GC-MS determined distribution of urinary equol producers as affected by age, gender, and repeated ingestions of soymilk.

Status of equol excretion is likely a reflection of incidence risk of sex-hormone related diseases and deserves research attention. In this study, urine samples collected from 182 volunteers after soymilk ingestion were subjected to equol quantification using GC-MS. As categorized into male, female, and both genders and each category further classified into 6 age (year) categories, namely, <20, 21 to 30, 31 to 40, 41 to 50, >51 and overall, a trend indicating that the younger age the higher equol producer ratio was observed.

Structural identification and bioactivities of red-violet pigments present in Basella alba fruits.

Mature Basella alba L. fruit, with dark blue skin and deep red-violet flesh, is a potential source of natural colorants. Its pigment components and bioactivities deserve particular attention and investigation.
