Isoconiferoside, a new phenolic glucoside from seeds of Panax ginseng.

A new phenolic glucoside, isoconiferoside (1), was isolated from the seeds of Panax ginseng (Araliaceae). The structure was determined to be 9-O-[β-D-glucopyranosyl-(1 --> 6)-β-D-glucopyranosyl]-trans-coniferyl alcohol based on spectroscopic analyses (1H- and 13C-NMR, DEPT, COSY, HMQC, and HMBC) and acid hydrolysis.

Three new compounds, including a sesquiterpenoid glucoside gallate, 2 Z,4 E,1' R,2' S,4' R,6' S-dihydrophaseic acid 4'-O-(6''-O-galloyl)-β-D-glucopyranoside (1), two new phenolic glucoside gallates, 4-hydroxy-3,5-dimethoxybenzoic acid 4-O-(6'-O-galloyl)-β-D-glucopyranoside (2) and 3,4-dimethoxyphenol 1-O-(6'-O-galloyl)-β-D-glucopyranoside (3), together with eight known compounds (4-11), have be...

Lignin degradation: A microbial approach

Microbial Degradation of Asphalt.

Organisms of the genera Pseudomonas, Chromobacterium, and Bacillus capable of degrading asphalt were isolated by enrichment cultures. The asphalt degradation by these organisms varied from 3 to 25% after incubation for 1 week. The effects of temperature, pH, and atmosphere of incubation on asphalt degradation were investigated and were shown to vary with different organisms on the same substrate.
