Extracts of the roots of TINOSPORA CAPILLIPES Gagnep. (Menispertnaceae) afforded the quaternary protoberberine alkaloids palmatine, jatrorrhizine, columbamine, stepharanine and dehydrodiscretamine and the quaternary aporphine alkaloids menisperine and magnoflorine.
This study sought to determine the primary components (isoquinoline alkaloids, diterpenoids and steroids) in crude extracts of the Chinese herb Jin-Guo-Lan, prepared from the roots of Tinospora sagittata and T. capillipes, by liquid chromatography/electrospray ionization multistage mass spectrometry
Radix Tinosporae is a herb widely used in traditional Chinese medicine for the treatment of various inflammatory diseases. In the present study, its anti-inflammatory and antinociceptive activities were investigated. The ethanol extract of Radix Tinosporae exhibited significant inhibitory effects on
Quaternary alkaloids are the major alkaloids isolated from Tinospora species. A previous study pointed to the necessary presence of quaternary nitrogens for strong acetylcholinesterase (AChE) inhibitory activity in such alkaloids. Repeated column chromatography of the vine of Tinospora crispa
