Five new diprenylated flavonols from the leaves of Broussonetia kazinoki.[Pubmed:
11575957]
METHODS AND RESULTS:
Five new diprenylated flavonols, broussonol A (1), broussonol B (2), broussonol C (3), broussonol D (4), and Broussonol E (5), along with two known compounds, were isolated from an ethanolic extract of the leaves of Broussonetia kazinoki.
CONCLUSIONS:
Their structures were elucidated by chemical and spectral methods. Cytotoxic activities were evaluated against several different cell lines.

Chemical constituents from Engelhardtia roxburghiana.[Reference:
WebLink]
To study the chemical constituents from the stem bark of Engelhardtia roxburghiana.
METHODS AND RESULTS:
The compounds were isolated and purified by various chromatographic techniques and their structures were elucidated by spectral analysis. Ten compounds were obtained and identified as eudesm-4(15)-ene-1β,6α-diol (1), (4S)-4-hydroxy-1-tetralone (2), (-)-regiolone (3), p-hydroxybenzoic acid (4), kaempferol (5), isolicoflavonol (6), broussoflavonol F (7), Broussonol E (8), kaempferol-3-O-α-L-rhamnoside (9), quercetin-3-O-α-L-rhamnoside (10).
CONCLUSIONS:
Compounds 1, 4, 6–8 are isolated from the Engelhardtia plants for the first time, and the prenylated flavonoids are firstly reported in this genus.
