Bioactive glycosides from Chinese medicines

Area of Science:

• Pharmacognosy
• Natural Product Chemistry
• Medicinal Chemistry

Background:

• Glycosides are key bioactive constituents in numerous traditional Chinese medicines.
• Recent research has focused on isolating and characterizing novel glycosides from these sources.

Purpose of the Study:

• To report the discovery of various bioactive glycosides from Chinese medicinal plants.
• To highlight the therapeutic potential and drug development of these natural compounds.

Main Methods:

• Isolation and structural elucidation of glycosides from selected Chinese medicinal plants.
• Evaluation of the bioactivity of the identified glycosides.

Main Results:

• Discovery of three phenolic glycosides from Gastrodia elata, Aconitum austroyunanense, and Helicia erratica, with two developed into drugs.
• Identification of terpenoidal glycosides, including a monoterpenoid (sweroside) developed as an anti-hepatitis drug, diterpenoids, and triterpenoids from Panax species and Siraitia grosvenorii.
• Isolation of steroidal glycosides, such as C21-steroids with anti-epilepsy and anti-tumor activities from Cynanchum species, and C27-steroid hemostatic saponins from Paris polyphylla.

Conclusions:

• Chinese traditional medicines are rich sources of diverse bioactive glycosides.
• These natural compounds, including phenolic, terpenoidal, and steroidal glycosides, exhibit significant therapeutic potential.
• Several discovered glycosides have been successfully developed into pharmaceutical agents.
