Chemical composition.—When the sowers of H. perforatum, 
_ freed from their calices and dried, are exhausted with absolute 
alcohol, and the tincture is evaporated, a soti residue is left of 
q a red colour (hypericum red) together with volatile oil. If 
_ the flowers are exhausted with water, then with dilute alcohol, 
well dried after exhaustion, and the colouring matter extracted 
from them by ether, it remains on evaporation as a blood- 
red resin, having an odour’ of chamomile. It melts below 
100° and does not yield ammonia by dry distillation. It is 
nsoluble in water and in dilute acids. By aqueons ammonia, 
‘potash and soda, it is coloured green and dissolyed ; the 
‘saturated solution is red by reflected light, but exhibits sittile 
ution a green colour by transmitted light. The ammoniacal 
olution leaves on evaporation a neutral blood-red resin 
ving the odour of hypericum, soluble with yellow colour in 
ter, and giving off ammonia when treated with potash. The 
combines also with the alkaline earths, earths proper, and 
eavy metallic oxides; its alcoholic solution precipitates the 
holic solution of chloride of calcium, also neutral acetate 
of lead and ferric chloride. It dissolves in alcohol, more 
dily in ether, with winc-red to blood-red colour, also in 
olatile oils and in warm fixed oils. ( Buchner.) According to 
arquart, the colouring matter of the fresh flowers is a mix- 
re of anthocyan and anthoxanthin, separable by exhausting 
alcohol and treating the residue with water,
