HPTLC was performed on precoated silica 60F<jats:sub>254 <\/jats:sub>plates with dichloromethane\/methanol\/water 75:17:2.2 by volume, as mobile phase. Evaluation of the HPTLC plates was done by using the CAMAG DigiStore2 digital system with winCATS software. The authentication of <jats:italic>H. gordonii <\/jats:italic>was achieved by comparing the band colors and <jats:italic>R<\/jats:italic><jats:sub>f<\/jats:sub> values for TLC fingerprints with those of 11 standard compounds including P57. The developed method was successfully applied for the identification of the 11 pregnane glycosides for four different species of<jats:italic> Hoodia<\/jats:italic>, 24 related genera and 13 dietary supplements that claim to contain<jats:italic> H. gordonii<\/jats:italic>. Different sample matrices were successfully analyzed, providing a wide range of applicability for this method, including gels, capsules, tablets, sprays, teas, snack bars, powders, and juices. The developed method was validated for specificity, stability, repeatability, and robustness. The results of HPTLC method were verified by LC\u2010UV\u2010MS method.<\/jats:p>","DOI":"10.1002\/jssc.200800441","type":"journal-article","created":{"date-parts":[[2008,12,8]],"date-time":"2008-12-08T05:35:00Z","timestamp":1228714500000},"page":"3959-3964","source":"Crossref","is-referenced-by-count":19,"title":["Chemical fingerprint of <i>Hoodia<\/i> species, dietary supplements, and related genera by using HPTLC"],"prefix":"10.1002","volume":"31","author":[{"given":"Chidananda Swamy","family":"Rumalla","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bharathi","family":"Avula","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yatin J.","family":"Shukla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan\u2010Hong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rahul S.","family":"Pawar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Troy J.","family":"Smillie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikhlas A.","family":"Khan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,12,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.phytochem.2007.05.022"},{"key":"e_1_2_1_3_2","unstructured":"Anonymous Consumer Rep.2006 71 49."},{"key":"e_1_2_1_4_2","doi-asserted-by":"crossref","unstructured":"Anonymous Bulletin of the World Health Organization2006 84 345.","DOI":"10.2471\/BLT.05.029132"},{"key":"e_1_2_1_5_2","unstructured":"Van Heerden F.
