Isolation and purification of penellic acid from Pinellia Ternata
Pinellia ternata is a perennial herb belonging to the Araceae family. Pinellia ternata is a plant native to Japan, but also grows as a weed in certain areas of North America. It is commonly used as one of the main components in many decoctions in traditional Chinese medicine that has been used wid...

Pinellia ternata is a perennial herb belonging to the Araceae family. Pinellia ternata is a plant native to Japan, but also grows as a weed in certain areas of North
America. It is commonly used as one of the main components in many decoctions in traditional Chinese medicine that has been used widely for thousands of years in China to prevent vomiting and for analgesic and sedative effects. Pinellia ternata is an active herbal component of the traditional Japanese herbal (Kampo) medicine, Sho-seiryu-to (SST) (Chinese name: Xiao-Qing-Long-Tang), and it has been reported to show oral adjuvant activity for nasally administered influenza hemagglutinin (HA) vaccine.
