As part of our ongoing search for bioactive constituents of natural Korean medicinal plants, three new lignan derivatives, sambucasinol A-C (1-3), together with 7 known compounds (4-10) were isolated from the twigs of Sambucus williamsii. The structures of these new compounds were determined by a combination of 1D and 2D NMR spectroscopic data analysis, as well as circular dichroism (CD) spectr...

The presence or absence of cyanogenic glycosides was determined for individuals from nine populations of Sambucus canadensis L. (elderberry) of east-central Illinois. In most of the populations tested, all or most of the individuals did not produce these compounds, in one, all were cyanogenic, whereas in another population this trait was highly variable. Addition of the enzyme emulsin to negati...

BACKGROUND Screening tools are proposed to identify those older cancer patients in need of geriatric assessment (GA) and multidisciplinary approach. We aimed to update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on the use of screening tools. MATERIALS AND METHODS SIOG composed a task group to review, interpret and discuss evidence on the use of screening tools...

WHY: Elder abuse and neglect is a serious and prevalent problem that is estimated to affect 700,000 to 1.2 million older adults annually in this country. Only one in ten cases of elder abuse and neglect are reported and there is a serious underreporting by clinical professionals, likely due to the lack of appropriate screening instruments. Abuse, neglect, exploitation and abandonment are action...

Three new lignans, sambucunol A (8) ((+)-erythro-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(4-hydroxy-3-methoxycinnamoyloxypropanyl)-2-hydroxyphenoxy]-1, 3-propanediol), sambucunol B (9) ((+)-threo-1-(4-hydroxyl-3-methoxyphenyl)-2-[4-(4-hydroxy-3-methoxy-cinnamoyloxy propanyl)-2-hydroxyphenoxy]-1, 3-propanediol) and buddlenol G (10) (2-{4-[2, 3-dihydro-3-hydroxymethyl-7-hydroxy-5-(4-hydroxy-3-methoxyc...
