      Identification and separation of Cannabis sativa, Embleia ribes, Myristica fragrans and Piper longum from organic extract on silica gel surface with anionic micellar solvent system
      A. MOHAMMAD*, S. SHARMA, S. BHAWANI, R. SINGH (*Analytical Research Lab., Dept. of Applied Chem., Faculty of Eng. & Tech., Aligarh Muslim University Aligarh 202002, India)

      The Open Nutraceuticals Journal 2, 2-6 (2009) A TLC method using a micellar solution of sodium dodecyl sulfate (SDS) as mobile phase has been developed for identification of four herbals present in Jatiphaladya, a powdered herbal formulation containing Cannabis sativa, Myristica fragrans, Piper longum, and Embleia ribes. The formulation was extracted with 80 % ethanol. TLC on laboratory made plates coated with silica gel and activated at 100 °C for 60 min, with a 5 % solution of SDS as mobile phase. The resolved spots were identified by spraying with a 2 % solution of vanillin in 5 % methanolic sulfuric acid. Spots corresponding to different herbals were well resolved. Different detection reagents were evaluated, i.e. iodine, vanillin sulfuric acid, and anisaldehyde-sulfuric acid. Vanillin sulfuric acid reagent was found to be the most sensitive. Of the different surfactants used, anionic, cationic and nonionic, SDS was found to be most suitable. The most suitable pH of the mobile phase was pH 4.2-5.7, it provided optimum resolution of zones.

      J.D. VASTA*, J. SHERMA (*Lafayette College, Department of Chemistry, Easton PA 18042-1782, USA)

      Acta Chromatographica 20(4), 673-683 (2008). Presentation of a quantitative method for the analysis of lycopene in nutritional supplements consumed to reduce the risk of prostate cancer and other forms of cancer and cardiovascular disease. HPTLC on silica gel with petroleum ether – dichloromethane 9:1. Quantification by densitometry at 416 nm. Four products containing 300 µg, 3 mg, 5 mg, or 10 mg lycopene plus other ingredients were quantified using a lycopene standard: the measured amounts ranged from 77.7 to 98.1 % of the stated label values. The accuracy by spiked blank analysis was within 1.90 % of theoretical values for the 3 mg softgels and 1.10 % of theoretical values for the 10 mg softgels. The precision of replicate analyses showed a RSD of 1.44 % for the 10 mg softgels and 2.39 % RSD for the spiked blank for the 3 mg softgels. The results obtained for Lycopene standards available from two other companies showed 55.6, 57.6, and 20.0 % of the minimum amount expected from the stated label values.
