Isolation and Structural Determination of Eriobofuran, A New Dibenzofuran Phytoalexin from Leaves of Loquat, Eriobotrya japonica L[Reference: WebLink]

METHODS AND RESULTS:
An antimicrobial substance, named as Eriobofuran (Ia) was isolated from loquat leaves [Eriobotrya japonica L. (Rosaceae)] inoculated with Entomosporium eriobotryae, a host-pathogenic fungus. The structure of Eriobofuran was deduced to be 2, 4-dimethoxy-3-hydroxy-dibenzofuran by spectroscopic, chemical evidence and biosynthetic considerations. Its structure was confirmed by direct comparison with a synthetic specimen of Eriobofuran ethyl ether.
CONCLUSIONS:
Eriobofuran inhibited strongly the spore germination and germ tube growth of Pestalotia funerea, a host-pathogenic fungus of loquat tree.

Chemical constituents from the fruits of Kadsura marmorata.[Pubmed: 22876677]

To study the chemical constituents from the fruits of Kadsura marmorata.
METHODS AND RESULTS:
The chemical constituents were isolated and purified by chromatography on silica gel, Sephadex LH-20 column and HPLC. 9 compounds were isolated and identified as 4,5-dihydroxy-3-methoxybiphenyl (I), Eriobofuran (II), 3beta, 16beta-dihydroxy urs-2-ene (III), 2alpha, 3beta, 6beta, 23-tetrahydroxy urs-12,18-dien-28-oic acid (IV), 2alpha,3beta,23-trihydroxy urs-12-en-28-oic acid (V), rutin (VI), 2-ethylhexanoic acid (VII), 2-monolaurin (VIII), glyceryl monoricinoleate (IX) on the basis of NMR and EI-MS spectroscopic analysis.
CONCLUSIONS:
All these compounds are isolated from this genus for the first time.
