Indian Drugs 44 (3), 205-208 (2007). HPTLC of frusemide (= furosemide) and spironolactone on silica gel with toluene - acetonitrile - glacial acetic acid 70:30:2, with chamber saturation for 15 min at room temperature. Development over 8 cm, followed by air drying. Quantitative determination by densitometry at 254 nm. Linearity was between 8 - 32 ng/µL and 20 - 80 ng/µL for frusemide and spironolactone respectively. The method was validated for accuracy and precision. The limit of detection and quantification for frusemide was 3 ng/µL and 8 ng/µL respectively, and for spironolactone 2 ng/µL and 6 ng/µL, respectively. Recovery by standard addition was 99.4-101% for both compounds.

TLC of Shajun Zhiyang lotion on silica gel with 1) benzene - ethyl acetate - isopropanol - methanol - ammonia 12:6:3:3:1; 2) benzene - ethyl acetate 30:1; 3) ethyl acetate. Detection 1) under UV 365 nm; 2) by spraying with 5% vanillin in H2SO4 solution and heating at 105 °C. Identification by fingerprint techniques. Quantification of matrine by HPLC.

Indian Drugs 44(10), 734 (2007). HPTLC of valdecoxib on silica gel with toluene - ethyl acetate 1:1. Quantitative evaluation by densitometry at 262 nm. Valdecoxib was well separated from rofecoxib. Linearity was between 800 and 1000 ng/zone. Recovery was 98.9 %.

59th Indian Pharmaceutical congress F-54, 402, (2007). HPTLC of amlodipine besylate and bisoprolol on silica gel with methanol - ethyl acatete - ammonia 1:12:1. Densitometric evaluation at 229 nm. The method was linear in the range of 500-1000 ng/zone. Recovery was 99.9 -101.5 %.

59th Indian Pharmaceutical congress F-224, 443, (2007). HPTLC of cilostazol on silica gel with ethyl acetate - toluene - methanol - ether 4:4:2:1. The hRf value was 64. Limit of detection and quantification was 7 ng/spot and 20 ng/spot respectively.

Chromatographia 66 (9-10), 801-804 (2007). HPTLC of withaferin A and withanolide A in Withania somnifera methanolic extract from different plant parts (leaf, root, stem and fruit) and of two morphotypes, on silica gel with toluene - ethyl acetate - formic acid 5:5:1. Quantification by densitometry in absorption mode at 530 nm. Linearity was between 200 and 3200 ng for both withaferin A and withanolide A. The average recovery of withaferin A and withanolide A was 96.0 and 96.7 %.

Chromatographia 68 (1-2), 151-153 (2008). Anisaldehyde and crotonaldehyde reagent are suitable as spray reagents for the detection of major components of sesame oil unsaponifiables. Derivatization with anisaldehyde reagent lead to chromatograms with coloured zones characteristic for lignans and sterols in Sesamum indicum. By derivatization with crotonaldehyde four of the eleven unsaponifiable matters could be detected as more stable and brightl coloured zones. The results obtained could serve as a guide in the monitoring of oil’s stability, adulteration and contaminations.

Ind. J. Pharm. Res. 6 (4), 205-207 (2007). HPTLC of itraconazole on silica gel with toluene - acetone - triethylamine 30:30:1. Detection at 270 nm. The hRf value of itraconazole was 62. Linearity was between 0.2 and 0.6 µg. The market formulation contained itraconazole amounts of 99.6 % via peak height and 100.2 via peak area, respectively. Recovery (by standard addition) was 99.4 % and 100.3 % respectively.
