Review
Persimmon (Diospyros kaki L.) leaves: A review on traditional uses, phytochemistry and pharmacological properties
Abstract
Ethnopharmacological relevance
Persimmon (Diospyros kaki
L.) leaves, known as Shi Ye (in Chinese), have a long history as a
Chinese traditional medicine for the treatment of ischemia stroke,
angina, internal hemorrhage, hypertension, atherosclerosis and some
infectious diseases, etc. Additionally, persimmon leaves could be used
as healthy products, cosmetics and so on, which have become increasingly
popular in Asia, such as Japan, Korea and China etc.
Aim of the review
The
present paper reviewed the ethnopharmacology, phytochemistry,
analytical methods, biological activities and toxicology of persimmon
leaves in order to assess the ethnopharmacological use and to explore
therapeutic potentials and future opportunities for research.
Materials and methods
Information
on persimmon leaves were gathered via the Internet (using Google
Scholar, Baidu Scholar, Elsevier, ACS, Pudmed, Web of Science, CNKI and
EMBASE) and libraries. Additionally, information was also obtained from
some local books.
Results
Persimmon
leaves have played an important role in Chinese system of medicines.
The main compositions of persimmon leaves were flavonoids, terpenoids,
etc. Scientific studies on extracts and formulations revealed a wide
range of pharmacological activities, such as, antioxidative,
hypolipidemic, antidiabetic, antibacterial, hemostasis activities and
effects on cardiovascular system. Based on the pharmacological
activities, persimmon leaves were widely used in clinic including
treatment of cardiovascular disease, hemostasis, antibacterial,
anti-inflammatory and beauty treatment.
Conclusions
Persimmon
leaves probably have therapeutic potential in the prevention and
treatment for cerebral arteriosclerosis, diabetes, hypertension. It
showed significant neuroprotection against ischemia/reperfusion injury in vivo and in vitro.
Moreover, it can regulate immune function and inhibite inflammation.
Further investigations are needed to explore individual bioactive
compounds responsible for these pharmacological effects in vitro and in vivo
and the mode of actions. Further safety assessments and clinical trials
should be performed before it can be integrated into medicinal
practices.
