How do you dilute plant extracts?

To make your stock solution, weigh out the exact quantity of extract you have. Assuming you have 0.20g of extract, it will be equivalent to 200mg. To make a 100mg/ml stock you just add 1ml to each 100mg of your extract.

How do you make mg/ml solution from powder?

Dry your plant extract into a powder. Then weigh 1 mg extract powder and add into 1 ml water. Freeze dry the plant extract into powder and redissolve 1 mg of the powder in 1 mL water or solvent.

How do you make a 10 ml solution?

To prepare a concentration of 10 µg/ml, pipette out 10 µl of the drug in a test tube using a micropipette. Then dilute it with 990 µl (making a total volume of 1 ml) of the solvent (ethanol, methanol, water etc) you are going to use in your experiment.

How do you measure plant extract concentration?

Most scientific papers have stated the formula for extraction yield calculation like this, The yield of extract (extractable components) expressed on dry weight basis of pulp was calculated from the following equation: Yield (g/100 g) = (W1 × 100)/W2 where W1 is the weight of the extract residue obtained after solvent …

How do you find the concentration of a plant extract?

For the determination of extract concentration you need to evaporate the solvent (by vacuum evaporator or lyophilisator) and than dissolve the crude extract in the known volume. Usually the concentration used is 1 mg/mL so it is easier to compare the result with those published by other authors.

What is mg/mL concentration?

Milligrams per milliliter (mg/mL) is a measurement of a solution’s concentration. For example, a salt water solution of 7.5 mg/mL has 7.5 milligrams of salt in each milliliter of water. To find the concentration of a solution, divide the dissolved mass by the volume of the solution.

How do I make a 50 ug mL solution?

Yes make the units the same. So convert 100 mg/mL into ug/mL = 100,000 ug/mL. You will now see that your stock requires a 10000x dilution to reach 10 ug/mL and will require a 2000x dilution to reach 50 ug/mL. You can use c1v1=c2v2 to determine the volumes required to perform the dilutions.

What is concentration of plant extract?

How do you extract flavonoids from plants?

The most used solvents for the extraction of flavonoids are ethanol, mixtures with water at different proportions, and natural deep eutectic solvents (NADES), which are based on their ability to solubilize moderately polar flavonoids with a relatively low cost and environmental impact.

Is plant extract homogeneous or heterogeneous?

Firstly, the phytochemical extracts are highly heterogeneous due to the presence of a mixture of different bioactive components. A desired biological response may not be due to a single bioactive compound, but to a mixture of several bioactive compounds.

What percentage is 50mg mL?

Percent solutions all are 1000mg/100cc. For example a 2\% = 20mg/cc, 5\% = 50mg/cc, 5.5\% = 55mg/cc, etc……
