Background: Argyreia sericea Dalzell (Convolvulaceae) is a densely hirsute stout climbing shrub found throughout the dry deciduous forests of India. A. sericea is morphologically related to Argyreia nervosa (Burm.f.) Bojer and Argyreia involucrata C.B.Clarke which are used in traditional systems of medicine for treatment of various diseases. As related species look similar in dried form. Objectives: A macro-microscopic and HPTLC study was planned on whole plant parts of A. sericea to analyze key distinguishing characters. Materials and Methods: Standard pharmacopoeial procedures were employed to obtain all the results of the study. Results: Surface characters, odour and taste; transverse section of leaf, stem, root and stomata of epidermal cells, cluster crystal, trichomes, mesophyll tissue, laticiferous content, brownish content, fibres, starch grains, tracheids, fibres tracheids, pitted vessels with scalariform perforation along with pitted, spiral and annular thickening are the unique diagnostic characters observed. Fingerprint profile with unique Rf obtained by HPTLC will aid in correct identification of the species. Conclusion: The findings of the present study will be helpful in identification and differentiation from related species as whole drug or in powder from.

Introduction: Maranta arundinacea L. (arrowroot) starch is readily available in the market owing to its soaring demand in the pharma and food industry. Despite its cost in extraction methods and minimal yield, it is marketed at cheaper rates. The unclear picture of its authenticity, quality and the high chances of adulteration are still unexplored. This case study is planned to identify and authenticate genuine and adulterated samples of Maranta Starch (MS) procured from various vendors in comparison with a Botanical Reference Standard (BRS) and In-House preparation (IH). Materials and Methods: The BRS, IH and nine commercial samples (labeled as MS 1 to 9) were subjected to a systematic approach of powder microscopy, preliminary physiochemical assays and X-ray Diffraction (XRD). Results: On gross examination, the texture, color, odor and taste of samples showed minute differences, however, the powder microscopy and iodine test demonstrated significant differences. The samples which reported more deviation were tested and confirmed for the presence of inorganic matter through an ash test. This was further studied for XRD analysis, which reported major adulterants in the samples like dolomite (CaMg (CO3)2), cordierite (Al4Mg2Si5O18), quartz (SiO2) and Zinc Sulphide (ZnS). Conclusion: This case study reveals the extensive adulteration of marketed MS in the South Indian market, particularly Chennai.
