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 ...

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.

Cold acclimation induced genes of trifoliate orange (Poncirus trifoliata)
Plant Cell Reports, 2004Commercial 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, 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 ...

Inhibition of immunoglobulin E production by Poncirus trifoliata fruit extract
Journal of Ethnopharmacology, 1999Immunoglobulin E (IgE) is the principal immunoglobulin involved in immediate hypersensitivities and chronic allergic diseases. The effect of an aqueous extract of Poncirus trifoliata (L) Raf. (Rutaceae) fruits (PTFE) on in vivo and in vitro IgE production was investigated.

Effects of Poncirus trifoliata on Type I Hypersensitivity Reaction
The American Journal of Chinese Medicine, 1997A study was carried out to examine the effect of an aqueous extract from immature fruit of Poncirus trifoliata L. (Rutaceae) (PTIFE) on the type I hypersensitivity reaction. Forty-eight hour PCA (passive cutaneous anaphylaxis) in rats was significantly inhibited by the oral administration of PTIFE (200 mg/kg).

Genetic Transformation of Poncirus trifoliata (Trifoliate Orange)
2000Poncirus is closely related to Citrus, and only one species, Poncirus trifoliata Raf. (Trifoliate orange), is recognized in this genus. This species is cultivated in China, Japan, Europe, and North America, and is sometimes used as a hedge, and the dried fruits as a medicine in China (Hodgson 1967).

Poncirus trifoliata fruit induces apoptosis in human promyelocytic leukemia cells
Clinica Chimica Acta, 2004Substances 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

Somatic Hybridization Between Citrus sinensis and Poncirus trifoliata
1994Citrus and Poncirus belong to the family Rutaceae. Citrus includes many commercially important fruit species such as sweet orange (C. sinensis), mandarin (C. reticulata), lemon (C. limon), grapefruit (C. paradisi), and is grown in over 100 countries in tropical and subtropical areas spreading over approximately 40° latitude. On the other hand, Poncirus
