Guillaum, a traditional Vietnamese medicinal plant that has been used in the treatment of many dangerous diseases such as liver, lung, and cervical cancer. This study evaluated the influence of 5 types of packaging materials (PE, PA, PP, LDPE, HDPE) on physicochemical properties, bioactive compounds and antioxidant activity of fresh medicinal plant Xao tam phan during storage at room condition. The results showed that preservation of fresh Xao tam phan plant by PA packaging for 4 days at room condition achieved low resperation rate of -9.86 mL O 2 /kg/h, least weight loss of 0.40% and color difference of 8.27, maximum bioactive levels including total saponin content of 130.51 mg EE/g dry sample, total phenolic content of 10.20 mg GAE/g dry sample, and total flavonoid content of 169.36 mg CE/g dry sample, as well as greatest antioxidant activity comprising DPPH radical scavenging capacity of 4.18 mg TE/g dry sample, ferric reducing antioxidant power of 4.99 mg TE/g dry sample, and cupric reducing antioxidan capacity of 13.61 mg TE/g dry sample. Based on obtained results, PA packaging is proposed to preserve fresh Xao tam phan plant for further utilization and investigation.
