Quality of honeys from different botanical origins

Journal of Food Science and Technology, 2020
Botanical origin is one of the principal factors influencing the composition and quality of honey. This study aimed to evaluate different single-flower (assa-peixe, coffee, eucalyptus, laranjeira, and vassourinha), polyfloral (silvestre), extrafloral (sugarcane), and honeydew (bracatinga) honeys with regard to their chemical, physicochemical, and ...

Laxatives of Botanical Origin

1997
The principal anthraquinones are found in Rhamnus frangula and R. purshiana, Aloe ferox, A. barbadensis, A. succotrina, A. vera and A. africana. Rheum palmatum and R. officinale, Cassia acutifolia and C. angustifolia. The common name for the last group is Indian or African senna; these plants contain sennosides with anthranoid structures like those ...

The origin and rarity of botanical carnivory

Trends in Ecology & Evolution, 1987
Most plants are strict producers: they create the biomass consumed by animals and other heterotrophs to sustain life. Occasionally, the tables are turned and the plant becomes predator and the animal prey. Botanical carnivores remind us that some vascular plants have evolved remarkable mechanisms for acquiring key nutrients.

Botanical Origin of Tube-Curare

Nature, 1946
dextro-Tubocurarine chloride was first isolated in crystalline form from native tube-curare1. It has since become a valuable adjunct in anaesthesia2. The chemical constitution of dextro-tubocurine chloride and its relation to bebeerine3 suggests that its botanical origin lies in some species of Chondrodendron. Through the kindness of Mr. J. W.

Botanical origin of Indian celery seed (fruit)

Journal of Natural Medicines, 2009
In the course of our study on the traditional medicines and foodstuffs used in Pakistan, we investigated the origin of Indian celery by using the analysis of the internal transcribed spacer (ITS) sequence of nuclear rDNA and a phytochemical approach. We found that the source plant of the Indian celery containing coumarin derivatives such as seselin (1),

Neural networks applied to discriminate botanical origin of honeys

Food Chemistry, 2015
The aim of this work is develop a tool based on neural networks to predict the botanical origin of honeys using physical and chemical parameters. The managed database consists of 49 honey samples of 2 different classes: monofloral (almond, holm oak, sweet chestnut, eucalyptus, orange, rosemary, lavender, strawberry trees, thyme, heather, sunflower) and

Chemical Characterization and Botanical Origin of French Ambers

Journal of Natural Products, 2015
The molecular composition of 10 Cretaceous and one Eocene ambers from France was analyzed by infrared spectroscopy, solid-state (13)C nuclear magnetic resonance spectroscopy, and thermochemolysis gas chromatography-mass spectrometry. The terpenoids identified in the samples were used as biomarkers for the botanical origin of the resins.

Botanical Origin and Chemical Composition of Brazilian Propolis

Journal of Agricultural and Food Chemistry, 2002
Brazilian propolis has been classified into 12 groups based on physicochemical characteristics: five in the southern Brazil group (group 3), one in the southeastern Brazil group (group 12), and six in the northeastern Brazil group (group 6). The plant origins of these groups were investigated using reversed-phase high-performance thin-layer ...

Traceability Markers to the Botanical Origin in Olive Oils

Journal of Agricultural and Food Chemistry, 2009
This review provides an overview of traceability studies performed to date (April 2009) for olive oils. Special emphasis has been made on the botanical origin because high-quality monovarietal olive oils have been recently introduced on the markets and their quality control requires the development of new and powerful analytical tools as well as new ...

Mineral content and botanical origin of Spanish honeys

Talanta, 2005
Eleven elements (Zn, P, B, Mn, Mg, Cu, Ca, Ba, Sr, Na and K) were determined by inductively plasma coupled spectrometry in 40 honey samples from different places of Spain and four different botanical origins: Eucalyptus (Eucalyptus sp.), Heather (Erica sp.), Orange-blossom (Citrus sinensis) and Rosemary (Rosmarinus officinalis).
