About
Diospyros kaki, the Oriental persimmon, Chinese persimmon, Japanese persimmon, kaki persimmon, or Fuyu persimmon, is the most widely cultivated species of the genus Diospyros. Although its first botanical description was not published until 1780, D. kaki cultivation in China dates back more than 2000 years.
How to grow it
Diospyros kaki is grown worldwide, with 90 percent of the total in China, Japan and Korea. In East Asia the main harvest time is in the months of October and November. The trees lose their leaves by harvest time. Occasionally, the brightly colored fruit is left unharvested on the tree as a decorative effect.
Cultivation of this species at first spread through East Asia. Since the 19th century, Diospyros kaki partially replaced date-plum (Diospyros lotus, also known as Caucasian persimmon) in some countries in South Europe and West Asia, because of its bigger fruits than date-plum; cultivation in California began at that time.
Safety
Apart from tannins, triterpenoid compounds such as α-amyrin, uvaol, ursolic acid, 19α-hydroxy ursolic acid and 19 α,24-dihydroxy ursolic acid can be isolated from the leaves of D. kaki.
The high content of the carotenoids beta-cryptoxanthin, beta-carotene, and zeaxanthin, along with some lutein and alpha-carotene makes the fruit nutritionally valuable.
