background: this study has been undertaken to find out the possible radioprotective potential of the alstonia scholaris extract (ase). materials and methods: for experimental study, healthy swiss albino male mice were selected from an inbred colony and divided in four groups. group i (normal) did not receive any treatment. group ii was orally supplemented ase once daily at the dose of 100 mg/ k...

Recent work has shown that Alstonia scholaris has little or no antimalarial action on Plasmodia of birds (Goodson, Henry and Macfie, 1930 ; Buttle, cited by Sharp, 1934), monkeys and man (Mukerji, Ghosh and Siddons, 1942). These findings do not bear out those of earlier workers in the treatment of fevers believed to be of malarial origin. It was claimed that the alkaloids of Alstonia were more ...

2,3-Secofernane triterpenoids, alstonic acids A (1) and B (2), were isolated from the leaves of Alstonia scholaris together with an indole alkaloid, N(1)-methoxymethyl picrinine (3). Their structures were established from MS and NMR spectroscopic analyses and confirmed by single crystal X-ray diffraction analysis.

(1) Background: In China and South Asia, Alstonia scholaris (Apocynaceae) is an important medicinal plant that has been historically used in traditional ethnopharmacy to treat infectious diseases. Although various pharmacological activities have been reported, the anti-lung cancer components of A. scholaris have not yet been identified. The objective of this study is to evaluate the active comp...

Investigation into antimalaria activity of various fractions of Morinda lucida leaf extract and Alstonia boonei stem bark was conducted using standard techniques. The present study confirms the antimalarial activity of Morinda lucida and Alstonia boonei. Morinda lucida exhibited MIC of 0.6mg/ml and Alstonia boonei MIC 0.2mg/ml. The anti plasmodia activity of both plants were found to reside maj...

(1) BACKGROUND: Alstonia scholaris (Apocynaceae) is an important medicinal plant that has been historically used in "Dai" ethnopharmacy to treat infectious diseases in China. Although various pharmacological activities have been reported, the antimicrobial constitutes of A. scholaris have not yet been identified. The objective of this study is to evaluate the antibacterial constitutes from the ...

A total of 25 alkaloids were isolated from the leaf and stem-bark extracts of Alstonia spatulata, of which five are new alkaloids of the strychnan type (alstolucines A-E, 1-5) and the other, a new alkaloid of the secoangustilobine A type (alstolobine A, 6). The structures of these alkaloids were established using NMR and MS analysis and, in the case of alstolucine B (2), also confirmed by X-ray...
