Chemical composition of the floral nectar of Peganum harmala, a herbaceous medicinal perennial of the family Zygophyllaceae, was analysed using high-performance liquid chromatography technique. The nectar sugar detection experiments resulted in 33.1, 39.8 and 27.4%, respectively, for fructose, glucose and sucrose, upon which the nectar was classified as hexose rich. In addition, 11 proteinaceous amino acids were recognised and quantified in the nectar. Concentration of the insects’ favoured… 

Anatomy and ultrastructure of the floral nectary in Peganum harmala L. (Nitrariaceae)

The abundant plastids and mitochondria suggest an eccrine mechanism of nectar secretion in Peganum harmala L. harmala, which appears to exude through the modified stomata along symplastic and apoplastic routes.

Content of Carbohydrates in Tropical Rainforest Nectars of Marantaceae Using High-Performance Thin-Layer Chromatography

The carbohydrate content of floral nectars of 12 Marantaceae species was analyzed by high-performance thin-layer chromatography (HPTLC). The main interest was not only to determine the sugar content

Main Alkaloids of Peganum harmala L. and Their Different Effects on Dicot and Monocot Crops

This study revealed that total alkaloids from seeds of the medicinal plant Peganum harmala L. harmala possessed significant growth inhibitory effect on four treated plants, with dicot plants being more sensitive than the tested monocot plants.

High-pressure liquid chromatography analyses of 73 plant species showed that the nectars of phrygana (East Mediterranean garrigue) mainly contain sucrose, glucose, and fructose, and traces of 10 minor sugars, confirming previous findings that Megachilidae have a key position in Mediterranean communities where they probably constitute a selective factor for “high sucrose” nectar.

Adaptive functions of defensive plant phenolics and a non‐linear bee response to nectar components

It is demonstrated that phenolic sugar syrups were attractants to free-flying Asian Apis cerana Fab.

What shapes amino acid and sugar composition in Mediterranean floral nectars

It is argued that due to the highly Concentrated nectars in the dry Mediterranean communities that are characterised by outstanding melittophily, sugars play a less important role as phagostimulants compared to AAs in floral nectar, and phenylalanine appears to be of high importance in phrygana.

In root cultures, the formation of β-carboline alkaloids can be induced by methyljasmonate and several other elicitors indicating that these alkaloid are part of the reactive chemical defence system of Peganum harmala.


The nectar of 889 species and some fifty varieties of Angiosperms has been analysed by paper partition chromatography and the types of nectar in some honey-bee flowers are explored.

Sugar Composition of Nectars and Fruits Consumed by Birds and Bats in the Tropics and Subtropics1

The proportions of glucose, fructose, and sucrose by paper chromatography in the nectar and fruit juice of 525 tropical and subtropical plant species were analyzed to test whether sugar chemistry was correlated with volant vertebrate pollinator or fruit disperser classes.

Intraspecific Constancy of Floral Nectar Amino Acid Complements

There is impressive constancy of the complements of nectars from a wide range of angiosperms on a "presence or absence" basis and considerable uniformity in the relative proportions of the amino acids represented.

The occurrence and significance of amino acids in floral nectar

It is reaffirm that the findings provide statistically significant data linking differences in the concentration with pollinator type and with life form and that high or low a.

A novel role for proline in plant floral nectars

An insect preference test found that honeybees indeed prefer nectars rich in the amino acid proline, demonstrating that plants often produce proline-rich floral nectar.
