Iridoids from Gardenia jasminoides
The dichloromethane extract of the air-dried flowers of Gardenia jasminoides Ellis. afforded a new iridoid natural product (1), and a diastereomeric mixture of two new iridoids (2a and 2b) in a 2 : 1 ratio. Their structures were elucidated by extensive 1D and 2D NMR spectroscopy. Antimicrobial tests...

description | The dichloromethane extract of the air-dried flowers of Gardenia jasminoides Ellis. afforded a new iridoid natural product (1), and a diastereomeric mixture of two new iridoids (2a and 2b) in a 2 : 1 ratio. Their structures were elucidated by extensive 1D and 2D NMR spectroscopy. Antimicrobial tests on 1 indicated that it was moderately active against Candida albicans; slightly active against E. coli, Pseudomonas aeruginosa, Staphylococcus. aureus, and Trichophyton mentagrophytes; and inactive against Bacillus subtilis and Aspergillus niger. |
