Poncimarin, a New Coumarin from Poncirus trifoliata L.
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1975 Abstract A new coumarinic derivative (Poncimarin; C19H22O5; m.p. 140 °C) was isolated from unripe fruits of Poncirus trifoliata L. which from spectroscopic evidences was formulated as 7-(2,3-epoxy-3-methyl butyloxy)-8-(2,3-epoxy-3-me-thyl butyl) coumarin.

Antianaphylactic activity of Poncirus trifoliata fruit extract
Journal of Ethnopharmacology, 1996The effect of an aqueous extract of Poncirus trifoliata (L.) Raf. (Rutaceae) fruits (PTFE) on compound 48/80-induced mortality associated with anaphylaxis was studied in rats. PTFE inhibited compound 48/80-induced anaphylaxis 100% with a dose of 1.6 mg/g body weight (BW) 1 h before or 5 min after injection of compound 48/80.

Larvicidal constituents from Poncirus trifoliata root extracts
Journal of Medical Entomology, 2023Abstract In the search for effective and environmentally friendly mosquito control agents, we have examined natural sources, such as microbes and plants, and the synthetic analogs of natural products. These plants and microbes have evolved in their ecological niches to produce defensive compounds against other competing organisms in ...

Coumarins from unripe fruits of Poncirus trifoliata
Phytochemistry, 1977Abstract Petrol extracts of unripe fruits of Poncirus trifoliata L. were found to contain 7-geranyloxycoumarin, bergapten, imperatorin, 6-methoxy-7-geranyloxycoumarin and two new coumarins which were shown by chemical and spectroscopic means to be 7-(3′-methyl-2′,3′-epoxybutyloxy)-8-(3″-methyl-2″,3″-epoxybutyl)coumarin and 7-(3′-methyl-2′,3 ...

Identification and genomic distribution of gypsy like retrotransposons in Citrus and Poncirus
Theoretical and Applied Genetics, 2003Transposable elements might be importantly involved in citrus genetic instability and genome evolution. The presence of gypsy like retrotransposons, their heterogeneity and genomic distribution in Citrus and Poncirus, have been investigated. Eight clones containing part of the POL coding region of gypsy like retrotransposons have been isolated from a ...

Chromosome Research, 1997
Double fluorochrome staining with chromomycin A3 (CMA) and 4'-6-diamidino-2-phenylindole (DAPI) was used to characterize and compare the distribution of constitutive heterochromatin along chromosomes of Citrus, Poncirus and Fortunella species. Only CMA-positive bands were distinguishable in metaphase chromosomes.
