Extracts of rosemary or hemerocallis fulva and methods of using same to promote circadian rhythm
Provided are process of regulating expression of one or more genes or proteins involved in circadian rhythm. A subject such as a cell is administered or contacted to an extract of rosemary, an extract of hemerocallis fulva , or combinations thereof, optionally provided as a component of a dietary supplement. The presence of one or more active agents in the extracts administered at a targeted administration time alters the expression of one or more genes or proteins involved in circadian rhythm, illustratively CLOCK, BMAL1, FBXL3, FBXL21, or SIRT1.
1. A process of altering an expression characteristic of a circadian locomotor output cycles kaput, brain and muscle Arnt-like protein-1, F-box/LRR-repeat protein 3, F-box/LRR-repeat protein 21, or silent mating type information regulation 2 homolog 1 protein in a human or animal in need thereof consisting essentially of:
administering to said human or animal in need thereof a therapeutically effective amount of an extract of rosemary and an extract of hemerocallis fulva at an administration time occurring at or between −4 hours to 12 hours after light exposure of the human or animal, wherein said therapeutically effective amount of the extract of rosemary and the extract of hemerocallis fulva consists essentially of ursolic acid at 10% or greater by weight.
2. The process of claim 1 said administration time is at or between 0 hours to 12 hours after light exposure.
3. The process of claim 1 said administration time is at or between 1 hours to 3 hours after light exposure or 10-12 hours after light exposure.
4. The process of claim 1 wherein said administration time is at or between −4 hours to 0 hours prior to light exposure.
