Phytolacca japonica

There are few reports concerning the isolation of free histamine from higher plants. Among them, it was reported that from the dried roots of Phytolacca americana, as much as 1.3—1.6mg/g of histamine was present [3]. Histamine was not detected, or was detected as only a trace amount from extracts of the dried roots of Phytolacca esculenta and Phytolacca japonica. The dried roots of P. esculenta and/or P.japonica are used as the material for the crude drug Sho-riku in Chinese herbal medicine.Two out of four samples of marketed Sho-riku in Japan contained almost the same amount and about half the amount of histamine as that of P. americana, respectively. So it is considered that some of the marketed Sho-riku in Japan are prepared from the dried roots of P americana, or are increased in quantity with the root of P americana, which is naturalized widely in Japan and which possesses a larger root than those of P. esculenta and P.japonica.
