Liquid Chromatography for Separation and Quantitative Determination of Adrenergic Amines and Flavonoids from Poncirus trifoliatus Raf. Fruits at Different Stages of Growth

open access: yesChromatographia, 2005
The fruits of Poncirus trifoliatus Raf. (Rutaceae) have been used against allergic diseases for generations and still occupy an important place in traditional oriental medicine. They have also been used to treat gastric and duodenal ulcers.

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 ...

Identification and genomic distribution of gypsy like retrotransposons in Citrus and Poncirus

Theoretical and Applied Genetics, 2003
Transposable 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 ...

Comparative analysis on the distribution of heterochromatin in Citrus, Poncirus and Fortunella chromosomes

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.

Volatile profiles of flavedo, pulp and seeds in Poncirus trifoliata fruits

Journal of the Science of Food and Agriculture, 2014
AbstractBACKGROUNDPoncirus trifoliata, also known as trifoliate orange, is a tree native to China and Korea and widely used all over the world as a rootstock breeding material. In this study the differences among the volatile profiles of flavedo, pulp and seeds from two cultivars (var. trifoliata and var.

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 ...

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).

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.

Genetic Transformation of Poncirus trifoliata (Trifoliate Orange)

2000
Poncirus 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).
