The study was conducted to collect basic data for the development of various products using powder prepared from leaves of Aloe vera. Anthraquinones content was evaluated for leaf developmental stages, leaf parts and tissues, cutting direction and washing water temperature, and dry period. Anthraquinones content was increased in longer leaves than younger leaves when mixture-extracted without separating rind (outer tissue) and gel. Anthraquinones content with the different parts of leaf was not different in leaf rind, but was decreased in leaf gel as getting from top into base part. Anthraquinones content was declined in leaf segments transversely cut and washed than in those longitudinally cut and washed and was not different regardless of washing water temperature. Also, dry period at room temperature did not affect anthraquinones content for 7 days after harvesting and first-washing. The results indicate that leaf developmental stages, leaf parts and tissues, and cutting direction might be major factors affecting anthraquinones content in manufacture process of aloe powder.
