This is the second book in the series to cover structure elucidation of new natural products. It deals with the applications of modern spectroscopic techniques with particular reference to biologically important natural products including coumarinolignans, flavonoids, furanonaphthoquinones, antimalarials (e.g. artemisinin), quassinoids, triterpenes, isoquinoline alkaloids, indole alkaloids, insect pheromones, polysaccharides from fungi and lichens and marine natural products. Other areas covered are those involving studies of carcinogenicity of estrogens, lignans biosynthesis, oligo (N-methylpyrrolecarboxamide) antibiotics, polyketide antibiotics, antitumor, antifungal and herbicidal antibiotics, sterols, carotane sesquiterpenes, sesquiterpene quinones, prostaglandin synthetase inhibitors and avian hemoglobins. The authoritative articles from leading natural product chemists should provide a wealth of informative material for research work in this field.
