The seeds of Punica granatum, known as hap roman in the Arabian Peninsula, are commonly eaten as a dessert. As part of an ongoing project to find nonnutritional natural products which have health benefits, or that can be exploited to protect crops, the chloroform-soluble extract of the fermented seeds of P. granatum was found to be rich in 1-O-trans,cis,trans-9,11,13-octadecatrienoyl glycerol (1). The seed oil is not lethal to brine shrimp larvae. 1-O-isopentyl-3-O-octadec-2-enoyl glycerol (2) and the known cis-9-octadecenoic, octadecanoic, and eicosanoic acids were also detected in small amounts in the seed oil by LC and MS. The structure of 1 was determined from NMR and MS spectral data. 相似文献

This study describes the level of genetic variation and gene flow within and among populations of Prunus cerasoides in rehabilitated sites and adjacent intact forest. The seven microsatellite loci employed detected a total of 75 alleles
(n = 401). Polymorphic information content (PIC) varied from 0.34 to 0.83. Between the adult populations there was moderate genetic
differentiation with an F
ST value of 0.0575, which suggests that the restoration plots had a similar genetic composition to that of the natural population.
The gene flow assessment provides some interesting insights into the genetic diversity of P. cerasoides. In the 16 naturally occurring trees over 83% of the genotyped seed were fathered by unidentified trees whereas in restoration
plot A only about 32% of the pollen came from an unidentified father. This proportion was even less in Plot C where 25% of
the pollen parents were unidentified. The naturally occurring trees within Doi Suthep were surrounded by planted trees, which
were contributing to the paternity of the seed crop. This result demonstrates that ‘‘fill in’’ planting should consist of
locally sourced material if it is considered important to conserve the genetic integrity of the local populations. 相似文献
