چکیده

Heptaldehyde-modified chitosan (heptyl-chitosan, CH-Hp) was investigated as adsorbent for chromatograhic separation of the flavonoids from A. moluccana. The amount of 2"-O-rhamnosylswertisin isolated (30.0 mg) was approx. twice as high as swertisin (17.5 mg). The improved surface hydrophobicity effected by the heptyl groups promoted the separation of flavonoids. From the results obtained, CH-Hp seems to be more suitable for separation of glycosylated flavonoids than other flavonoids. Thus, modified chitosan described here can be used for hydrophobic interaction chromatography as sucessfully illustrated with flavonoids.

Separation of C-glycoside flavonoids from Aleurites moluccana using chitin and full N-acetylated chitin.

This paper describes a comparative study using different chromatographic supports (fully N-acetylated chitin, chitin and silica gel) to separate the flavonoids swertisin and 2"-O-rhamnosylswertisin from Aleurites moluccana. The results show that the flavonoids have apparently been separated by the hydrogen bond between the stationary phase (chitin and chitin-100) and flavonoids under the condit...

Anti-inflammatory and antipyretic activity of aleuritis moluccana leaves

Aleurites moluccana (euphorbiaceae) has been extensively used in folk medicine for the treatment of ulcers, headache, fevers, diarrhea and hypocholesterolemia. Sterols, flavonoids and triterpenes have been isolated from the leaves of the plant. The methanolic extract of dried leaves of aleurites moluccana (AMME) was investigated for anti-inflammatory (carragenan induced rat paw oedema) and anti...

Aleurites moluccana (L.) Willd. Leaves: Mechanical Antinociceptive Properties of a Standardized Dried Extract and Its Chemical Markers

Seeking to develop a new analgesic phytomedicine, a spray-dried extract (SDE) of Aleurites moluccana (L.) Willd. leaves was developed in scale up (5 kg). The SDE was standardized at 3% w/w in relation to the flavonoid 2''-O-rhamnosylswertisin. The SDE batches were evaluated in relation to their physical, physiochemical, and pharmacological characteristics. The results demonstrated the reproduci...

Molecular cloning and expression analysis of a novel BCCP subunit gene from Aleurites moluccana.

Aleurites moluccana L. is grown as a roadside tree in southern China and the oil content of its seed is higher than other oil plants, such as Jatropha curcas and Camellia oleifera. A. moluccana is considered a promising energy plant because its seed oil could be used to produce biodiesel and bio-jet fuel. In addition, the bark, leaves, and kernels of A. moluccana have various medical and commer...

Separation of bioactive biflavonoids from Rheedia gardneriana using chitosan modified with benzaldehyde.

This paper shows the influence of benzenic groups on the chitosan surface for the separation of bioactive biflavonoids from Rheedia gardneriana leaves The yield of the biflavonoids using chitin modified with benzaldehyde (CH-Bz) as adsorbent in column chromatography was higher than that achieved with silica gel and chitosan. The presence of benzenic groups decreases the polarity of chitosan and...
