Soluble in water and in ethanol (99.5) and sparinglysoluble in methanol. Melting point: about 250ºC (withdecomposition).1%Absorbance E 1cm (230 nm): 217 - 231 (5 mg calculatedon <strong>the</strong> anhydrous basis, methanol, 200 mL)Purity Related substances—Dissolve 1.0 mg of benzoylmesaconinehydrochloride for thin-layer chroma<strong>to</strong>graphy in exactly1 mL of ethanol (99.5). Perform <strong>the</strong> test with 5 µL of thissolution as directed in <strong>the</strong> Identification under Processed AconiteRoot: no spot o<strong>the</strong>r than <strong>the</strong> principal spot at around R f 0.4appears.Bergenin for thin-layer chroma<strong>to</strong>graphy C 14 H 16 O 9·xH 2 OWhite crystals or crystalline powder. Slightly soluble in ethanol(99.5), very slightly soluble in water, and practically insoluble indiethyl e<strong>the</strong>r.Identification Determine <strong>the</strong> absorption spectrum of a solutionof bergenin for thin-layer chroma<strong>to</strong>graphy in methanol (1 in50000) as directed under Ultraviolet-visible Spectropho<strong>to</strong>metry: it exhibits maxima between 217 nm and 221 nm, andbetween 273 nm, and 277 nm, and a minimum between 241nmand 245 nm.Purity Related substances—Dissolve 1.0 mg of bergenin forthin-layer chroma<strong>to</strong>graphy in 1 mL of methanol. Perform <strong>the</strong>test with 20 µL of this solution as directed in <strong>the</strong> Identificationunder Mallotus Bark: no spot o<strong>the</strong>r than <strong>the</strong> principal spot at <strong>the</strong>R f value of about 0.5 appears.(E)-Capsaicin for thin-layer chroma<strong>to</strong>graphy C 18 H 27 NO 3White crystals, having a strong irritative odor. Very soluble inmethanol, freely soluble in ethanol (95) and in diethyl e<strong>the</strong>r, andpractically insoluble in water.Melting point : 65-70ºC.Purity Related substances—Dissolve 20 mg of(E)-capsaicin for thin-layer chroma<strong>to</strong>graphy in 2 mL of methanol,and use this solution as <strong>the</strong> sample solution. Pipet 1 mL ofthis solution, add methanol <strong>to</strong> make exactly 100 mL, and usethis solution as <strong>the</strong> standard solution. Perform <strong>the</strong> test with 10µL each of <strong>the</strong> sample solution and standard solution as directedin <strong>the</strong> Identification under Capsicum: any spot o<strong>the</strong>r than <strong>the</strong>principal spot at <strong>the</strong> R f value of about 0.5 from <strong>the</strong> sample solutionis not more intense than <strong>the</strong> spot from <strong>the</strong> standard solution.Add <strong>the</strong> following:Acemetacin C 21 H 18 ClNO 6 [Same as <strong>the</strong> namesake monograph]Acemetacin for assay C 21 H 18 ClNO 6 [Same as <strong>the</strong> monographAcemetacin. When died, it contains no less than 99.5% ofacemetacin (C 21 H 18 ClNO 6 ) meeting <strong>the</strong> following additionalspecifications.]Purity Dissolve 40 mg of acemetacin for assay in 10 mL ofmethanol, and use this solution as <strong>the</strong> sample solution. Pipet 1mL of this solution, and add methanol <strong>to</strong> make exactly 10 mL.Pipet 1 mL of this solution, add methanol <strong>to</strong> make exactly 20mL, and use this solution as <strong>the</strong> standard solution. Perform <strong>the</strong>test with exactly 10 µL each of <strong>the</strong> sample solution and standardsolution as directed under Liquid Chroma<strong>to</strong>graphy according<strong>to</strong> <strong>the</strong> following conditions. Determine each peak areaof both solutions by <strong>the</strong> au<strong>to</strong>matic integration method: <strong>the</strong> areaof each peak o<strong>the</strong>r than acemetacin is not larger than 1/2 times<strong>the</strong> peak area of acemetacin obtained from <strong>the</strong> standard solution,and <strong>the</strong> <strong>to</strong>tal area of <strong>the</strong> peaks o<strong>the</strong>r than <strong>the</strong> peak of acemetacinis not larger than <strong>the</strong> peak area of acemetacin from <strong>the</strong> standardsolution.Operating conditionsDetec<strong>to</strong>r, column, column temperature, mobile phase, andflow rate: Proceed as directed in <strong>the</strong> operating conditions in <strong>the</strong>Assay under Acemetacin Tablets.Time span of measurement: About 4 times as long as <strong>the</strong> retentiontime of Acemetacin.System SuitabilityTest for required detectability: Pipet 1 mL of <strong>the</strong> standard solution,and add methanol <strong>to</strong> make exactly 20 mL. Confirm that<strong>the</strong> peak area of acemetacin obtained from 10 µL of this solutionis equivalent <strong>to</strong> 3 <strong>to</strong> 7% of that of acemetacin from <strong>the</strong> standardsolution.System performance: Dissolve 75 mg of acemetacin and 75
