Question 1

Which method are used for preparation of herbal extract?
A)Sublimation
B)Digestion
C)HPLC
D)a and b

Accepted Answer

Sublimation and digestion are methods used for the preparation of herbal extracts. Sublimation involves the direct conversion of a solid to a gas without passing through the liquid phase, while digestion involves the extraction of active compounds from plant material using a solvent.

Question 2

What is the disadvantage of ultrasonic extraction
A)formation of free radicle
B)low cost
C)less time
D)all of above

Accepted Answer

Ultrasonic extraction can lead to the formation of free radicals due to the high energy involved in the process, which can potentially degrade the compounds of interest or create unwanted byproducts.

Question 3

which parameter are affect to super critical fluid extraction method
A)pressure
B)density
C)temperature
D)a and c

Accepted Answer

Super critical fluid extraction is significantly influenced by pressure and temperature, as these parameters affect the density and solvating power of the supercritical fluid, typically CO2.

Question 4

Estimation of Embelica officinalis by
A)vitali morine test
B)Total phenolic content
C)TLC
D)all of above

Accepted Answer

Embelica officinalis, commonly known as Indian gooseberry or amla, is often estimated by measuring its total phenolic content, as it is rich in phenolic compounds.

Question 5

which constituent are preseant in Allium sativum
A)Allin
B)allyl propyl amine
C)diallyl tri sulphate
D)all of above

Accepted Answer

The answer of which constituent are preseant in Allium sativum
A)Allin
B)allyl...

Question 6

what is biological source of Garcenia
A)Garcina alba
B)Garcinia cambogia
C)Garcinia officinalis
D)all of above

Accepted Answer

Garcinia cambogia is the correct biological source of Garcinia, known for its use in weight loss supplements. The other options listed do not correspond to the recognized source of Garcinia in the context of its common uses.

Question 7

which parts are involved in preparation of Alium sativum?
A)bulb of garlic
B)dried peel of cloves of garlic
C)powder of leaves of garlic
D)all of above

Accepted Answer

The answer of which parts are involved in preparation of...

Question 8

which parameter are used for evaluation of herbal drugs?
A)Viscosity
B)melting point
C)Solubility
D)all of above

Accepted Answer

All of the options listed, viscosity, melting point, and solubility, are parameters used in the evaluation of herbal drugs to determine their physical and chemical properties, ensuring quality, efficacy, and safety.

Question 9

Gas Chromatography depend on
A)Adsorption
B)Absorption
C)differential migration
D)all of above

Accepted Answer

Gas chromatography relies on differential migration, where components of a mixture are separated based on their different rates of travel through a stationary phase under the influence of a mobile phase.

Question 10

what is the principal of HPTLC?
A)adsorption
B)partition
C)absorption
D)a and b

Accepted Answer

HPTLC, or High-Performance Thin-Layer Chromatography, operates on the principles of both adsorption and partition. The stationary phase can adsorb compounds, and the mobile phase can create a partitioning environment for the separation of components.

Question 11

Which drug is used for reduce production of fat?
A)Amla
B)Garcenia
C)Aswagandha
D)all of above

Accepted Answer

Garcinia, specifically Garcinia cambogia, contains hydroxycitric acid (HCA) which has been shown to inhibit the conversion of carbohydrates into fat, thereby potentially reducing fat production.

Question 12

what is family of Garcenia?
A)Guttiferae
B)apoyneceae
C)Rubiaceae
D)leguminoseae

Accepted Answer

Garcinia belongs to the family Guttiferae (also known as Clusiaceae). This family includes various species known for producing fruits and resins.

Question 13

what is basic requirement of hot contineous extraction method?
A)thimble
B)condenser
C)filter paper
D)all of above

Accepted Answer

The basic requirement of the hot continuous extraction method includes a thimble to hold the sample, a condenser to cool and condense the solvent vapors, and filter paper to separate the solid particles, making all of the above correct.

Question 14

Microwave assisted extraction method are
A)energy vector
B)electromagnetic energy
C)a and b
D)preparation of antibodied

Accepted Answer

Microwave assisted extraction method uses both energy vector and electromagnetic energy.

Question 15

which method is used for evaluation of alkaloid?
A)wagner's method
B)balget test
C)legal test
D)killer killiani test

Accepted Answer

Wagner's method is a chemical test used for the detection and evaluation of alkaloids.

Question 16

Evaluation of drugs include
A)Microscopy
B)Macroscopy
C)Chemical reaction
D)All

Accepted Answer

Evaluation of drugs includes a variety of techniques such as Microscopy (for examining the microscopic details of a drug), Macroscopy (for examining the physical characteristics of a drug without the aid of a microscope), and Chemical reactions (for identifying chemical constituents and verifying the identity or purity of a drug). Therefore, all the options listed are correct.

Question 17

Microbial toxins includes
A)Mycotoxins
B)Endotoxins
C)Both a and b
D)None

Accepted Answer

Mycotoxins are toxins produced by fungi, while endotoxins are toxins that are part of the outer membrane of the cell wall of Gram-negative bacteria. Both are types of microbial toxins.

Question 18

Full form of ADI is
A)Acceptable diet intake
B)Acceptable daily intake
C)Acceptable daily interaction
D)Acceptable diet interaction

Accepted Answer

The full form of ADI is Acceptable Daily Intake. It refers to the maximum amount of a substance (such as a food additive, pesticide residue, or pharmaceutical) that can be ingested daily over a lifetime without posing a significant risk to health.

Question 19

MDI means
A)Mean daily interaction
B)Mean daily intake
C)Mean diet intake
D)Mean diet interaction

Accepted Answer

MDI stands for Mean Daily Intake, which refers to the average amount of a substance (such as nutrients, drugs, or chemicals) consumed per day.

Question 20

Components of GMP includes
A)Training staff
B)Quality control of finished product
C)Quality control of raw material
D)All

Accepted Answer

Good Manufacturing Practice (GMP) guidelines encompass all these components: training staff to ensure they are competent and understand their roles, quality control of raw materials to ensure they meet the necessary standards before being used in production, and quality control of the finished product to ensure it is safe and meets the specified quality criteria.
