From the data analysis, the percentage area of three major compounds which is Trans-anethole, p-Anisaldehyde and Camphor are compared to the fresh sample analysis. The analysis due to both test show there are slight changes in the compound percentage area, which is less than 10% meaning that the changes are considered none. The samples from both tests maintain slightly the same properties as the fresh one.
