Tobacco leaves harvested from the bottom of Virginia tobacco plants contained the lowest amount of nicotine, whereas the leaves from the top contained the highest amount (37.37 and 60.4mg g dry tobacco, respectively) (Djordjevic et al. 1989).

Examination of the flavour constituents of the passion fruit Passiflora edulis has yielded the novel ionone derivatives (47) and (48). Edulans 1 and II, (49) and (50), and dihydroedulans I and II, (51) and (52), from the same source have been characterized fully. Two bicyclodamascenones, (53) and (54), have been identified as components of the flavour of Virginia tobacco, and several ionone, damascone, and cyclocitral derivatives are present amongst the many volatile compounds produced during flue-curing of this tobacco. ...

Nicotine belongs to the Solanaceae (nightshade family) alkaloids. It is the principal alkaloid of tobacco, but occurs also as a trace component in Acacia, Sedum, Erythroxylum, Equisetum and Lycopodium species. The two economically most important tobacco species are Nicotiana tabacum (Virginia tobacco), which grows up to 3 metres in height, has reddish flowers and lancet-shaped, pointed leaves, and the 1.2-metre high Nicotiana rustica species (known in South America as Mapacho and in Vietnam as Thuoc Lao), with greenish-yellow flowers and egg-shaped leaves (Fig. 5.204). 

For smoking, snuff, and chewing, Nicotiana tabacum is cultivated from the tropics to the temperate regions, correspondingto climate and soil requirements of a particular variety (e.g. Virginia tobacco. Oriental tobacco, Burley tobacco, Kentucky tobacco, Havana tobacco, Sumatran tobacco, Brazilian tobacco). The biggest producer by far is China, with Brazil, India and the USA as distant followers. Nicotiana rustica is produced in Poland, in Belarus, Ukraine, Kazakhstan and Russia, and also in the USA. 

Megastigma-5,8( )-dien-4-one (34) has been obtained from Virginia tobacco, from passion fruit, and, along with megastigma-5,7( ),9-trien-4-one (35), from Osmanthus absolute (an oil used in perfumery). The passion fruit, Pas-siflora edulis, has also afforded two other related compounds (36) and (37) and two further edulan derivatives (38) and (39). 

This rather low value bbtained at RJR s laboratories does not include nicotine nor similar bases. For the whole volatile material including bases, a value of at least 400 would seem reasonable. At Firmenich (Virginia tobacco), the steam-distillation of tobacco was carried out more exhaustively, affording better yield of volatiles.

The total content of alkaloids in tobacco ranges from 0.3 to 3% of dry matter, depending on the species and varieties of plants, climatic and soil conditions and other factors. Approximately 95% of this amount is represented by nicotine. For example, leaves of the so-called bright-leaf tobacco, commonly known as Virginia tobacco N. tabacum), with a total alkaloid content of 1.93%, containing 1.85% of nicotine, contains 0.04% of anatabine, 0.03%... 

Equally noteworthy were Tobias Crisp s mercantile family ties. For his father had been a London alderman while Tobias himself had married Mary, daughter of merchant Rowland Wilson the elder. His brother-in-law was Rowland Wilson, a freeman of the East India Company who was involved in the Spanish wine trade and whom Keith Lindley has identified as a leading City parliamentarian during the Civil War. Moreover, Tobias s widow would marry the Massachusetts Bay Company investor, Virginia tobacco trader and regicide Owen Rowe. All of which suggests that Jane s merchant brother may have had dealings with this powerful commercial network.
