Grundlagen des Derivatehandels, have been widely used by the natural products chemistry community. Inverse-detected heteronuclear shift correlation techniques are becoming recognized as a powerful adjunct to the COSY experiment and a replacement for their less sensitive and, in some cases, less versatile .C-detected predecessor experiments (Martin and Crouch 1991).

Assessment of Burley and Dark Tobacco Alkaloids During Storage, Aging, and Fermentation,ay be referred to as alkaloids because they occur naturally in green or processed tobacco, or they can be classified as “parent” alkaloids and their acylated, nitrosated, or oxidized derivatives. Structures of six representative tobacco alkaloids are shown in Fig. 1.

Book 1994C associated techniques. There have been many developments in the field of alkaloid analysis since the 1950s, not the least of which are the various powerful spectroscopic methods, which dominate this volume. Included also are the various aspects of tobacco alkaloids and analysis in various situatio

In addition, the addition of hormones to culture media, which is often necessary to encourage rapid root growth, can lead to the situation arising whe
