Anti-bone resorption properties of the Korean herbal medicine, Yukmi-jihang-tang (YJ), which is comprised of seven herbs such as Rehmannia glutinosa Libosch, Dioscorea japonica THUNB, Cornus officinalis SIEB et. ZUCC, Smilax glabra ROXB, Paeonia suffruticosa ANDR, Alisma platago-aquatica var.

Tyrosine decarboxylase (TyrDC) is an important enzyme in the secondary metabolism of several plant species, and was hypothesized to play a key role in the biosynthesis of phenylethanoid glycosides. Based on the transcriptome data, we cloned the full-length cDNA (GenBank accession NO. KU640395) of

The protective effect of an iridoid catalpol extracted and purified from the traditional Chinese medicinal herb Rehmannia glutinosa on the neuronal degeneration of nigral-striatal dopaminergic pathway was studied in a chronic 1-methyl-4-phenyl-1,2,3,4-tetrahydropyridine (MPTP)/probenecid C57BL/6

Catalpol is an iridoid glycoside, distributed in the roots of Rehmannia glutinosa Libosch. In vitro results showed that preincubation with catalpol (0.5-0.5 mM) for 0.5 hours before and during 48 hour exposure to 0.2 mM MPP+ appeared to be significant protective effect while catalopl was

The endogenous neurotransmitter, noradrenaline, exerts anti-inflammatory and neuroprotective effects in vivo and in vitro. Reduced noradrenaline levels results in increased inflammation and neuronal damage. The primary source of noradrenaline in the central nervous system is tyrosine hydroxylase

The main objective of this study was to preliminarily determine the optimum formulation of a Chinese herbal formula that may have neuroprotective effects against rotenone-induced Parkinson's disease (PD). Seven recipes were made from Dihuang (DH, Rehmannia glutinosa Libosch), Roucongrong (RCR,
