PREFACE
Around 1950, a new era in natural products chemistry can be considered to have begun.
Aided by more and more effective techniques of separation, and increasingly useful spec-
troscopic methods, structures of natural products have been accumulating at an overwhelming
rate. This is certainly true of terpenoids, one of the most widely distributed and important
class of the so-called secondary metabolites. Terpenoids have singularly enriched organic
chemistry by its variety of structural types, by its wealth of 'unexpected' reactions, rear-
rangements and spectral features, and by offering exciting targets for synthesis. Much
imaginative experimental work has been invested in exploring their natural pathways. Recent
years have revealed an increasingly important biological and ecological role for several of
its members.
In view of these advances workers in this area have often felt a need for a sort of Handbook,
pinpointing salient features of known information, in a format which is at once accessible
and readable. The present work is in continuation of the effort in that direction.
A total of four sections covering the following categories are planned:
• Monoterpenoids
• Sesquiterpenoids
• Diterpenoids
• Triterpenoids
Steroids, carotenoids and certain classes of meroterpenoids (for example, indole alkaloids)
have been kept outside the purview of the present work. Each section will consist of two
or more volumes. Two volumes covering Monoterpenoids appeared in mid-1982. Four
volumes embracing Diterpenoids were published in 1985 to 1986.
The present work covers Triterpenoids in two volumes:
• Volume I: Acyclic, Monocyclic, Bicyclic, Tricyclic, and Tetracyclic
• Volume II: Pentacyclic, and Hexacyclic
Every effort has been made to cover naturally occurring compounds which have appeared
in accessible literature until the end of 1982. However, it will be unrealistic not to expect
errors and omissions in a work of this magnitude and the authors will be grateful to the
discerning readers for drawing their attention to these. Besides the Catalog Section which
forms the bulk of this work, a chapter entitled "General Introduction", which surveys the
development of triterpenoid chemistry, has been included. A selected list of references to
books, reviews, and key papers dealing with various aspects of triterpenoid chemistry has
also been added and should prove useful.
The authors would like to express their thanks to Shri. Arun P. Dindorkar for drawing
structures, to Shri. R. Kuttappan for typing almost all the manuscript, and to Shri. J. R.
Patel for checking the same. Finally, once again, I would like to thank Shashi Prabha, my
wife, for all the understanding and moral support which made the undertaking of this work
possible.

THE EDITOR
Sukh Dev was born in Chakwal, now in Pakistan, in 1923. He studied at Dayanand Anglo
Vedic College, Lahore (B.Sc. Hons., M.Sc.), and later at the Indian Institute of Science,
Bangalore (Ph.D., D.Sc.). He served as a Research Associate and Lecturer at the Indian
Institute of Science, and for one year (1957) as a Research Associate at the University of
Illinois, Urbana, before taking over as Head of the Division of Organic Chemistry (Natural
Products) at the National Chemical Laboratory, Poona, in 1960. In 1974, he moved to the
newly created Malti-Chem Research Centre as its Research Director. In 1989 he moved to
the Indian Institute of Technology, Delhi, as an INSA Research Professor.
Sukh Dev has been a Visiting Professor at the Stevens Institute of Technology, Hoboken
in 1968, at the University of Georgia, Athens in 1969, and at the University of Oklahoma,
Norman in 1970 to 1971. He has been an invited speaker at several International Symposia
and Seminars at many Universities/Research Institutes in several countries of the world. He
is the recipient of many National awards and in 1980 received the Ernest Guenther Award
of the American Chemical Society. He was elected President of the Indian Chemical Society
for the term 1978 to 1979. In 1987 he was elected President of the Organic Chemistry
Division Committee of the International Union of Pure & Applied Chemistry for the term
1987 to 1989.
His research interests include natural products chemistry, especially terpenoids and
Ayurvedic medicinal plants, azulenes and other nonbenzenoid aromatic systems, organic
synthesis, and new technology development. He has contributed over 270 research papers
and articles, and holds 48 patents. He is author of several books and book chapters.
THE AUTHORS
Amrit Sagar Gupta, born on November 1, 1925, had his early education at Lahore
(B.Sc., Hons, Panjab University, 1946) and received his M.Sc. (Hons) and Ph.D degrees
from Panjab University, Chandigarh.
Gupta joined the Natural Chemical Laboratory in October 1948 in the Division of Organic
Chemistry where he worked in various fields until the date of his retirement in October
1985. He has published more than 45 papers in national and international journals.
For 2 years (1966 to 1968), Gupta was Research Associate at the University of Illinois
Urbana, in the Laboratory of Professor N. J. Leonard. In 1982, he spent 6 weeks at the
Institute of Organic Chemistry and Biochemistry, Czechoslovak Academy of Science, Prague
under a bilateral exchange program.
His particular field of interest has been the chemistry of natural products.
Mrs. Sarita A. Patwardhan received her B.Sc. (Hons.) (1958), M.Sc. (1960) and Ph.D.
(1966) from Bombay University. She worked for her Ph.D at the National Chemical Lab-
oratory, Pune, India. Mrs. Patwardhan, at present, is working as a Senior Scientist in the
Division of Organic Chemistry in National Chemical Laboratory, Pune. She has published
over 30 research papers, review articles, and chapters. Her current research interests are
isolation of bio-active compounds from renewable resources, as well as their synthesis.
