“…From this study, it was noticed that Young leaf extracts were richer in phenolic compounds than Mature ones. Similar results were previously reported by Habermann et al (2016) with the young and mature leaves of Blepharocalyx salicifolius.…”

“…However, because of the side effects of synthetic antioxidants on human health, the search for natural sources of antioxidants that can be used to delay oxidative stress in living organisms and prolong the shelf-life of foods has been deeply investigated (Womeni et al, 2016). In plants, the natural antioxidants are generally represented by phenolic compounds such as phenolic acids, flavonoids, anthocyanin, tannins, carotenoids etc (Habermann et al, 2016). Mangifera indica belongs to the family Anacardiaceae.…”

“…Though many studies have been reported on the phenolic content and antioxidant activity of Persea americana and Mangifera indica leaves, stem, fruits, flower and seeds, very few have been done on the evaluation of the phenolic content and antioxidant activity of their young and mature leaves, especially with the use of different extraction solvents and conditions. In one study, Habermann et al (2016) showed that the antioxidant activity and phenolic content of aqueous and ethyl acetate extract of young leaves of Blepharocalyx salicifolius were higher than those of the mature leaves. Similar observations were also made by Murugan (Murugan & Velayudhan, 2016) with the leaves of Tectona grandis.…”

Polyphenols are groups of secondary metabolites in plants, known with their various biological activities, including their ability to act as antioxidants. Due to the side effects of the use of synthetic antioxidants on human health, the search for natural less toxic compounds has significantly increased. This study was carried out to evaluate the phenolic content and antioxidant activity of young and mature avocado (Persea americana) and mango leaves (Mangifera indica). Different extracts were prepared by maceration in methanol, ethanol, cold and hot water. The phenolic content of the extracts was determined using the Folic-Ciocalteu Method. A total of three antioxidant tests were done on the extracts; the 2, 2-diphenyl-1picrylhydrazyl test (DPPH test), the Ferric reducing antioxidant power and the Hydroxyl radical scavenging activity. Results of these investigation showed that the mature mango leaves and young avocado leaves exhibited the highest phenolic and flavonoid contents. They were also very efficient as antioxidants in reducing the ferric ions and in scavenging the DPPH and hydroxyl radicals. Practical Applications Matured mango leaves and young avocado leaves are rich in polyphenols and have good antioxidant activity. They can be used as natural sources of antioxidants for the reduction of the damages caused by free radicals and reactive oxygen species in the body and some foods such as oils and foods containing lipids that easily oxidize.

“…We observed that C. spiralis leaves present more total phenols and a higher IC 50 in DPPH scavenging method than C. spiralis stems. A strong correlation between total phenolic content and antioxidant activity index has already been observed, with a correlation coefficient (r 2 ) of approximately 0.8 (Habermann et al 2016). Moreover, leaves commonly present more total phenols and antioxidant activity index than stems (Basma et al 2011, Mahdi-Pour et al 2012, Habermann et al 2016, Adebiyi et al 2017.…”

Costus spiralis is a Brazilian native plant used in popular medicine, but the safety of this therapeutic use needs investigation. So, the aim of this study was to evaluate the cytogenotoxic and antigenotoxic effects of C. spiralis leaves or stems aqueous extracts on Allium cepa root cells. Moreover, a phytochemical screening and an antioxidant and antifungal activities evaluation were performed. C. spiralis aqueous extracts presented cytotoxicity, but no mutagenicity was observed. When the antigenotoxicity was evaluated, C. spiralis leaves aqueous extract presented preventive and modulatory effects on A. cepa root cells, reducing the sodium azide cytogenotoxic effects. In contrast, C. spiralis stems aqueous extract enhanced the sodium azide cytogenotoxicity in some conditions. The phytochemical screening revealed the presence of phenolic compounds in C. spiralis. When total phenolic content was determined, the leaves presented 73% more phenolic content than stems. Corroborating this data, C. spiralis leaves antioxidant potential was 30% higher than C. spiralis stems. However, these extracts did not present antifungal activity against Candida spp. In conclusion, empirical utilization of C. spiralis aqueous extracts should be avoided. Moreover, the cytotoxic effect of C. spiralis leaves and stems can play an important role in anticancer therapy and must be deeply studied.

Gynura procumbens (Lour.) Merr. is traditionally used as a raw material for making dumplings or steamed stuffed buns, and its fresh leaves are boiled with water for tea. Herein, we established an ultra‐high–performance liquid chromatography–quadrupole time‐of‐flight mass spectrometry (UHPLC–Q‐TOF–MS/MS) combined with characteristic ion filtration (CIF) strategy to rapidly screen active ingredients with antioxidant and anti‐inflammatory properties in G. procumbens. This strategy involved screening the active part of G. procumbens using antioxidation and anti‐inflammatory activity assays; discovering the active compounds by speculating on the active site's chemical composition by UHPLC–Q‐TOF–MS/MS plus CIF; and verifying the active compounds' activities. The ethyl acetate extract (EEAF) of G. procumbens was the major active site. Eighty‐one compounds were identified from the EEAF using UHPLC–Q‐TOF–MS/MS plus CIF. Furthermore, polyphenols such as cynarine, isochlorogenic acids A and isochlorogenic acids C have excellent antioxidizing and anti‐inflammatory activities. This study provides a practical strategy for rapid in vitro screening of the antioxidizing and anti‐inflammatory activities of traditional vegetables and herbs and identification of active ingredients.
