Abstract

The present work to evaluate the phytochemical screening and biological evalution of Daucus carato root and stem extracts. we done screening for antimitotic and antibacterial activities. The extracts of this plant also found applications in many of the traditional medicines. The antibacterial activities were assay of organic extract of Daucus carota root & stem. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were evaluated using standard microbiological techniques. They showed a high significant antibacterial activity using microorganisms such as Bacillus sp., staphylococcus sp. lactobascillus, Xanthomonas. Appreciable quantities of phytochemical such as alkaloids, glycosides, phytobatannins proteins and amino acids.

Introduction

Daucus carota having a scientific name of carrot belongs to family apiaceae and it contains many of chemical constituent. The carrot (Daucus carota subsp. sativus) is a root vegetable, usually orange in colour, but many other were found like purple, black, red, white and yellow varieties exist. Aromatic and medicinal plants, have been widely used in folk medicine to treat several ailments. Which are widely described as having several bioactive properties such as antioxidant, anti-inflammatory, antifungal, antibacterial, hepatoprotective, cardioprotective, anti-hypertensive, antidiabetic, immune enhancer activity, wound healing activity [1-13]. The species Daucus carota commonly known as carrot, is recognized worldwide due roots widely used for both food and medicinal purposes. It is one of the edible root plants and a rich source of anthocyanins, carotenoids (α, β, ? carotene), vitamins A, B and C.

Test for Phytochemicals

Procedure

1

Alkaloids

Dragendroff’s Test

1g of the formulation was extracted with 20 ml alcohol by refluxing for 15 min and filtered and the filtrate was evaporated to dryness. The residue was dissolved in 15 ml of 2N H2SO4 and filtered. Filtrate was made alkaline and extracted with chloroform. The chloroform extract was evaporated to dryness on the water bath. The residue left after evaporation was tested for the presence of alkaloids with dragendroff’s reagent. Formation of orange-coloured precipitates indicates the presence of alkaloids.

2

Carbohydrates

Molisch's Test

To the ethanolic extracts of formulations, α-napthol and concentrated H2SO4 were added. Development of purple colored ring indicates the presence of carbohydrates.

Fehling's Test

To 1 ml of ethanolic extracts of formulations, 1 ml of the Fehling solution (Fehling A + Fchling B) was added. The mixture was heated on boiling water bath for 5-10 min. Development of yellow precipitates, changing to brick red precipitates indicates the presence of reducing sugars.

3

Glycosides

Chrysarobin Test

0.1gm of powder was dissolved in H2SO4, deep red solution is produced indicates the presence of glycosides.

4

Flavonoids

FeCl3 Test

Extract was treated with FeCl3 solution. Formation of green to black color indicates presence of flavonoids.

Shinoda Test

Extract was treated with the mixture containing piece of magnesium ribbonand HCl. Formation of red colour indicates presence of flavonoids.

NaOH Test

To the extract add 10% NaOH was added, Formation of yellow colour indicates presence of flavonoids.

Lead acetate Test

To the extract add 10% Lead acetate solution was added. Formation of yellow colour ppt. indicates presence of flavonoids.

 

Mineral acid Test

To the drug add conc. H2SO4 was added. Formation of orange colour indicates presence of flavonoids.

Zn/Hcl Test

Pinch of zinc dust was added to extract and conc. Hcl was added. Formation of red colour indicates presence of flavonoids.

6

Tannins

Lead acetate Test

To 2-3 ml of aqueous extracts of the formulations, 2 ml of 10 %w/w solution of lead acetate was added. Formation of heavy dull yellowish precipitates indicates the presence of tannins.

7

Proteins

Biuret Test

To 3 ml of extracts of the formulations, add 4% NaOH and few drops of 1% CuSO4, solution. Violet or pink colour appears.

Millon's Test

To 3 ml of extracts of the formulations, add 5ml Millon's reagent. White precipitate is formed. Upon warming, the precipitate turns brick red or the precipitate dissolves giving red coloured solution.

 

MATERIALS AND METHODS:

Collection and identification of plant material:

Daucus carota plant consists root, flowers, stem, etc. The long and short leaves were procured from the backyard of state bank of India, Dallavalasa village ponduru mandal, Srikakulam, Andhra Pradesh state of India.

Preparation of Daucus carota root extract:

Root part was isolated from the Daucus carota and then cut it into small pieces i.e in 2.5cms and make into extract this extract is directly used to carry out the biological activities and phytochemical screening studies.

Phytochemical Screening.

Phytochemical screening of extracts

Following chemical tests were carried out for Daucus carota root extract to identify the presence of various phytochemical constituents. Chemical tests for detection of chemical constituents:

Evaluation of Antimitotic activity of Daucus carota root extract [17]

Green gram seeds were purchased from the market and stored in a moisture free place in self-sealing cover. Then accurately weighed 5grams of seeds and incorporated in each and every sigma-aldrich polystyrene petri dishes to study the antimitotic activity of Daucus carota root extract. In Control only vehicle is used that vehicle is distilled water.After getting the results of antimitotic activity of root extract of daucus carota. we randomly selected 3 seeds from each and every petriplate and calculate the germination length in cms of the seeds and after that we done average length calculation.

From the results of antimitotic activity of Daucus carota root extract we conclude that highest strength of the extract is hot having any seed germination.so this root extract is having potential antimitotic activity.

Evaluation of Anti-microbial activity of Daucus carota root extract [18]

We collect sugarcane stem from the sugarcane field at Dharma puram village, Ponduru mandal, Srikakulam, Andhra Pradesh State. From that we Was cut sugarcane stem it into small pieces these pieces was going to crushed then finally we get a sugarcane solution, from that we filtered it thus we obtained sugarcane filtrate. Immediately after sugarcane is cut, the microflora inside its stem is composed of yeasts and bacteria. Bacteria like bacillus sp., staphylococcus sp., lactobascillus, xanthomonas. So this sugarcane filtrate is used as nutrient medium and as well as bacterial culture. Firstly the sugarcane filtrate nutrient media 2ml was added to all test tubes. Then after add different concentration like 0.5ml,1ml, 1.5ml and 2ml of Daucus carota Root extract, For this we use levofloxacin antibiotic pure API and kept for incubation for 24hours.

Preparation of Levofloxacin drug solution:

Accurately weight about 1gm of pure levofloxacin drug and dissolved in the distilled water then make up to 50ml with the distilled water in the Volumetric flask.

Figure.4: Results of Antimicrobial Activities with Daucus carota root extract.

From the Figure.4: antibacterial activity of Daucus carota root extract. We conclude that highest concentration of this extract is show more bacterial killing capability by visual conformation forming high quantity of Turbidity that is compared with the standard drug levofloxacin.so this root extract is having potential antibacterial activity.
