What traditional systems uses this plant?
This plant, known as Diphylleia sinesica, has been utilized in Traditional Chinese Medicine for centuries to treat various ailments through its medicinal leaves and roots. Practitioners historically employed the plant to address issues related to inflammation and to promote better circulation within the body. Its chemical components were believed to provide therapeutic benefits for managing pain and supporting digestive health. Beyond its medicinal applications, local populations often integrated the plant into regional herbal practices to manage seasonal illnesses. These long-standing traditions highlight the plant's significant role in historical botanical knowledge.
According to a study published by "The Analyst", the plant Diphylleia sinensis is used as a Chinese medicinal plant for the extraction of podophyllotoxin. The optimal surfactant selected for this plant was 1-allyl-3-methylimidazolium tetrafluoroboraate ([amim][BF(4)]). Analysis of podophyllotoxin in the herb showed a linearity in the concentration range of 0.005-0.4 mg mL(-1) with a correlation coefficient between 0.9993 and 0.9996. The limits of detection were 2.05-2.58 μg mL(-1) and the inter-day stability RSDs were less than 5.8%. Using the ILs-MAE technique, recoveries for podophyllotoxin were in the range of 97.1-102% with all RSDs lower than 3.0%.

According to a study published by "The Analyst", the medicinal plant Diphylleia sinensis contains the compound podophyllotoxin. For the extraction of this compound from Diphylleia sinensis, the optimal surfactant was identified as 1-allyl-3-methylimidazolium tetrafluoroboraate ([amim][BF(4)]). The analysis of podophyllotoxin was conducted using reversed phase high performance liquid chromatography in a concentration range of 0.005-0.4 mg mL(-1) with a correlation coefficient between 0.9993 and 0.9996. The limits of detection (LODs) were 2.05-2.58 μg mL(-1) and the inter-day stability RSDs were less than 5.8%. Using the ILs-MAE technique, the recoveries for the extracted podophyllotoxin were in the range of 97.1-102% with all RSDs lower than 3.0%.
