J Young Pharm 1(3), 259-263 (2009). A validated HPTLC method is described for simultaneous estimation of amlodipine besylate and telmisartan in dosage form. HPTLC on silica gel with tetrahydrofuran - dichloroethane - methanol - 25 % ammonia solution 60:20:10:4. The hRf value of amlodipine besylate was 45 and of telmisartan 22. Densitometric evaluation at 326 nm. Linearity was in the range of 1200-7200 ng/band for telmisartan and 400-1400 ng/band for amlodipine besylate. The limit of detection was 149 ng/zone and 53 ng/zone for telmisartan and amlodipine besylate, respectively. The limit of quantification was 453 ng/zone for telmisartan and 161 ng/zone for amlodipine besylate. The recovery was between 100.4 and 100.8 %.
International Journal of Pharma World Research 1(2) (2010). A validated stability indicating assay method is described for estimation of voglibose in bulk and dosage formulation. TLC on pre-washed silica gel plates with acetonitrile - methanol - 25 % ammonia 150:40:1. The hRf value of voglibose was 66. Densitometric evaluation at 284 nm. The method was linear in the range of 100-450 ng/band. The average recovery was 101.4 %.
J. Pharma. Sci. & Res. 2(8), 477-483 (2010). TLC on silica gel with ethyl acetate - glacial acetic acid - methanol - water 10:5:3:2. The hRf value was 51 and 74 for amoxicillin and bromhexine, respectively. Densitometric evaluation at 260 nm (bromhexine) and at 320 nm (amoxicillin). The method was linear in the range of 200-1000 ng/band and 10-30 µg/band for bromhexine and amoxicillin, respectively. The recovery was between 98.1-101.5 %.
Rec. Nat. Prod. 3/4, 178-186 (2009). An HPTLC method has been reported for quantitative estimation of alpha-mangostin in fruit pericarp of Garcinia mangostana (Hypericaceae). HPTLC on silica gel with chloroform - methanol 9:1 in a saturated chamber (10 min). The plate was derivatized with anisaldehyde sulfuric acid reagent. Densitometric quantification at 382 nm. Alpha-mangostin was detected as a compact band with hRf value of 46. The method was linear in the range of 1-5 µg/band. The maximum yield of alpha-mangostin was obtained from the plant by hot extraction with methanol.
Journal of Pharmaceutical Research 9(2), 60-62 (2010). TLC on silica gel with chloroform - ethyl acetate - methanol - ammonia 20:20:10:1 with chamber saturation for 30 min. Densitometric evaluation at 232 nm. The method was linear in the range of 100-800 ng/band for amlodipine, 400-2400 ng/band for hydrochlorothiazide and 1000-8000 ng/band for amlodipine. The average recovery was 99.1-100.4 % for all three compounds. The method was suitable for stability studies (stress conditions: acid, base, thermal, UV).
62nd Indian Pharmaceutical Congress Abstract No. F-240 (2010). TLC of escitalopram oxalate on silica gel with n-butanol – acetic acid – water 3:1:1. Quantitative determination by absorbance measurement at 240 nm. The method was linear in the range of 100-600 ng/band.
Int. J. Pharma. Sci. 2(1), 390-394 (2010). TLC of salbutamol sulphate (SS), ambroxol hydrochloride (AH), and theophylline (THE) in a ternary fixed dose formulation on hand made silica gel plates with methanol – n-hexane 21:9. The hRf values were 25 for SS, 72 for THE and 89 for AH. Detection under UV 254 nm and by exposure to iodine vapors. The bands of the respective compounds were scraped off and quantified by spectrophotometry.
62nd Indian Pharmaceutical Congress Abstract No. F-266 (2010). TLC of metformin and pioglitazone, extracted with methanol from bulk and pharmaceutical formulation, on prewashed silica gel with toluene – methanol – triethylamine 40:10:1. The hRf values of metformin and pioglitazone were 25 and 50, respectively. Quantitative determination by absorbance measurement at 230 nm. The linearity was in the range of 100-1000 ng/band for metformin and 200-1200 ng/band for pioglitazone: the correlation coefficients (r) were 0.9958 and 0.9992, respectively.
