Lignin from candlenut shells was isolated using an ethanol-water accelerated solvent extraction method. Yields (based on Klason lignin) increased from about 14 to 33% as temperature increased from 100 to 195 °C and were also influenced by the amount of aqueous acid used to precipitate lignin from
This paper describes the preparation of chitosan modified with dialdehydes, glutaraldehyde (CH-Glu) and glyoxal (CH-Gly) and its application in the isolation of the flavonoids swertisin and 2"-O-rhamnosylswertisin from A. mollucana. The additional non-polar alkyl groups increase the hydrophobicity
In the present work we have investigated the analgesic activity of various extracts prepared from Aleurites moluccana leaves by using the writhing test in mice. The results showed that the hydroalcoholic extract and the hexane fraction exhibit potent antinociceptive action. We have also isolated and
