Larvicidal constituents from Poncirus trifoliata root extracts

Journal of Medical Entomology, 2023
Abstract 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 ...

Antianaphylactic activity of Poncirus trifoliata fruit extract

Journal of Ethnopharmacology, 1996
The 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.

Cold acclimation induced genes of trifoliate orange (Poncirus trifoliata)

Plant Cell Reports, 2004
Commercial citrus varieties are sensitive to low temperature. Poncirus trifoliata is a close relative of Citrus species and has been widely used as a cold-hardy rootstock for citrus production in low-temperature environments. mRNA differential display-reverse transcription (DDRT)-PCR and quantitative relative-RT-PCR were used to study gene expression ...

Coumarins from unripe fruits of Poncirus trifoliata

Phytochemistry, 1977
Abstract 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 ...

Poncirus trifoliata fruit induces apoptosis in human promyelocytic leukemia cells

Clinica Chimica Acta, 2004
Substances inducing apoptosis have shown efficacy in the treatment of cancers. Poncirus trifoliata (L.) Raf. (Rutaceae) fruits (PTF) has been used for the treatment of various cancers among Korean Oriental Medical doctors.PTF-induced cytotoxicity of human leukemia HL-60 cells was monitored by the MTT assay. The apoptosis was determined by (a) apoptotic
