ABSTRACT
This paper is a sequel of the first publication on the chemical constants/properties of 28 commonly used vegetable drugs in the Philippines. This paper reports on 36 additional vegetable drugs. The common, English/Spanish and scientific names, family and parts used and medicinal action of each plant are provided. Laboratory work includes the determination of moisture, total ash, acid insoluble ash, crude fiber, volatile oil and alcohol, dilute alcohol, hexane, water non-volatile ether and volatile ether extractives. Major findings include the presence of volatile oil in anis seeds, dalandan rind, langkauas leaves, lantana leaves, malunggai roots, oregano and yerba buena leaves and stems which are responsible for their major medicinal action and the large amount of total ash (23.3%) in campanilla leaves indicating the presence of plenty of inorganic salts. Plant samples with large amount of alcohol soluble extractives were cacao seeds, carrots roots, niog-niogan fruit, sampa-sampalukan whole plant and talong fruit indicating the presence of tannins, glycosides, saponins, resins and/or other alcohol soluble components.
INTRODUCTION
We have published Part 1 in the Philippine Journal of Science (Garcia et al. 1998) where we reported the chemical constants of 28 commonly used crude drugs in the Philippines. This paper reports on an additional 37 plants used as crude drugs. The constants include moisture, total ash, acid insoluble ash. . . .
