Does any one else have any experience with this. (Ref-Rynearson,James. Curtright,Robert: Analysis of plant pigments of chromatography.) Help, please, research project on phenolphthalein poisoning. Need info on false positive and false negative drug and food interactions on screening test of phenolphthalein with sodium hydroxide. I have done extensive searches on Medline,MELVYL at UCSF,GLADIS at UCB, LOIS at LANE(Stanford),and NML. I have the test procedure but not any info regarding known drugs or foods such as anthocyanin(fruits) that cause false positive or false negative test results. I am involved in a personal situation and any info or help would be greatly appreciated. I have a medical and chemical educational background and am not looking to tread on any one's research projects. I need the information strictly for personal use. Thank you again ahead of time. Thank you Sean sean@best.com .
