Antioxidant and antimutagenic activities of <i>Acacia pennatula</i> pods
859-864Methanolic extracts of Acacia pennatula pods (MEA) were
screened for antioxidant and antimutagenic properties by 1,1-
diphenyl-2-picrylhydrazyl (DPPH),
2,2´-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), ferric reducing
antioxidant
power (FRAP) and Kado microsuspension assays, respectively.
Total phenolic and flavonoid contents as well as HPLC identification
and quantification of gallic acid and (+)-catechin were also
carried out. MEA were capable of significant antioxidant
capacity by DPPH, ABTS and FRAP methods. MEA inhibited >
80% mutagenicity induced either by 4-nitro-O-phenylenediamine
or sodium azide. Thus phenolics-containing extracts of A.
pennatula pods display biological activities with potential
application in pharmaceutical and food sectors
β-Carotene Production under Greenhouse Conditions
β-carotene is a secondary metabolite that is a hydrocarbon carotene predominantly
located in lower concentrations in PS II functioning as a helper to harvest light pigment
during photosynthesis and to dissipate excess energy before damage occurs. As other
carotenes, β-carotene is uniquely synthesized in plants, algae, fungi and bacteria. βcarotene is the main diet precursor of pro-vitamin A. Additionally, β-carotene serves as
an essential nutrient and is in high demand in the market as a natural food colouring
agent, as an additive to cosmetics and also as a health food. Several approaches have
been carried out in order to increase β-carotene production in algae, bacteria, fungi and
plants using biotechnological and engineering focuses. In the case of plants, such species
as the tomato have important β-carotene contents, which are theoretically amenable to
management using approaches such as fertilization, growth conditions and mild stress.
On the other hand, greenhouse structures can protect crops from wind and rain, and can
also protect from insects when fitted with insect exclusion screens. β-carotene production
could potentially be improved and enhanced in greenhouse conditions in plants as well as in algae, based on the exclusion of the structure, and the possibility of controlling aspects
such as climate, fertilization and stress management, among others. Production of βcarotene (and other secondary metabolites) from several organisms in greenhouse
conditions should be an interesting future approach, visualizing the greenhouse as a
“factory” in frontier technologies such as biotechnology and mechatronics in order to
optimize this production
