Phenols in Tobacco Leaves and Tobacco Smoke / Über die phenolischen Inhaltsstoffe des Tabaks und des Tabakrauches
Page range: 159 - 179
Abstract
This paper reviews
1.the plant phenols occurring in tobacco leaves, and 2.the phenols of tobacco smoke. These constituents are summarized in
2 tables. The leaf contains mainly quinic acid esters of hydroxy-cinnamic acids (chlorogenic acids), flavonol-glycosides, and hydroxy-coumarins. Main constituents are chlorogenic acid and rutin. Tobacco smoke does not contain these compounds, but a number of simpler phenols and phenol ethers, and phenolic acids. Besides this paper describes the transformation of plant phenols by the curing of tobacco, such as the formation of brown complex products from chlorogenic acid and rutin. Furthermore, the biosynthesis of plant phenols, their importance for the quality of tobacco, their phytopathological importance, and the effect of phenols occurring in tobacco leaves and tobacco smoke on the human organism are shortly reviewed

The Influence of Tobacco Moisture Content on the Composition of Mainstream Smoke Yield II / Einfluss des Feuchtigkeitsgehaltes von Cigaretten auf die Zusammensetzung des Rauches ll
Page range: 205 - 208
Abstract
The influence of tobacco moisture content on the yield of phenols in the mainstream smoke of a plain cigarette was studied. The yield of phenols calculated on the basis of dry weight of burnt tobacco decreases by 27 % over the range of moisture content adjustable by equilibrium.

Filling Capacity of Cut Tobacco. Method of Determination Developed by the „Centre d’Essais et Recherches Techniques du S.E.I.T.A.” / Die Füllfähigkeit von Schnittabak: Bestimmungsmethode des “Centre d'Essais et Recherches Techniques du S.E.I.T.A.”
Page range: 217 - 221
Abstract
The quantity of tobacco which is necessary for the correct filling of a cigarette depends on different factors and particularly on the filling weight (apparent density) of tobacco rag at a given pressure. Some years ago the ''Centre d'Essais'' of the SEITA developed an apparatus by which the filling weight being related to the filling capacity can be measured. The present paper describes the apparatus and its working conditions and deals with the causes of errors by which the measurements can be influenced.

The Statistic Apparatus Type 611 Developed by Güttinger and its Practical Meaning for Quality Control / Das Statistic-Gerät (Typ 611) der Firma Güttinger und seine praktische Bedeutung fuer die Qualitätskontrolle
Page range: 223 - 230
Abstract
The present paper reports on experiences gained, in practice, by the use of the statistic apparatus type 611 of the firm of Güttinger. By means of transmitting keys the transistorized calculating machine permits the determination of mean values and standard deviations of ten classes comprising 99 pieces each. It is demonstrated that several classes can combine and that piece numbers exceeding the mentioned limit can be adjusted by division without diminishing significantly the accuracy of the resulting values.
