Evening Primrose (Oenothera biennis L.) is an industrial crop-producing seed with high oil concentration characterized by gamma-linoleic acid. However, limited information available on its response to the nutrient supply, especially P and K. The aim of this work was compare application N, P, K alone or in combination a deficient soil terms grain yield, yield components, composition comparison R...

The differences are reported in the triacylglycerol (TG) structures of oils containing gamma-linolenic acid (GLA) from Oenothera biennis Linn seed oil (OBLO) from the wild plant, evening primrose seed oil (EPO) from a cultured plant, and bio-GLA oil (BIO) from a mold, the physiological functions of which were ascertained by animal testing. Reverse-phase high-performance liquid chromatographic s...

Ellagitannins are bioactive plant polyphenols of which more than 500 individual compounds have been identified from plants. An ellagitannin-rich fraction was isolated by Sephadex LH-20 from Oenothera biennis (common evening primrose) leaves and roots and analysed by high-performance liquid chromatography/diode-array detection coupled to high-resolution mass spectrometry with an electrospray ion...
