Taro (Colocasia esculenta) is a food grade product that has a considerable amount of starch, which offers great versatility of applications at low cost. It can be used in different types of industries and has many applications. In this paper the starch extracted from C. esculenta was used with the purpose of evaluating its binding capacity as an alternative to be used in the preparation of solid pharmaceutical forms (tablets) in comparison with potato starch. The starches extracted from taro and potato were tested for identity: percentage of humidity, pH and particle size; as well as rheological tests: flow velocity, resting angle, bulk density, compacted density and Hausner index. Tablets with taro starch and potatoes were made, to measure its hardness, weight, diameter, thickness and disintegration time. To establish the differences between the groups of tablets (taro, potato and commercial acetylsalicylic acid -Aspirin- as control), an ANOVA and Tukey post hoc test were performed. It is concluded that the starch extracted from the C. esculenta flour can be used as an excipient in the manufacture of tablets. |
