Phenolic substances in Ailanthus glandulosa Desf

Phenolic Glycosides from the Twigs of Salix glandulosa.

As a part of an ongoing search for bioactive constituents from Korean medicinal plants, the phytochemical investigations of the twigs of Salix glandulosa afforded 12 new phenolic glycosides (1-12) and a known analogue (13). The structures of 1-13 were characterized by a combination of NMR methods ((1)H and (13)C NMR, (1)H-(1)H COSY, HMQC, and HMBC), chemical hydrolysis, and GC/MS. The absolute ...

Effect of Air Pollution on Carbohydrate and Nutrients Concentrations in Some Deciduous Tree Species

The concentrations of sugars, starch, nutrients and some heavy metals were examined during the growing season in four tree species (Ailanthus glandulosa DESF., Carpinus betulus L., Tilia argentea DESF. and Quercus cerris L.), growing in natural and planted stands in a region with considerable industrial emissions and in an unpolluted area. Trees in the polluted regions had lower concentrations ...

Phenylpropionamides, Piperidine, and Phenolic Derivatives from the Fruit of Ailanthus altissima.

Four novel compounds-two phenylpropionamides, one piperidine, and one phenolic derivatives-were isolated and identified from the fruit of a medicinal plant, Ailanthus altissima (Mill.) Swingle (Simaroubaceae), together with one known phenylpropionamide, 13 known phenols, and 10 flavonoids. The structures of the new compounds were elucidated as 2-hydroxy-N-[(2-O-β-d-glucopyranosyl)phenyl]propion...

Antiparasitic and antimicrobial indolizidines from the leaves of Prosopis glandulosa var. glandulosa.

A new indolizidine alkaloid, named Δ¹,⁶-juliprosopine (1), together with previously known indolizidine analogs (2- 6), was isolated from the leaves of Prosopis glandulosa var. glandulosa, collected from Nevada, USA; while two other known indolizidines, juliprosopine (6) and juliprosine (7), were isolated from P. glandulosa leaves collected in Texas, USA. The structures of compound 1 and 7 were ...
