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.

Seedlings of Poncirus trifoliata exhibit tissue-specific detoxification in response to NH4 + toxicity.

Plant biology
Ammonium nitrogen (NH4 + -N) is essential for fruit tree growth, but the impact of excess NH4 + -N from fertilizer on evergreen citrus trees is unclear.

Sortase A-Inhibitory Coumarins from the Folk Medicinal Plant Poncirus trifoliata.

Journal of Natural Products, 2020
Thirteen coumarins (1-13), including five new compounds (1-5), were isolated from the folk medicinal plant Poncirus trifoliata. Combined spectroscopic analyses revealed that coumarins 1-4 are bis-isoprenylated coumarins with diverse oxidation patterns ...

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 ...

Overexpression of PtrbHLH, a basic helix-loop-helix transcription factor from Poncirus trifoliata, confers enhanced cold tolerance in pummelo (Citrus grandis) by modulation of H2O2 level via regulating a CAT gene.

Tree Physiology, 2019
Basic helix-loop-helix (bHLH) family of transcription factors plays crucial role in regulating plant response to abiotic stress by targeting a large spectrum of stress-responsive genes.

Inhibition of immunoglobulin E production by Poncirus trifoliata fruit extract

Journal of Ethnopharmacology, 1999
Immunoglobulin 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, 1997
A 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).
