Results and Discussion As part of our ongoing work on the characterization of natural products from food and medicinal plants aimed at rationalizing the molecular basis of laciniosq applications, the constituents of non-polar extracts of B. Table 1 Compounds identified from hexane extracts of leaves of B. Bromeliaceae Several recent severe regional droughts have led to increased interest in exploiting drought resistant edible plants as human food sources and as forage for domesticated animals.

After drying, the plant materials were powdered in a mill. Structures of non-polar compounds identified from the leaves of B. Antinociceptive effect of Encholirium spectabile: Efficacy and safety of plant stanols and sterols in the management of blood cholesterol levels. The volumes were reduced to mL B.

Bromelia laciniosa – Wikidata

This is the first thorough report on natural products from N. Conflicts of Interest The authors report no conflicts of interest. The efficiency with which alkanes might contribute to a cholesterol-lowering effect of waxes is regulated by limited absorption and the need for hydroxylation of these compounds.

However, their chemical compositions have previously not been determined. The nutritional value of E. Find articles by Ana Paula de Oliveira.

Extracts have exhibited no signs of toxicity towards mice [ 20 ]; have been reported to exhibit antioxidant [ 2122 ], photoprotective [ 22 ], and laciniosw activity in mice models [ 20 ]; gastroprotective activity in a mice model of gastric ulcer [ 23 ]; and antibacterial activity towards Gram-negative [ 1821 ] and Gram-positive bacteria [ 21 ].


The discovery of the presence of an active form of vitamin E in the crude extracts from B. New sources for known sapogenins. Strong fibers can also be extracted from Bromelia laciniosa ; the blades of the plant are cut, its thorns removed, its leaves fermented for several days to loosen up the fibers, and then its stalks are dried and readied for brojelia extraction; a caveat though is that this process gives off a pungent odor, so this task should be performed in a contained area.

In current literature, NMR spectroscopy has been successfully applied in the evaluation of metabolites of plant extracts NMR plant metabolomics [ 43 ].

The abundant starch, protein, fiber, and, especially, calcium content of Bromelia laciniosa makes it an attractive famine crop. Recent development in cryoprobe technology has led to a four-fold increase of sensitivity and thus a fold reduction of experiment time for 2D inverse experiments compared with those for similar NMR experiments recorded on analogous instruments equipped with conventional probes.

Journal List Molecules v. Altogether, 20 non-polar natural products were characterized. Like all bromeliads, the leaves of Bromelia laciniosa are covered with tiny scales that appear to be white and fuzzy; known as trichomes, these epidermal projections leaf hairs help the plant efficiently extract moisture from hot and dry climates.

Insights from an eight-locus plastid phylogeny. Notice that the characteristic signal patterns of the pure standard compounds matches the corresponding signals of the same compounds present as part of mixture comprising the extract of N. The isolation of some new cyclopropane-containing triterpenes from spanish moss Tillandsia usneoidesL. Dried and pulverized leaves of B. Abstract Extensive regional droughts are already a major problem on all inhabited continents and severe regional droughts are expected to become an increasing and extended problem in the future.


Stigmastanol is also known as sitostanol and is a phytosterol commonly found in many edible plants. An aqueous root extract may be drunk as a treatment against intestinal diseases and hepatitis, and as a diuretic [ 7 ]. In addition to pure samples of Aside for subsistence, Bromelia laciniosa can be sold on the market, whether for its flour or fibers or even its stalks to use for building material. Position specificity in n-hexane hydroxylation by two forms of cytochrome P in rat liver microsomes.

A Bromeliaceae from the Brazilian Caatinga biome.

Differentiation of refined and virgin edible oils by means of the trans – and cis -phytol isomer distribution. At the beginning of the bfomelia season, N.

While all seven were detected in N. Published online Sep 6. Overview of efficacy, effectiveness, and safety. For the first time, the non-polar constituents lacibiosa B.

Meanwhile, only the two longest n -alkanes, n -nonacosane C 29 and n -triacontane C 30were identified from the crude extracts from B. Compounds identified from hexane extracts of leaves of B. Samples were dissolved in hexane and splitless mode was used for injection.

Due to its biological traits, Bromelia laciniosa can propagate in climates with little moisture and low nutrient soils, which makes the plant an ideal crop for dry, semi-arid regions. Extensive regional droughts are already a major problem on all inhabited continents and severe regional droughts are expected to become an increasing and extended problem in the future.

Four fatty acids, palmitic acid, oleic acid, stearic acid and 9,12 -octadecadienoic acid, were identified from all three investigated species Figure 3.
