Furostanol saponins vs steroidal saponins

A novel HPLC-UV method has been developed for the fingerprint analysis of the steroidal saponins in the rhizomes of three Ruscus species ( Ruscus aculeatus , Ruscus hypoglossum and Ruscus colchicus) . Saponins were identified by HPLC-ESI-MS. During the study a new major saponin was detected in the rhizomes of R. hypoglossum and R. colchicus . The structure of the new compound was defined as 1- O -[α- l -rhamnopyranosyl-(1→2)-6- O -acetyl-β- d -galactopyranosyl]-1β,3β,22ξ,26-tetrahydroxy-furost-5(6)- en -26- O -β- d -glucopyranoside ( 8 ) by spectral analysis.

Maple Syrup Urine Disease (MSUD) is a condition that results from improper metabolism of branched-chain amino acids. The aromatic in fenugreek, sotolon, may be used as a diagnostic criteria for MSUD as it exists in the urine of those persons with this metabolic defect and gives the characteristic sweet-scent. [14] It normally does not appear in healthy person's urine due to no dietary intake, but may appear in those who drink or consume fenugreek, leading to a false diagnosis. [90] Maternal consumption of sotolon can also transfer into the baby after birth, and cause trans-generational false diagnosis. [91]
