Inner Structure. — See Figs. 252 ; 301, C. '*- ' 



Constituents. — Two crystalline pungent principles which 

 are found principally in the dissepiments of the fruit:- capsaicin, 

 which is slightly soluble in water and is volatile at 115° C, 

 forming irritating vapors ; and capsacutin, which is so powerful 

 that I part in 11,000,000 of water has a distinct pungent taste. 

 Capsicum also contains a volatile- alkaloid resembhng coniine; a 

 volatile oil with an odor of parsley ;. resin ; a small quantity of 

 starch ; a fixed oil, consisting of oleic, palmitic and stearic acids ; 

 and yields 4 to 6 per cent, of ash. 



Allied Drugs. — A capsicum of inferior quality known, as 

 Bom-bay pepper is obtained from plants growing in the vicinity 

 of the River Niger in Africa. The fruits are dull yellow or 

 brown in color, 2 to 3 cm. long and about 10 mm. in diameter.
