und helonin i-emaining behind, while Sabadillin and sabadillin- 

 liydrate are dissolved. — ^From the aqueous solution nearly the whole 

 of the Sabadillin crystallises in slightly reddish, concentrically 

 arranged, sexangular prisms, which become white by recrystallising. 

 It has an extremely acrid taste, fuses at 200°, losing 9 'öS % water, 

 is decomposed in higher temperatures ; dissolves little in cold, 

 readily in boiling water, also in alcohol, but crystallises not from 

 it; is insoluble in ether. It has a strongly alkaline reaction, and 

 forms with acids mostly crystallisable salts. 



jSiibsiililliii-lIydrate = C.o Hu NOe (=0.0 H13 NO5 + HO). 



By evaporating the liquid from which the sabadillin has crystal- 

 lised, oily drops are formed, congealing to a i-ed-brown, resin-like, 

 brittle substance. — Dissolves readily in water and in alcohol, not 

 in ether, is of alkaline reaction, forms with acids amorphous 

 salts. 



Na|J,'Jl|)eiUllll. (xum-resinous exudation of Ferula pei'sica and F. 

 Scovitziana. Yellow, brown, or reddish conglutinated grains of 

 garlic-odour and of acrid, bitter taste, softening with the warmth 

 of the hand. Contains two resins, gum, bassorin and volatile oil. — 

 One of the resins is red-yellow, ])ellucid, at first tough, smells 

 faintly garlic-like, tastes mild, afterwards bitter, dissolves readily 

 in alcohol and in ether, little in ammonia and in oils, partially in 

 potash-ley. The other resin is brown-yellow, brittle, inodorous and 

 tasteless, dissolves readily in alcohol and in warm potash-ley, not 

 in ether, ammonia and oils. 



SiTlicill=C26 Hig O14. Bitter glucosid of the bark, the leaves, 

 and other parts of species of Salix and Populus, probably also in 

 some species of Spiraea, which yield salicyloixs acid when distilled 

 with water. Boil the bark with water containing lime, clarify the 

 decoctions Avith albumen, strain, evaporate to a syrup consistence, 

 add pulverised charcoal, dry, extract with alcohol, distil the tinc- 

 ture and allow the remnant to crystallise. Becrystallise what has 

 formed in water with aid of animal charcoal. — Forms small, white, 

 shining needles and scales, is inodorous, of a very bitter taste 

 similar to willow-bark ; fuses at 198° without loss of weight, de- 

 composes in a stronger heat; dissolves in 22 parts cold and in half 

 part boiling water, in 30 parts cold and in three parts boiling 

 alcohol of 80 %, not in ether; has a neutral reaction; dissolves in 

 concentrated sulphuric acid with purple-red colour, and water pre- 

 cipitates a dark-red powder from the solution ; yields, on boiling 

 with diluted sulphuric acid, grape-sugar and a resinous substance 

 (saliretin zz Cu H e O2) ; on heating with the superoxyds of lead 

 and manganese, or with Chromate of potash and sulphuric acid, 

 formic and carbonic acids are produced, in the latter case associated 

 with salicylous acid. Metallic salts yield no precipitates.
