Description
The roots of Sternona japonica contain this complex alkaloid which forms colourless crystals from MeOH containing solvent of crystallization. The base is dextrorotatory with [α]D + 147.8° and the ultraviolet spectrum shows a broad absorption maximum at 305 m/J.. The picrolonate has been prepared as yellow needles, m.p. 237°C. The structure given above is based upon X-ray crystallo_x0002_graphic analysis of the MeOH solvate and on the already established configuration of Stemonine (q.v.).
Chemical Properties
White crystalline powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from Stemona bulbs.
Uses
Protostemonine is an alkaloid which provided protective effects of protostemonine in LPS/GalN-induced acute liver failure.
Definition
ChEBI: Protostemonine is an alkaloid. It has a role as a metabolite.
Synthesis
Tragacanth crushed into coarse powder (8.5 kg), with 8 times the amount of volume fraction of 90% ethanol heating reflux extraction 3 times, each time 1 h, combined with the extract, filtered. The filtrate was recovered to thick extract under reduced pressure, and the concentrated solution was dissolved with 1 times the amount of 1% hydrochloric acid, and the acid-water solution was centrifuged. Take the supernatant, alkalized with concentrated ammonia to pH 10, chloroform extraction for 3 times, concentrated under reduced pressure to obtain the crude extract of Morinda citrifolia (75 g). Take 10 g of the crude extract of Trachelium, dissolve with 4% hydrochloric acid 200 mL, filtered, the filtrate with ammonia to adjust the pH of 8 ~ 8.5, chloroform extraction, until the filtrate does not react with bismuth potassium iodide, decompression recovery of chloroform and the filtrate, drying, to get the total alkaloids 6.0 g. Take the total alkaloids of the above Trachelium through the Sephedex LH -20, rinsed with methanol, to remove pigmentation, collection of alkaloid-containing fractions, decompression recovery, and the total alkaloid-containing fractions. The fraction was collected and recovered under reduced pressure, and the solid was mixed with silica gel, loaded onto a silica gel H (200-300 mesh, 200 g) column, and eluted with a gradient of petroleum ether-acetone (3:1, 2:1, 1:1, pure acetone). After repeated forward chromatography, compound I was isolated as pale yellow crystals (650 mg), which was structurally identified as protostemonine (p rotostemonine).
