Strong anti-inflammatory saponins Phytolacca americana (Phytolaccaceae) wereobtained from callus mass derived from the stems and also from that derived from the roots of cultivated Phytolacca americana (which were designated as PAS and PAR, respectively). The callus were grown on Linsmair and Skoog's agar medium supplemented with 1ppm OF 2, 4-dichlorophenoxyacetic acid. Phytol accoside B and D were obtained from PAS and phytolaccoside A and B from PAR. The thin layer chromatograms of the crude saponins from PAS and PAR were similar to those of original plants. PAS contained phytolaccoside B as a major component while phytolaccoside E was a major saponin in original plants.

Phytolaccaceae had been used as a pharmaceutical drugs or food in Korea. Nowadays, it is rarely used due to its toxicity, and then, case reports as to poisoning also are rare. Recently, Authors experienced a case of an occurrence in a group intoxication after ingestion of roots of phytolacca american a misidentifying as arrowroot. We report this case with review of phytolacca radix poisoning.

The triterpenoid isolated from the seeds of Phytolacca plants was confirmed to be acetylaleuritolic acid rather than acetylepialeuritolic acid by direct comparison with synthetic compounds.

Direct comparison of the triterpenoids isolated from the seeds of Phytolacca sp. and synthetic compounds confirmed that the natural products were acetylaleuritolic acid and 3-acetylmyricadiol rather than epiacetylaleuritolic acid, acetyloleanolic acid and phytolaccanol.

A glucoside mixture of ${\alpha}$-spinasterol and ${\delta}^7$-stigmastenol was isoated from the roots of Phytolacca esculenta $_{VAN}$ H$_{OUTTE}4. This the first reported occurrence of these glucosides in Phytolaccaceae family.

Phytolaccagenin, as a minor free terpenoid, was isolated from the roots of phytolacca esculenta van Houtte. A mixture of sterols was also isolated and identified as ${\alpha}$-spinasterol and ${\delta}^7$-stigmastenol, which never seemed to have been found in phytolaccaceae.

Americal A from the seeds of Phytolacca americana, was investigated for the antiinflammatory activity. The compound significantly inhibited edema induction, granuloma formation, arthritis induction and leucocyte emigration in CMC-pouch. But its anticarrageenin activity was not exhibited in adrenalectomized rats. These findings together with decrease in the contents of ascorbic acid and cholesterol in adrenals by administration of the compound suggest that its activity is mediated through stimulation of the pituitary-adrenal axis. The acute toxicity of the compound is very weak and gastric ulceration was not produced by the compound.

The purpose of this study is to review the taxonomical position of Phytolacca insularis Nakai based on morphological characters and ITS sequences. Phytolacca insularis was similar to P. acinosa in the stem shape, inflorescence, apocarpous, eight pistils, eight stamens, pink anther, and eight fruits. But the unique difference between P. insularis and P. acinosa was leaf size and pistil color. Phytolaccri insularis and P. acinosa have a similar sculpturing patterns as an foveolate and microscabrate in pollen, but they differed from P. americana in having a bigger foveolae size in sculpture pattern. Phytolacca insularis and P. acinosa were similar in the seed size but different from P. americana by having a small size of seed. The seed surface of P. insularis and P. acinosa was similar with a irregularly undulate shape, but its feature of P. americana differed in having the reticulate shape. Phytolacc a insularis had identical ITS sequences with P. acinosa. Phytolacca insularis and P. acinosa have a close relationship in the morphological characters and ITS sequences. The examinations of morphology and ITS sequences suggest that P. insularis be a form of P. acinosa although it has been formerly treated as a distinct species.

Cellular death by apoptosis is an active process, depending on gene transcription and protein synthesis. It was reported that nitric oxide can induce apoptosis in several cancer cell-lines. We studied effects of Phytolacca esculentum van Houtt (Phytolaccaceae) Radix water extract (PRE) on the proliferation of transplanted-L1210 cells in mice. When PRE (500 mg/kg) was administered orally once a day for 7 days after transplantation of L1210 cells to mice, DNA fragmentation of transplanted-L1210 cells was induced and mitochondrial transmembrane potential of those cells was reduced. Additionally, DNA fragmentation of L1210 cells was induced by the treatment of PRE in vitro. Also, DNA fragmentation of L1210 cells was enhanced by co-culture with the peritoneal macrophages obtained from PRE-administered mice and was partly inhibited by L-NMMA in vitro. PRE enhanced the production of nitric oxide and tumor necrosis factor-α from peritoneal rnacrophages. These results suggest that PRE induces apoptosis of transplanted-L1210 cells via directive action on L1210 cells and stimulation of nitric oxide and tumor neaosis factor-α from macrophages.
