These chemorational techniques have generated great interest in, and high expectations for, the acceleration of development of innovative pesticides. However, many purportedly successful appHcations of QSAR procedures have reHed on the quaHtative insights traditionally associated with art-based pesticide development programs. Retrospective QSAR analyses have, however, been helpful in identifying the best compounds for specific uses (17). Chemorational techniques have also found some appHcations in the development of pesticides from natural product lead compounds, the best known examples being the synthetic pyrethroid insecticides (19) modeled on the plant natural product, pyrethmm. 

Oleoresin. Natural oleoresins are exudates from plants, whereas prepared oleoresins are solvent extracts of botanicals, which contain oil (both volatile and, sometimes, fixed), and the resinous matter of the plant. Natural oleoresins are usually clear, viscous, and light-colored Hquids, whereas prepared oleoresins are heterogeneous masses of dark color. 

The held of marine natural products chemistry, which encompasses the study of the chemical structures and biological activities of secondary metabolites produced by marine plants, animals, and microorganisms, began in earnest in the early 1960s. " This is in stark contrast to the study of terrestrial plant natural... 

Provision for protection and safety equipment should be incorporated in the original plant design. The size of the plant, nature of the hazards, and the e.xposure will determine the amount, kind, and location of this equipment. 

Most of the occurrences mentioned above maybe related to the location of tlie plant. Natural hazards, waste disposal liazards, and avoidance of congested areas, particularly tliose with inadequate emergency facilities, may eliminate or minimize the potential hazards of the phuit itself. It is important to set an efficient and appropriate environment for the plant site, as was discussed in Chapter 5.

NGL are those portions of natural gas which are recovered as liquids in separators, field facilities or gas processing plants. Natural gas liquids include, but are not limited to, heavier hydrocarbon components, natural gasoline and condensate they may include small quantities of nonhydrocarbons.

A dietary supplement may be safe when taken in the recommended doses but may become dangerous in higher doses. However, patients may develop side effects even when ingesting recommended doses. Adverse reactions may be due to allergic reactions, dietary supplements containing toxic substances, mis-identification of plant, mislabeling of plant, natural toxic substances such as pyrrolizidine alkaloids in comfrey, unnatural toxic substances such as heavy metals, or pesticides.

The term "structural genomics" is used to describe how the primary sequence of amino acids in a protein relates to the function of that protein. Currently, the core of structural genomics is protein structure determination, primarily by X-ray crystallography, and the design of computer programs to predict protein fold structures for new proteins based on their amino acid sequences and structural principles derived from those proteins whose 3-dimensional structures have been determined. Plant natural product pathways are a unique source of information for the structural biologist in view of the almost endless catalytic diversity encountered in the various pathway enzymes, but based on a finite number of reaction types. Plants are combinatorial chemists par excellence, and understanding the principles that relate enzyme structure to function will open up unlimited possibilities for the... 

Understanding the molecular genetics of plant natural product pathways facilitates the engineering of these pathways for plant improvement and human benefit (see Chapter by Halkier et al). This chapter focuses attention on the need to start applying genomics technology to exotic species for development of biotech crops with novel natural products and with improved pest resistance and increased nutritional value.
