'''Description''' : Mostly crumpled and rolled, sometimes broken. When whole, long elliptical to oblong-oblanceolate 5 - 20cm long, 2 - 6cm wide, upper surface dark greyish green, sometimes small deeper coloured prominences being visible, apex obtuse, margins entire or slightly undulate, base attenuate and decurrent into the petiole appearing wing shaped, petioles 4 - 10 cm long, pale brownish yellow. Texture fragile, odour slight, taste slightly sour, bitter and astringent.<BR><BR><br />
'''Identification''' : 1.Powder: greenish brown, anticlinal walls of lower epidermal cells slightly sinuous and somewhat beaded, stomata anomocytic, with 3 - 4 subsidiary cells. Transverse section of mesophyll indistincly differentiated into palisade tissue and spongy tissue.2.To 0.5g of the powder add 20ml of chloroform, heat under reflux on a water bath for 1 hour, filter and evaporate the filtrate to 1ml as the test solution. Dissolve indigotin CRS and indrirubin CRS in chloroform to produce a solution containing 1mg of each per ml as the reference solution. Carry out the thin layer chromatography (Appendix Vl B), using silica gel G as the coating substance and benzene-chloroform acetone (5:4:1) as the mobile phase. Apply separately to the plate 5µl of the two solution. After developing and removal of the plate, dry it in tha air. The blue spot and pale purplish red spot due to indigotin and indirubin in the chromatogram obtained with the test solution correspond in position and color to the spots in the chromatogram obtained with the reference solution<BR><BR><br />
'''Processing''' : Eliminate foreign matter, wash rapidly, cut into pieces and dry. <BR><BR><br />
'''Action''' : To remove toxic heat, reduce heat in blood, and to promote subsidence of eruptions.<BR><BR><br />
'''Indication''' : high fever with impairment of consciousness with skin eruptions in epidemic disease, jaundice, acute dysentery, mumps, inflammation of the throat, erysipelas, carbuncle <BR><BR><br />
'''Precautions''' : <BR><BR><br />
'''Dosage''' : 9 to 15 g.<BR><BR><br />

'''Chinese Name''' : <BR><BR><br />
'''Common Name''' :Natural Indigo<BR><BR><br />
'''Specific Name''' : Indigo naturalis<BR><BR><br />
'''Scientific Name:'''<BR><br />
'''Collection''' : <BR><BR><br />
'''Description''' : Description: a deep blue powder, light and pufffy or irregular and porous masses, finely powdered on twisting, odour slightly grassy and taste weak.<BR><BR><br />
'''Identification''' : 1.Burn gently small quantity of powder, a purplish red smoke is produced.2.To a small quantity of the powder, add nitric acid dropwise, a brownish red or yellowish brown colour s produced with effervescence.3.To 50mg of the drug add 5ml of chloroform, stir well and filter, the filtrate used as the test solution. Dissolve indigo CRS and indirubin CRS in chloroform to prepare a solution containing 1mg of each per ml. Use as the reference solution. Carry out the method for thin layer chromatography (Appendix Vl B), using silica gel G as the coating substance and benzene-chloroform-acetone (5:4:1) as the mobile phase. Apply separately to the plate 5 - 10µl of each of the two solutions. After developing and removal of the plate, dry it in the air. The blue spot and pale purplish red spot in the chromatogram obtained with the test solution correspond in position and colour to the spots in the chromatogram obtained with the reference solution.Water soluble pigment: Shake 0.5g of the powder with 10 ml of water and allow to stand for a moment, the water layer shows no deep blue colour.Assay: Reference preparation: Sulfonate 20mg of indigo CRS accurately weighed in a flask by adding 15ml of sulfuric acid slowly and with a constant stiring gently on a water bath at 80ºC for 1 hour. Allow to cool, transfer the solution slowly to a 200ml volumetric flask containing a quality of water. Wash the flask and the residue with water. Combine the washing to a volumetric flask, add water to volume and mix well. Filter and discard the initial filtrate. Measure accurately 5ml of the successive filtrate to a 50ml volumetric flask, add water and mix well (containing 10µg of indigo per ml.Preparation of standard curve: Measure accurately 1.0, 2.0, 3.0, 4.0, and 5.0ml of the reference solution respectively into a 10ml volumetric flask, add water to volume and mix well. Carry out the method for spectrophotometry (Appendix V B). Measure the absorbance at 610nm and plot the standard curve using the absorbance as ordinate and concentration abscissa.Procedure: Weigh accurately 0.4g of the fine powder, carry out the procedure as described under reference preparation, beginning at the words "in a flask [[User:Media wiki admin|Media wiki admin]] 13:21, 29 November 2012 (EST)" to" discard the initial filtrate, measure accurately 5ml of the successive filtrate". Transfer the filtrate to a 50ml or 100ml volumetric flask (adjust the absorbance to be within 0.20 - 0.45), add water to volume and mix well. Measure the absorbance at 610nm and read out the weight of indigo (µg) in the test solution from the standard curve and calculate the percentage content of C16H10N2O2. It contains not less than 2.0% of Indigo.<BR><BR><br />
