoids content was determined in sterile well microplates. The wells were filled with by colorimetrical method described by Djeridane et al. The extracts 0.

Final and centrifuged at g for 15 min. The volume of the bacterial inocula were 2. Final yeast inocula were 2. The absorbance was measured at Ampicillin and amphotericin B were used as positive nm after 15 min at room temperature. A standard curve control to bacteria and yeast, respectively.


Bacterial was plotted using different concentrations of rutin solution growth was indicated by addition of 0. The percentage of total flavonoids in the aqueous solution and MIC values were identified as extracts was calculated using a linear equation based on the lowest extract concentration in which no growth is the standard curve. Yeast MIC values were identified in methanol was evaluated by radical scavenging capacity as the lowest extract concentration in which there was no with 0.

Gallic absence of growth to red growth. It was added 2. Blank solutions were done with 1. Anti-radical activity was calculated as discolour percentage of DPPH according to the equation: It was noted that the leaves of Plinia cauliflora DC. It was verified the presence of phenols, conveniently diluted in culture medium. All tests were tannins and alkaloids in midvein and smaller veins; performed according to standard methods and to Ostrosky phenols were also verified in palisade parenchyma.

Lipids et al. Steel templates were placed on the solid medium hydrolysable tannins and flavonoids. In contrary of histochemical reaction, TLC tests did not indicate the presence of alkaloids, which Assay for antimicrobial activity must be investigated. CHCl3 extract showed only a weak blue spot around start point.

Kausel, Myrtaceae, leaves Table 1. Total phenolic and flavonoid content in the extracts of Candida species and C. This work had interesting results against 50 EtOH Candida albicans is the yeast species 70 EtOH H2O Resistance to commonly gallic acid, rutin and vitamin C Figure 1. Choi et al. Plant phenols have potential antioxidant increasing Duarte et al. Other studies Souza et al. Besides, it was possible to was seen in this study since chloroformic extract exhibited indicate that polar extracts of the leaves have biological the smaller phenol content and antioxidant activity.

It should be emphasize zones Table 2 for polar extracts.

H2O extracts and the activity against Candida species showed extracts have showed weak antibacterial activity whereas by them. It was noticed that CHCl3 extract showed small CHCl3 had not any activity at the highest concentration composition of phenolic content, therefore it could explain tested Table 2. The bacteria selected for this study are the smallest antioxidant and antimicrobial activities. These al. Polar extracts showed great activity against leaves by histochemical and phytochemical methods.

Radical scavenging capacity. A gallic acid. B rutin. C vitamin C. D 50 EtOH extract. E 70 EtOH extract. H2O extract. G CHCl3 extract. Antimicrobial activity of P.Lipids et al. Antimicrobial activity of five herbal extracts against multidrug resistant MDR strains of bacteria and fungus of clinical origin.
