[资源] Pharmacognosy and Pharmacobiotechnology,Second Edition

Overwhelming appreciation, whole-hearted acceptance, and qualified success of the First Edition
of the textbook entitled ‘Pharmacognosy and Pharmacobiotechnology’ extended by the
postgraduate students specializing in Pharmacognosy and Phytochemistry, Biotechnology,
Pharmaceutical Chemistry, Chemistry of Natural Products; besides the enormous undergraduate
students in Bachelor of Pharmacy programmes in all the reputed Pharmacy Degree Colleges not
only in India but also abroad are quite encouraging.
Exclusively based upon the commendable comments and constructive criticisms received from
various academic colleagues across the country the author has meticulously presented this entirely
revised and duly expanded Second Edition. Moreover, the reading text material has been updated
thoroughly, various biosynthetic pathways modified adequately, chemical structures and tabular
contents enumerated more explicitly. Besides, the critical definitions, important statements,
terminologies, names of chemical constituents have been duly highlighted so as to facilitate its
readers to comprehend them accurately.
Tremendous achievement and advance in the different segments of highly sophisticated ‘Research
Techniques’ solely based on PC-modulated modern analytical techniques helped not only to clarify
the rather complex chemical structures of unravelled chemical constituents from Natural Products,
but also established precisely the plethora of ‘Biosynthetic Pathways’ dominating the plant kingdom.
The present textbook essentially comprises of nearly sixty ‘biosynthetic routes’ of predominantly
important natural chemical entities, such as: alkaloids, antibiotics, glycosides, marine-derived
drug substances, and terpenoids.
It is, however, pertinent to add here that certain extremely preliminary aspects to the related
pharmacognostical characteristic features of ‘Natural Plant Products’, namely: morphological
structures, adulterants used in herbal products, habitats, method of cultivation, geographical
distribution etc., have been expunged from the text, to which the students invariably obtain sufficient
exposure in the early stages of their systematic curriculum follow up.
The Second Edition essentially comprises of five additional chapters, namely:
(i) Nutraceuticals, (ii) Enzymes and Protein Drugs, (iii) Biomedicinals from Plant Tissue
Cultures, (iv) Hi-Tech Products from Plant Sources, and (v) Indian Traditional Herbal Drugs,
i.e., chapter-11 through chapter-15. The judicious and thoughtful inclusion of these five chapters
would certainly expose the PG/UG students of the aforesaid disciplines to an exceptionally solid
platform in the scientific pursuit of their knowledge.
The author feels convinced and earnestly believes that the Second Revised and Expanded
Edition of Pharmacognosy and Pharmacobiotechnology shall largely fulfil the much needed
value-added substantial text materials.
It is hoped that Pharmacognosy and Pharmacobiotechnology will continue to enjoy its
popularity amongst the august teaching fraternity, brilliant students, herbal practitioners,
pharmacognosists, herbal chemists, phytochemists, biotechnologists, and above all the researchers
who would like to make an illustrious career in their respective professional discipline in the New
Millennium.
Finally, the author wishes to place on record his deep sense of gratitude to Shri Saumya Gupta
M.D., and the entire professionals of New Age International (P) Limited Publishers, for their excellent
support to bring out this edition in such a short-span.
