Abstract
“Che day” (Ampelopsis Cantoniensis Planch) popularly growing in the highland of Danang city, was known as medicinal plant by local people to treat deseases related to stomache and digestion. For helping local people to bring che day product into market, we determine physical, chemical norms and biological activities of “che day” product. The results show that the total sugar content in “che day” product was 99.19mg/g that make “che day” product having the sweet taste. The total flavonoid content was from 66% to 71% contributing the antioxidant and anti bacterial characters. In this research, we also conduct a process to grow and produce a good quality “che day” product in the condition of Biotechnology Lab – Dannang University of Science and Technology  for large batch production.
