... non-specific characteristics as well as testing the starch content of other fruit seeds. Result: The content of the extract is 12.5% water soluble, and the content of the extract is soluble in ethanol 1.5%. Based on the non-specific parameters of lai fruit seed starch, the water content was 11.4%, the ash content was 1.5%, and the acid insoluble ash content was 0.75%. The starch content test of lai fruit seeds was found to contain fructose. Conclusion: the seed starch of lai fruit has the potential to be used as an alternative to new excipients in pharmaceutical preparations.
