hemerocallis thunbergii/necrosis

BACKGROUND Hemerocallis citrina, a traditional herbal medicine, has been used for the improvement of behavioral and emotional status in Eastern-Asia countries. Previous studies in our laboratory demonstrated that ethanol extracts from Hemerocallis citrina (HCE) enhanced monoamines and brain-derived

The content of several phenolic acids and flavonoids in aqueous extract (AE) and ethanol extract (EE) of daylily flower (Hemerocallis fulva L.) was analyzed. The effects of AE or EE at 0.5%, 1%, or 2% in HUVE cells against high glucose-induced cell death, oxidative, and inflammatory damage were

Tumor necrosis factor-α (TNF-α)-induced reactive oxygen species (ROS) production in HepG2 was used to screen hepatocyte protective compounds from the flowers of Hemerocallis fulva. Three new polyphenols, n-butyl 4-trans-O-caffeoylquinate (1), kaempferol

Daylily (Hemerocallis sp.) plants declined in a homeowner's backyard in Walhalla, SC in June 2004. The backyard in northwestern South Carolina contained multiple, hardwood tree stumps, was surrounded by mature hardwood trees, and contained a dogwood tree showing symptoms of Armillaria root rot.

Foliar tissue samples of cultivated daylilies (Hemerocallis hybrids) showing the symptoms of a newly emergent foliar disease known as 'spring sickness' were investigated for associated fungi. The cause(s) of this disease remain obscure. We isolated repeatedly a fungal species which proved to be
