 About The Book  

   Newer techniques of isolation and analysis of plant derived chemical moieties have come up. Phytopharmacy has opened up new avenues for commercial exploitation. Quality Control and Quality Assurance hold the key to herbal drug technology.
   Knowledge related to establishment of profiles for qualitative and quantitative evaluation of crude drugs and their constituents is updated. Pharmacognosists focus on Systemic Pharmacognosy based on macro- and microscopic studies. An effort is made to include simple exercises on extraction and estimation of herbal constituents of pharmaceutical significance for strengthening laboratory work in pharmacy colleges and other institutions of biosciences. Around 30 exercises have been added to the original text of the book. Inclusion of text on “Frequently Asked Questions” will facilitate the students to preapre for Viva-voce examination. The list of reagents used and bibliography have been updated.
    The revised edition includes additional experiments on Thin-layer chromatography of cinchona alkaloids, and the estimation of capsaicin in fruits of Capsicum annum using HPLC technique and important references for the research students. Some of the diagrams have also been redrawn.
