Synopsis This detailed treatise is written for botanists, chemists and biologists as companion volume to "Glossary of Indian Medicinal Plants" by Chopra, Nayar & Chopra, and covers the ten-year period 1970-79. Volume 1 (1960-69) was published during February 1991. The format followed for Vol. 2 is similar to that of Vol. 1, i.e. the write-up on each plant also includes new type of data/information, viz. chemical structures of new compounds isolated and the biological work on pure constituents isolated from a plant. The first part of Vol. 2, like Vol. 1, presents the logistics of the write-up in an 'Explanatory Note', which is followed by the description of 1684 plants in 725 pages. Finally, three indexes (108 pages) comprising local names, chemical constituents and biological activities have been provided. The volume will be welcomed by all those working on medicinal plants/natural products who will appreciate that such a wealth of information has been assembled in a classified manner in a single volume. Volume 3, covering the ten-year period 1980-89 is under preparation.
