is changed into abietic acid, which latter is crystalline; 
other acids are also present, as pinic and sylvic ; ash 
about 1 per cent. 
Resin is not infrequently used as an adulterant of 
other resinous products, as of Burgundy pitch and 
Venice turpentine. 
KINO. 
The inspissated juice of Pterocarpus Marsupium, and 
probably other species of Pterocarjms (Fam. Legumi- 
noste), trees indigenous to Southern India and Ceylon. 
The juice is obtained from incisions made in the bark, 
and allowed to dry in the sun. The drug is exported 
from Madras and is known as Malabar or East Indian 
Kino. Kino is also obtained from Eucalyptus roslrata 
and other species of Eucalyptus (Fam. Myrtaceae), trees 
indigenous to New South Wales, this product being 
known as Australian Kino, Red Gum or Eucalyptus 
Gum. 
Description. — Malabar or East Indian Kino. — Small, 
angular, opaque, ruby -red, translucent, glistening, 
brittle pieces; inodorous; sweetish, very astringent and 
adhering to the teeth when chewed. 
Kino is entirely soluble in alcohol ; only partially 
soluble in cold water; not less than 80 per cent, should 
be soluble in boiling water. 
Australian Kino. — In masses or small fragments; dark 
reddish brown; somewhat dusty and tough. 
Constituents. — Tannin about 50 per cent ; kino red, 
and 2-6 per cent, of ash. Malabar kino contains in 
addition kinoin, a colorless crystalline principle appar- 
ently derived from the tannin. 
Allied Products. — The term kino is applied to 
various astringent plant juices which, while they con- 
tain large amounts of tannin, do not appear to be as 
valuable as either the Malabar or Australian kino.
