“…Polyphenolic content in plants and fruits have been extensively studied due to the good impact these substances has shown as a potential health benefits arising from their biological activity as hepatoprotective, antiinflammatory, antiviral, antimicrobial and antioxidant activities (Ambigaipalan, 2015;Carocho and Ferreira, 2013;Dias et al, 2016;Kaur Kala et al, 2016). From the 29 different compounds found on P. americana by-products, 23 of them were found in peels (227.9 mg/g of extract) and only 8 in kernels (72.5 mg/g of extract), this represent around 3-fold higher polyphenols content in peels, these results obtained proved to be consistent with the other reports (Kosińska et al, 2012;Rodríguez-Carpena et al,2011).…”

“…The peels and pulps of many fruits, including avocado, contain a large amount of antioxidants that are responsible for the plant defence system, against different types of stresses, such as temperature and light (Ghasemzadeh and Ghasemzadeh, 2011;Manach et al, 2004). They are also known to have effects against some human degenerative diseases (Ghasemzadeh and Ghasemzadeh, 2011;Kaur Kala et al, 2016; Table 1 Retention time (Rt), waveleghts of maximum absorption in visible region (λ max ), mass spectral data, tentative identification and quantification (mg/g of extract) of phenolic compounds in the P. americana by-products (peels and kernels).…”

A B S T R A C TAvocado (Persea americana Mill.) is a worldwide consumed fruit, with great interest for cosmetic and pharmaceutical industries; however, 30% of avocado fruits are bio-wastes (peels and kernels), converting them into a potential source of bioactive compounds, such as phenolic compounds. Therefore, the hydroethanolic extracts of peels and kernels of Persea america Mill. var. Hass were analysed regarding their individual phenolic profile by HPLC-DAD/ESI-MS and correlated with their antioxidant, antimicrobial and cytotoxic activities. Avocado byproducts presented a very distinct phenolic profile, presenting higher concentration in peels (227.9 mg/g of extract for total phenolic content), mainly in (epi)catechin derivatives (175 mg/g of extract), followed by chlorogenic derivatives (42.9 mg/g of extract). In this study hydrophilic and lipophilic antioxidant assays were performed together for the first time in P. americana by-products, and although kernels showed a great antioxidant potential (EC 50 values ranging from 18.1 to 276 μg/mL), peels presented the highest potential (EC 50 ranging from 11.7 to 152 μg/mL), mainly due to the presence of phenolic compounds, and an overall better performance in the antibacterial assays. Further studies needs to be conducted to better understand the correlation between the presence of phenolic compounds and bioactivities, however, the main objective is to implement these biocompounds in different products and industries, due to results obtained, P. americana peels could be a great alternative in the substitution of synthetic antioxidants.

“…Albano et al (2015) have also provided data related to the antioxidant activity of betalainic colorants. On the other hand, there is plethora of information related with the antioxidant effect and mechanisms of action of the phenolic compounds (Ambigaipalan, 2015;Carocho and Ferreira, 2013;Dias et al, 2016;Kaur Kala et al, 2016).…”

“…Scientists have lately reported multiple properties regarding to phenolic compounds as antioxidants endowed with anticancer, antiinflammatory, antimicrobial and antidiabetic activities (Dias et al, 2016;Kaur Kala et al, 2016). Among the most cited properties attributed to polyphenols it is the protective effect against damage of the human body caused by reactive oxygen, nitrogen and sulfur species (ROS, RNS and RSS, respectively) (Ambigaipalan, 2015;Carocho and Ferreira, 2013).…”

A B S T R A C TOpuntia spp. are a tropical and subtropical plant that provides both edible green steams and fruits; however, the processing of this fruits results in the accumulation of enormous amount of by-products that can be a source of bioactive and pigmented compounds. Herein, three cactus pear from the species Opuntia ficus-indica var. sanguigna (OS) and gialla (OG) and Opuntia engelmannii (OE) were fully characterized regarding their phenolic and betalain composition and correlated with their antioxidant and antimicrobial activities. The hydroethanolic extracts of OE gave the highest amount of phenolic compounds isorhamentin-O-(deoxyhexosyl-hexoside) and betacianins (betanin); however, no betaxanthins were identified in this sample. This sample also revealed the lowest EC 50 values in all the antioxidant activity assays. Regarding antimicrobial activity, the hydroethanolic extracts of all species revealed to be more active than ampicillin. The pivotal objective of this work was to focus on exploring by-product biocompounds and possible outputs, thus, we could suggest the use of these natural colorants with intrinsic antioxidant and antimicrobial activity, which would grant industries to produce cleaner label products with functional benefits.

“…Phenolics are the products of secondary metabolism and play an important role in the growth and reproduction of plants (Song et al, 2010). In addition, phenolics have the function of reducing the risk onset of several diseases, including cancer and neurodegenerative diseases (Kaur Kala et al, 2016). Cereals and vegetables are abundant in phenolics compounds.…”

Summary Vitamin C, phenolic and flavonoid contents along with enzymatic and antioxidant activities were determined in germinated mung bean (Vigna radiate). Elevated levels of vitamin C 72.31 ± 0.62 mg/100 g FW and flavonoid content 85.57 ± 0.59 mg CE/100 g FW were estimated for euphylla after 6 days of germination. Moreover, maximum peroxyl radical scavenging activity 645.4 ± 28.5 μmol ASA equiv./100 g FW was also determined in euphylla. However, seed coat has the highest content of phenolic content (568.4 ± 8.8 mg GAE/100 g FW), whereas cotyledon depicted the highest ascorbate oxidase and peroxidase activities (396.5 ± 4.0 and 548.4 ± 2.8 min−1 g−1 FW, respectively). These findings revealed that euphylla in mung bean sprouts is the most bioactive part with significant level of phytochemicals. Therefore, after germination of 6 days, euphylla is the main source of nutrition in mung bean sprouts.
