78 Report of Schimmel § Co. 1921. 



ester v. 59.63 and 56; tiglinate 25.14 percent, and 23.60 percent; ester v. after acetyl. 

 208.65 and 220.27. Total alcohol (Ci H 18 O) 67.96 per cent, and' 77.1 per cent.; free alcohol 

 46.14 per cent, and 51.5 per cent. 



Two Bitter Almond Oils from Sevilla (containing prussic acid) and one from Valencia 

 (free of prussic acid) had the following properties:— Both were faintly-yellow, had the 

 characteristic smell and were optically-inactive: — d 23 c 1.045 and di 5o 1.0674; n D23 o 1.5419 

 and 1.5440; prussic acid 0.843 per cent, (by weight) or 0.862 per cent, (by volume); soluble 

 in any proportion in 90 per cent, alcohol and soluble in 0.5 vol. 80 per cent, alcohol 

 (both), and in 1.5 vol. and 1.4 vol. 70 per cent, alcohol. 



Four Fennel Oils 1 -) from Sevilla (of 1915), Cordoba (1912 and 1914) and Del Padul, 

 Granada (1916) had the following constants: — d|^ 0.8923 to 0.9212; a D20 o + 46°36' to 

 + 55°8'; n D20O 1.4842 to 1.5020; soluble in 0.3 to 1.0 vol. 90 per cent, alcohol, in 15 to 

 20 vol. 80 percent, alcohol; solidification point below — 10° and below — 13°; acid v. 



to 3.2; ester v. 3.2 to 16.9; fenchyl acetate 2 ) 1.99 to 5.92 per cent.; ester v. after acetyl. 

 1 7.3 to 46.0 ; total alcohol 4.76 to 1 2.65 per cent. ; free fenchyl alcohol 3.88 to 8.1 8 per cent. ; 

 anethole and estragol (methyl chavicol) 24.76 to 39.36 per cent; fenchone 15.04 to 

 20.69 per cent. These figures indicate that these products (at any rate the partly-bitter 

 fennel oils) do not correspond to the fennel oils of other countries. Dorronsoro 

 ascribes this fact to the circumstance that the manufacturers submit, not the fruit, 

 but the whole plant to distillation in order to secure a higher yield. 



The two oils from Cordoba yielded in a Ladenburg flask 7 fractions between 

 155 and 230° (705 mm.), of which the first ones had a very high specific rotation 

 («Di5o + 74°30 r and + 81°44'). From the fifth and sixth fractions (between 200 and 

 228°) the anethole separated at low temperatures and could thus be obtained. In the 

 sixth and seventh fractions, which were distinguished by a high specific gravity and 

 high refractive index, ethylfenchyl alcohol (inactive) was present. The substance is 

 not further identified in the memoir. 



A Master Wort Oil from Carcagente (Valencia) — the mother plants, Peucedanum 

 Ostruthium, Koch (Imperatoria romana; known under this name in Spain) and Peucedanum 

 Hispanicum, B., are frequent in the east and south of Spain — was a yellow, transparent 

 liquid of an agreeable sweetish odour reminding of pine leaf oil: — di 5 o 0.8611; a D + 44°56'; 

 n D15 o 1.4800; soluble in 5 vol. 90 per cent and in 22 vol. 80 per cent alcohol; acid v. 2.6; 

 ester v. 1 9.6 (corresponding to 6.93 per cent, of ester [Ci H 19 O • CO CH 3 ]) ; ester v. after acetyl. 

 44.21 (corresponding to 6.99 per cent, of free alcohol and to 12.74 per cent, of total alcohol). 



From Carcagente and Malaga originated two Eucalyptus Oils of the following 

 constants: — d 15 o 0.9300 and 0.9117; « D +1°38' and 4°14'; n D 1.4672 and 1.4662; soluble 

 in 90 per cent, alcohol and in 0.4 vol. 90 per cent, alcohol (turbidity with 2 vol.), in 



1 vol. and in 1.5 vol. (turbidity) 80 percent, alcohol, in 2.5 vol. and in 15 vol. (turbidity) 

 70 percent alcohol; acid v. 2.37 and 1.77; ester v. 15.82 and 13.66; cineole percentage 

 53 and 65.5 (resorcinol method). The distillation in a Ladenburg flask yielded the following 

 fractions: — 162 to 167°, 8. 17 per cent; 167 to 170°, 15.90 percent; 170 to 173°, 30.04 per cent; 

 173 to 180°, 11.92 percent; 180 to 183°, 14.00 per cent; residue 19.97 per cent. The high 

 residue percentage is striking. 



The following two oils of Peppermint came from Sevilla and Valencia; it is not 

 certain, however, whether they had been prepared from Spanish or from foreign 





a ) The constants suggest the presence, at least partly, of bitter fennel oils. — 2 ) It is not stated how 

 the fenchyl alcohol was identified; cZ,Z-fenchyIaIcohoI had so far been found only in American wood turpentine 

 oil; cf. Report April 1910, 108.
