Production of lepidimoide by an endophytic fungus from polysaccharide extracted from Abelmoschus sp.: identification of the product and the organism producing it
Journal of Bioscience and Bioengineering 93(6) (2002) 531-536
 

A highly potent allelopathic factor, lepidimoide, was initially extracted from mucilage of germinated cress seeds. Polysaccharide extracted from okra (Abelmoschus esculentum Moench) is considered to have a similar structure to lepidimoide as its repeating unit. We therefore initiated the screening of enzymes capable of degrading okra polysaccharide into lepidimoide from endophytes. We discovered an endophytic fungal strain AHU9748 isolated from Coleus galeatus, which produced an oligosaccharide having similar properties to lepidimoide on thin layer chromatography. The physico-chemical data from ESI-MS, NMR spectra and other analyses also showed the purified product to be identical to lepidimoide. The strain AHU9748 was identified as a fungus belonging to the coelomycetes, closely related to the genus Colletotrichum, based on morphological characteristics and sequence analysis of the 18S rDNA and ITS region

Carbon-13 nuclear magnetic resonance spectra of alditol-form oligosaccharides having the fundamental structural units of the Malvaceae plant mucilages and a related polysaccharide
Chemical and Pharmaceutical Bulletin 33 (1985) 5539-5542
 

The carbon-13 nuclear magnetic resonance spectra of five alditol-form oligosaccharides and a polysaccharide having the fundamental structural units of the Malvaceae plant mucilages were measured in aqueous solution and the signals were assigned.

Antidiabetic effect of compounds isolated from plants
Phytomedicine 5(1) (1998) 55-75
 

This review shows some of the compounds isolated and identified from the plants that previously demostrated a hypoglycemic effect. These compounds have been classified in appropiate chemical groups and data are reported on their pharmacological activity, mechanism of action, and other properties. This paper reviews mucilages, glycans, proteins, pectins, flavonoids, steroids and triterpenoids, alkaloids, other nitrogen compounds and miscellaneous substances with hypoglycemic effect.
