| Hazard Information | Back Directory | [Description]
An Alstonia alkaloid obtained from A. scholaris R. Br., this base also occurs in
Rauwolfia vornitora. It has [α]D - 47° (CHCI3). The ultraviolet spectrum in
neutral solution (EtOH) has absorption maxima at 237 and 287 mil, while in
acidic solution (perchloric acid), there are absorption maxima at 239, 244 and
305 mil. A methoxycarbonyl group, an alkyl group and an ether bridge are present
in the molecule. The picrate is obtained as light yellow crystals with m.p. 172-
4°C (dec.) and the methiodide has m.p. 235-7°C. | [Uses]
Picrinine is a monoterpenoid indole alkaloid extracted from Ochrosia elliptica, displaing the enhancement of immunomodulatory activity and apaptosis inducing in the A549 cell lines. | [Synthesis]
Lampstand leaves crushed into particles, take 10kg, with 15 times the amount of 1% sulfuric acid aqueous solution percolation extraction, the extract was filtered through the addition of molecular weight cut-off molecular weight 2000 hollow cellulose ultr | [IC 50]
