Studies on Cytotoxic Constituents in Pericarps of Mallotus japonicus. Part III

Journal of Natural Products, 1988
Two new cytotoxic chromene derivatives, butyrylmallotochromene [10] and isobutyrylmallotochromene [11], were isolated from the pericarps of Mallotus japonicus. The new derivatives were identified as 5,7-dihydroxy-6-(2',4'-dihydroxy-3'-acetyl-5'-methyl-6'-methoxybenzyl)-8 - butyryl-2,2-dimethylchromene [10] and 5,7-dihydroxy-6-(2',4'-dihydroxy-3'-acetyl-

Glucosylation of salicylic acid by cell suspension cultures of Mallotus japonicus

Plant Cell Reports, 1990
Salicylic acid was converted into its O-glucoside when administered to cell suspension cultures of Mallotus japonicus. The efficiency of the glucosylation was highest in the cells grown in Linsmaier-Skoog medium containing 1 μM 2,4-dichlorophenoxy-acetic acid at any scale of culture (7 ml - 3 1).

ent-Labdane Diterpenes from the Stems of Mallotus japonicus

Journal of Natural Products, 2013
Eight new ent-labdane diterpenoids, mallonicusins A-H (1-8), were isolated from the stems of Mallotus japonicus. Their structures, including the absolute configurations, were determined by extensive analyses of spectroscopic data and the ECD spectra of the Pr(FOD)₃ complex of substrates in CCl₄. The absolute configuration of compound 1 was confirmed by

Antitumor-Promoting Activity of Mallotojaponin, a Major Constituent of Pericarps of Mallotus japonicus

Oncology, 2009
Mallotojaponm, a major constituent of the pericarps of Mallotus japonicus (Euphorbiaceae), inhibited the action of tumor promoter in vitro and in vivo; it inhibited tumor promoter-enhanced phospholipid metabolism in cultured cells, and also suppressed the promoting effect of 12-O-tetradecanoylphorbol-13-acetate on skin tumor formation in mice initiated

Cryo-scanning electron microscopy studies of pits in Pinus Wallichiana and Mallotus Japonicus

IAWA Journal, 2010
Pits of a softwood (Pinus wallichiana) and a hardwood (Mallotus japonicus) were studied by Cryo-scanning electron microscopy (Cryo-SEM). The samples were chemically untreated and fully hydrated during freezing. Tori of P. wallichiana were frequently aspirated.

Gallic acid esters of bergenin and norbergenin from Mallotus japonicus

Phytochemistry, 1990
Abstract Four new gallotannins, 3,4-di-O-, 4,11-di-O- and 3,4,11-tri-O-galloylbergenins and 4-O-galloylnorbergenin, have been isolated from the bark and leaves of Mallotus japonicus, and their structures elucidated on the basis of chemical and spectroscopic evidence.

Isolation and evaluation of the radical-scavenging activity of the antioxidants in the leaves of an edible plant, Mallotus japonicus

Food Chemistry, 2008
The antioxidative properties of a hot water extract of the leaves of Mallotus japonicus were evaluated. The extract had a high phenolic content and strong antioxidative activity, compared with green tea, rooibos tea, and red wine. Six phenolic compounds were isolated as antioxidative components by HPLC.

Glucosylation of isomeric hydroxybenzoic acids by cell suspension cultures of Mallotus japonicus

Phytochemistry, 1990
Abstract Cultured cells of Mallotus japonicus converted exogenous o -hydroxybenzoic acid into its O -glucoside after a lag period of 8 hr during which time the aglycone was taken up rapidly by the cells, partly excreted and then re-absorbed. The glucosylation of the aglycone into o - O -β- d -glucosylbenzoic acid began almost simultaneously with

Hepatoprotective effects of bergenin, a major constituent of Mallotus japonicus, on carbon tetrachloride-intoxicated rats

Journal of Ethnopharmacology, 2000
The hepatoprotective effects of bergenin, a major constituent of Mallotus japonicus, were evaluated against carbon tetrachloride (CCl(4))-induced liver damage in rats. Bergenin at a dose of 50, 100 or 200 mg/kg was administered orally once daily for successive 7 days and then a mixture of 0.5 ml/kg (ip) of CCl(4) in olive oil (1:1) was injected two ...

Induction and relaxation of extrafloral nectaries in response to simulated herbivory in young Mallotus japonicus plants

Journal of Plant Research, 2017
The disadvantage of induced defenses compared with constitutive defenses is the time during which a plant is vulnerable to herbivory before activation. There is obvious importance in determining the costs and benefits of induced defenses. Some plants produce extrafloral nectaries (EFNs), which attract ants that protect against herbivores, and induce ...
