This book provides new information relating recent advances made in
the field of plant secondary products. Besides the updation of
chapters this edition also includes chapters on secondary
metabolites of microorganisms (fungi and lichen).
This book provides comprehensive and useful information on the
medicinal plants especially those used as food supplement in the
form of health vitalizers and invigorators. A subjective approach
is attempted for the first time in this book with all the
information available in one single volume. Separate chapters are
devoted to the medicinal values of each herb. The details about
various plant extracts possessing significant anti-stress activity,
are presented in this book.

The purpose of this book is to assess the potential effects of
biotechnological approaches particularly genetic modification on
biodiversity and the environment. All aspects of biodiversity such
as ecological diversity, species diversity and genetic diversity
are considered. Higher organisms contain a specific set of linear
DNA molecules called chromosomes and a complete set of chromosomes
in an organism comprises its genome. The collection of traits
displayed by any organism (phenotype) depends on the genes present
in its genome (genotype). The appearance of any specific trait also
will depend on many other factors, including whether the gene(s)
responsible for the trait is/are turned on (expressed) or off, the
specific cells within which the genes are expressed and how the
genes, their expression and the gene products interact with
environmental factors. The primary biotechnology which concerns us
is that of genetic manipulation, which has a direct impact on
biodiversity at the genetic level. By these manipulations, novel
genes or gene fragments can be introduced into organisms (creating
transgenics) or existing genes within an organism can be altered.
Transgenics are a major area of concern, combining genes from
different species to effectively create novel organisms. Current
rates of disappearance of biological and cultural diversity in the
world are unprecedented. Intensive resource exploitation due to
social and economic factors has led to the destruction, conversion
or degradation of ecosystems. Reversing these trends requires time
to time assessment to integrate conservation and development.
