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. Bromelia laciniosa Scientific classification Kingdom: Received Jun 30; Accepted Sep 2. Plant Systematics and Evolution. Overall, Bromelia laciniosa is a plant that is tailored for specific conditions and can be a valuable resource for a farmer.
Five of the seven triterpenoids have previously been identified from other species of the family Bromeliaceae Compounds 15 — Even though GC-HRMS is an excellent method for characterizing mixtures of natural products, there are some limitations in connection with the application of this method. With twice as many identified triterpenoids, N. Stigmastanol Compound 19 is previously known from two species of the Bromeliaceae family, namely A.

New sources for known sapogenins. Gastroprotective effect of an ethanolic extract from Neoglaziovia variegata arruda mez Bromeliaceae in rats and mice. 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.
National Center for Biotechnology InformationU. Associated Data Supplementary Materials moleculess Figure 1which belong to the subfamily Bromelioideae, and Encholirium spectabile Mart. Altogether, 20 non-polar natural products were characterized. The six n -alkanes identified in this work have a chain length ranging from C 25 to C The identifications were initially based on the fragmentation pattern observed in the mass spectra.
In addition to pure samples of Fatty acids and their derivatives. Fatty Acids and Their Derivatives Bromeloa fatty acids, palmitic acid, oleic acid, stearic acid and 9,12 -octadecadienoic acid, were identified from all three investigated species Figure 3.
Several drought-tolerant plants already utilized for such purposes belong to the Bromeliaceae and display features that make them especially capable of retaining water; the leaves are shaped adaxially concave to channel rainwater down to the overlapping, rosulate base for storage in a central cavity.
NMR plant metabolomics is, among others, a complementary strategy for identification of known plant metabolites of plant-derived extracts and allows for the detection of signals of all brokelia present in the sample lacinioosa sufficient quantities to be detected.
Macambira (Bromelia laciniosa)
The leaves of E. Samples were dissolved in hexane and splitless mode was used for injection.
Response of serum lipids bromepia lipoproteins of man to beta-sitosterol and safflower oil—A long term study. Soaking the seeds of Bromelia laciniosa in acetone for 60 minutes is an effective treatment that increases vigor and germination. This allows for applications of a broad selection of 2D NMR spectroscopic experiments, which are now accessible within an bro,elia time scale of approximately 15—30 min per experiment.
Bromeliaceae also have a Crassulacean acid metabolism CAM photosynthesis, where the stomata remain shut during daytime to avoid evaporation. Chemical characterization of lignin and lipophilic fractions from leaf fibers of curaua Ananas erectifolius J. Supplementary Materials Supplementary materials are available online.
As part of our ongoing work on the characterization of natural products from food and medicinal plants aimed at rationalizing the molecular basis of their applications, the constituents of non-polar extracts of B. Plant Material Leaves of B.
