      J. Chromatogr. A 1530, 192-196 (2017). HPTLC to measure the antioxidant and hypoglycemic effects in different extracts from Myrmecodia platytyrea, which can be a traditional medicine as alternative treatment for diabetes, because the substances produced by ants can reduce blood sugar levels. Measurement of the antioxidant activity in methanol, ethanol, dichloromethane (DCM) and ethyl acetate (EA) extracts with the HPTLC-2,2-diphenyl-1-picrylhydrazyl free radical (DPPH*) assay, and of the hypoglycemic effects with a newly developed α-amylase inhibitory activity assay. Detection of stigmasterol after derivatization with anisaldehyde reagent as purple colored zone under white light at hRF 66. The results showed the highest antioxidant activity in the ethanol extract rich in polyphenols and flavonoids. No antioxidant activity but significant α-amylase inhibitory activity was observed in the DCM extract. The highest α-amylase inhibitory activity was found in the EA and DCM extracts and was related to their stigmasterol content.

      Anita SURENDRA PATIL*, H. MADHUKARRAO PAIKRAO, A. SUBHASH KALE, S. RAGHOBA MANIK (*Lab No. 106, Plant Secondary Metabolite Lab, Dep. of Biotechnol., Sant Gadge Baba Amravati Univ., Amravati, 444602 Maharashtra, India, anitapatil@sgbau.ac.in)

      J. Chromatogr. Sci. 55 (5), 571-577 (2017). Proposal of a rapid, easy and efficient method for calcium oxalate crystal inhibition in the agar gel system analogous to antimicrobial well diffusion assay, and TLC-agar-overlay bioautography (note that the term "direct bioautography" is wrongly used in the title) to detect the antilithiatic metabolites and to localize the active metabolites in Phyllanthus niruri, an Ayurvedic plant. The agar well diffusion method showed 50 % inhibitory concentration (IC50) value at 229 and 494 mg/mL for tri-sodium citrate and Phyllanthus niruri extract, respectively, with the lowest concentration showing visible crystal inhibition (minimum inhibitory concentration, MIC) of 20 mg/mL in both samples. With this method the successful screening, detection and confirmation of calcium oxalate crystal inhibitory metabolites from P. niruri was possible. Detection of tuberonic acid in the bioactive fraction of P. niruri by HPLC-HRMS.
