THE PHYSICO-CHEMICAL VALORATION OF TIKITIKI 



EXTRACT 1 



By Mariano V. del Rosario and Joaquin Maranon 

 Of the University of the Philippines 



For a long time this country has been paying very dearly for 

 exotic drugs. At present, however, there is the praiseworthy 

 tendency to utilize our own resources in the preparation of the 

 medicines used in combating the diseases peculiar to this part 

 of the world. 



The extract of tikitiki, 2 although recognized and prescribed for 

 a number of years, has not usually been prepared according to 

 any definite, standard method. Hence, differences in composi- 

 tion are found in the several brands that may be obtained in the 

 market; that is, the products show different proportions as to 

 their components. Consequently, we believe that our scientific 

 authorities should adopt an official method for the preparation 

 of this extract that would comply with established physical and 

 chemical principles. The compound that we are considering as 

 a standard is the one exemplified by the extract prepared by the 

 Bureau of Science, Manila, according to the method of Chamber- 

 lain and Vedder, 3 which is the one used in this laboratory. 



No definite conclusions leading to the formulation of a standard 

 extract of this drug can be drawn from the results obtained in 



1 From the laboratory of pharmaceutical chemistry, School of Pharmacy, 

 University of the Philippines. 



2 Tikitiki is the Philippine word meaning rice polishings.
