Constituents and quality criteria of Snake Jasmine

Summarised from the Snake Jasmine Root monograph of the Thai Herbal Pharmacopoeia, Department of Medical Sciences, the standard used to test the dried root.

The pharmacopoeia sets no minimum marker content for this herb. Use the raw material quality criteria below for acceptance testing.

Snake Jasmine Root contains naphthoquinones (e.g., rhinacanthin A, rhinacanthin B, and rhinacanthin C). It also contains triterpenoids, flavonoids, etc.

The THP monograph covers the root, while the formulas use the aerial part and whole plant, so the quality criteria on this page apply to the root only.
