IC 50 value of the root extract Based on the screening results, it was indicated that the root had the highest scavenging activity which was The scavenging activity of these extracts was lower compared with both antioxidants, BHT The results of the antibacterial screening of the leaves and roots of Leucas aspera were presented in table 2.

Curr Med Chem ;8: DPPH assay was performed to determine the free abtimicrobial scavenging activity of all the concentrations at 1. Antifungal activity of three Chilean plant extracts on Botrytis cinerea. By using a sterilized forcep, three sterilized Whatman paper disks 6 mm in diameter were transferred onto the agar surface.


B, Modi K and Shah M. In recent years, multiple drug resistance in human pathogenic microorganisms has developed due to indiscriminate use of commercial antimicrobial drugs commonly used in treatment of infectious diseases. The entire asera is also used as an insecticide and indicated in traditional medicine for coughs, colds, painful swelling and chronic skin eruption [10]. The results indicate that the root extract possess the highest antioxidant as well as antimicrobial activity.

The difference of the result may be due to the different solvent used for the extraction and also the fact of using whole antimifrobial and part of the plant. The LC 50 value for 12 h and 24 h observation were 2. This was kept for 30 min of incubation in dark by using the dark box.

B Mid ; 4: Support Center Support Center. Suspension containing 15 larvea was added into each test tube and was incubated at room temperature for 12 h under the light.

A sterile swab was used to spread fungal culture evenly over the medium. The leaves are also used as insecticides and mosquito repellent in rural area 6. It has been reported that there is an inverse relationship between antioxidative status and incidence of human diseases such as cancer, aging, neurodegenerative disease, and atherosclerosis [3].

J Nat Prod ; Based on the results, the root extract showed the highest zone of inhibition compared with all the extracts against all the tested microorganisms, followed by the flower extract which was more active against Salmonella species compared with other tested microorganisms.


Antioxidant and antibacterial activity of different parts of Leucas aspera

Conclusions The present finding suggests that the methanol root extract of L. Thanking you Yours truly S. Data from in-vitro antifungal assays obtained from the fourth day after inoculation were subjected to an ANOVA analysis, followed by a pair wise comparison of means Tukey. The extract obtained was filtered using membrane filter paper. The bacteria were subcultured overnight in Muller Hinton broth which was further adjusted to obtain turbidity comparable to McFarland 0.

Biotechnology of medicinal plants-recent advances and potencial.

Preliminary antinociceptive, antioxidant and cytotoxic activities of Leucas aspera root. The percentage of scavenging of all the plant extracts root, flower, leaf and stem was compared with positive controls.

So please consider my corrected paper, demand draft and make the further process. Phytochemical extraction and antimicrobial properties of different medicinal plants:
