U. suzuki. Cane sugar in SEEtts. 



II. Seeds of Camellia theifera. 



The seeds were at first deprived of their shells. 600 grams 

 of these dried and powdered seeds were, after extraction with 

 petroleum ether, extracted with hot go% alcohol. The alcoholic 

 extract yielded on cooling a yellowish white precipitate which 

 was removed by filtration. The filtrate was now evaporated to 

 a syrupy consistency and then warmed with the addition of just 

 as much cf>% alcohol as was necessary to dissolve the whole 

 mass. After standing a few hours, crystals of cane sugar were 

 abundantly produced, which were recrystallized several times 

 from go% alcohol. Thus nearly 30 grams, or 5% of the dry 

 matter of the seeds, were obtained. 



As far as my knowledge goes, this is the first time that sucli 

 a high percentage of cane sugar has been found in seeds. Thus 

 E. Schuhe found in those of : 



Oats J gram from 3 kilo Earth nut 8.0 gram from 1 kilo. 



Rye 0.15 „ „ Yellow Lupine 4.0 „ 1.5 „ 



Tiuckwheat 3.5 ,, „ Sun flower 0.7 „ 500 gram. 



Coffee 2.5 „ 250 „ 



A high percentage, however, is also found in pollen, viz. 1 1-14% in that of the 

 pine and of the hazel nut (Planta).
