V ALUATION OF POWDERE D 

 R HUBAR B. 



Tschirch recommends that 0.50 

 grammes of finely powdered rhubard are 

 extracted with 60 cc. of 0^ sulphuric 

 acid in a Soxhlet apparatus for 34 hour. 

 After cooling, and without first filtering, 

 the liquid is shaken with 50 cc. of 

 ether, and the ether layer separated. The 

 extraction with ether, in 50 cc. por- 

 tions, is continued until the ether re- 

 mains colorless, and does not become 

 colored red by addition of diluted solu- 

 tion of potassium hydroxide. The 

 aqueous liquid is now gently heated in 

 order to remove any traces of ether, and 

 is again extracted in a Landsiedl appa- 

 ratus for 15 minutes. The further extrac- 

 tion with portions of ether 50 cc. each is 

 continued, and the ether extracts are 

 finally united. 



The combined ether extracts are now 

 skaken out with 200 cc of 5^^ solu- 

 tion of potassium hydroxide, until the 

 aqueous extractions cease to show color. 

 The combined alkaline extracts are then 

 diluted with water to 500 cc. and 100 

 cc. of this solution is further diluted 

 to I liter with distilled water. Of the 

 latter solution 350 cc. are further 

 diluted to i liter with distilled water. 

 This solution when examined against a 

 white back-ground should still possess 

 a decided cherry-red color. This color 

 should be comparable with one obtained 

 by dissolving emodin i : 1,000,000 in dis- 

 tilled water and making alkaline. In this 

 manner samples of rhubarb containing 

 from 2.80 to 4% of Oxy-methyl anthra- 

 chinon may be recognized.
