  Panax Notoginseng,a traditional Chinese medicine,has been used for thousands of years to treat cerebrovascular diseases.Being one of the main ingredients of Panax notoginseng saponins (PNS),ginsenoside Rg1 (Rg1) (molecular weight =801) is a hydrophilic naturally occurring drug that is hardly transported across the blood-brain barrier.The distribution of PNS in brain is important for cerebrovascular disease.Therefore,developing a novel approaches enhancing the brain delivery of PNS are required for the treatment of cerebrovascular diseases.The nanoemulsion(NE) mediated Intranasal pathway can be an efficacious drug delivery system for brain-targeting delivery [1].
