Cultivation ,collection , preparation

Propogated by seed

Needs sandy or siliconous soil with humus (dark organic material in soils, produced by the decomposition of vegetable or animal matter and essential to the fertility of the earth.)

Annual rainfall of 200-250cm is ideal with sheltered area.

Seed sown in nursery bed in june /july, takes 20 days for germination of seeds .seedling allowed to grow for 10-12 months in shade.

seedlings transplanted in rainy season at about distance of 2 meters in beetween plants .

Adequate fertilizers are provided and plant kept free from weed.

Trees are coppiced ( young tree stems are repeatedly cut down to near ground level. In subsequent growth years, many new shoots will emerge to induce formation of shoots.)

Bark is peel off in rainy season from shoot by giving longitudinal incisions.

Bark strips are bundle,wrapped in coir matting and allowed to ferment for 24 Hours.

Fermentation looses outer cork and cortex so it can be removed by scrapping.

during drying bark contract and converted to quill

Smallers quills inserted in to larger quills to form compound quill.

fresh quills are rolled and slightly pressed to avoid swelling and splitting in to pieces

Finally drug is dried in shade over mats.

Macroscopic characteristics1-colour- outer surface dull yellowish-brown, inner surface dark yellowish brown

2-Odour- fragrant

3-Taste- aromatic and sweet followed by worm sensation

. They melt at high temperature and form transparent bead.

Used for filters fabric .

Asbestos-

it is hydrated aluminium silicate.

Highly refractive and do not fuse when heated.

Used for filtering medium and for bacterial filters

polyster

polymers which contain the ester functional group in their main chain.

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, thermoplastic polymer resin of the polyester family and is used in synthetic fibers

Polyester is also wrinkle resistant and is used very often in everyday clothing

Its hydrophobic property makes it ideal for garments and jackets that are to be used in wet or damp environments--coating the fabric with a water-resistant finish intensifies this effect.

In preparation of dusting powder and for coating, dusting pills

naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder.

DIATOMITE

naturally occurring, so is the skeletal remains of single celled plants called diatoms, hence the name diatomite.

These microscopic algae have the capability of extracting silica from water to produce their skeletal structure.

When diatoms die their skeletal remains sink to the bottom of lakes and oceans and form a diatomite deposit.

diatomite

Synonym-diatomaceous earth, kieselguhr

Source-it consist of silica material with organic matter of fossil diatoms of

family Bacillariaceae, it is subdivision of algae

Geographical source-

Large amount in california,

virginia,

germany,

denmark,

algeria

, north america

Collection and preparation-

Diatomite deposite have developed over time due to faster growth and later death of diatoms

.it accumulates as huge siliceous skeletons of fossilediatoms at the bottom of sea or in fresh water lake

.it is present as large blocks.

These blocks are dried after collection.

These blocks then crushed in mills and shifted through machines to obtain fine powder.

It purified by dil HCL , washed till neutral and dried

Charecterstics-

Colour-buff to grayish brown

Odour- odorlessNontoxicconsistency of powdered chalk or flourIt becomes white after treatment with acid.

Soluble in most of acids.it is highly absorbent

Chemical constituents-

75 to 92% silica,

1 to 6 % aluminium oxide.

Purified kieselguhr contains- only silicon oxide

Uses-

Filtration aid,

for clarification and decolourisation of syrups, oils, fats.

.adsorbent in chromatography,

manufacture of tooth powder, talcum powder, nail polish, pills, soaps.

BENTONITE

Montmorillonite is a very soft phyllosilicate group of minerals that typically form in microscopic crystals, forming a clay

Bentonite is an absorbent aluminium phyllosilicate[ silicate minerals ]impure clay consisting mostly of montmorillonite.

BENTONITE

Synonym-bentonitum,soap clay, wilkinite

Source-it is deposit of mineral which resembles clay.

Geographical source-italy, canada, south africa. Best variety obtain in usanear fort benton hence its name

Collection and preparation-

mineral collected from mines,

dried by steam and powdered by machine,

shifted to obtain fine powder bentonite.

Charecterstics-

colour- buff to greyish green

Insoluble in water but absorbs about six times its weight of water,

swells to about 12 to 15 times its volume.

Its aqueous dispersion is alkaline to litmus.

It stains deep red with safranin

Chemical constituents-

It is mineral of aluminium and silicon oxide montmorillonite

Uses-

Used for preparation of gel used for preparation of emulsion, ointment, creams.

Used in lipsticks

KAOLIN

kaolin

is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4.

It is a layered silicate mineral,Rocks that are rich in kaolinite are known as kaolin or china clay.

Synonym- Heavy or light kaolin, China clay, bolus alba, porcelain clay, white bole, argilla

(hydrated aluminum silicate)

The name is derived from Chinese Kao-Ling , a village from which it was mined for centuries.

It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar[ group of rock-forming tectosilicate minerals]

is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other

uses

filtering agent to clarify liquids.

internally to control diarrhea. Kaolin has also been used topically as an emollient and drying agent.

About 20 million tonnes of feldspar were produced in 2010, mostly by three countries: Italy (4.7 Mt), Turkey (4.5 Mt), and China

gelatin

GELATIN

Gelatin is a mixture of peptides and proteins produced by partial hydrolysis of collagen extracted from the skin, bones, and connective tissues of animals

pharmaceutical grades of gelatin are generally sourced from beef bones.

Gelatin forms a viscous solution when dissolved in hot water, which sets to a gel on cooling. Gelatin added directly to cold water does not dissolve well. Gelatin is also soluble in most polar solvents.

manufacturing processes

-Pretreatments to make the raw materials ready for the main extraction step and to remove impurities which may have negative effects on physio chemical properties of the final gelatin product,

-The main extraction step, which is usually done with hot water or dilute acid solutions as a multi-stage extraction to hydrolyze collagen into gelatin, and finally,

-The refining and recovering treatments including filtration, clarification, evaporation, sterilization, drying, rutting, grinding, and sifting to remove the water from the gelatin solution, to blend the gelatin extracted, and to obtain dried, blended and ground final product.

If gelatin is derived from bones, dilute acid solutions are used to remove calcium and other salts.

Hot water or several solvents may be used in order to reduce the fat content, which should not exceed 1% before the main extraction step.

Collagen hydrolysis is performed by one of three different methods: acid-, alkali-, and enzymatic hydrolysis.

gelatin is used primarily to make hard and soft gelatin capsules.

Other uses include manufacturing tablets, emulsions, suppositories and syrups
