“…Many flavonoid rich plant and fruits from different species have been reported with antimicrobial activity (Balouiri et al, 2016;Melgar et al, 2017;Rodrigo and Martínez-l, 2015;Sansano et al, 2017;Šiler et al, 2014;Vieira et al, 2016b). P. americana by-products have shown great antibacterial and moderate antifungal activity against the strains tasted Table 3.…”

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.

“…High xanthone and flavonoid content resulted in significant anti-radical activity in C. erythraea extracts (Sefi et al 2011;Š iler et al 2014). This study provides the first assessment of TPC and ARA in different C. erythraea in vitro cultures with cell suspension culture exhibiting similar amount of TPC and significantly higher ARA than wild plants, even though in vitro shoot and callus cultures contained significantly lower TPC (Fig.…”

“…In addition, it also exhibits antioxidative, antibacterial, antifungal, anti-diabetic and diuretic activity (reviewed by European Medicines Agency 2016). Pharmacological properties have mainly been attributed to high content of secoiridoid glycosides, iridoids and xanthones (Andrade et al 1998;Aberham et al 2011;Piatczak et al 2011;Stefkov et al 2014;Š iler 2012;Š iler et al 2014).…”

Centaurium erythraea is medicinal plant with high content of secoiridoid glycosides and xanthones with gastroprotective, hepatoprotective and antioxidative properties. In vitro culture based C. erythraea production would offer sustainable and economically feasible alternative to wild plant harvest provided that comparable productivity could be achieved in artificially propagated plants. To identify most productive C. erythraea system the secoiridoid glycoside and xanthone production and profiles using liquid chromatography-mass spectrometry were assessed in in vitro shoot, callus and cell suspension culture-derived material in comparison with wild C. erythraea plants.In vitro shoot culture was the most productive system for C. erythraea secoiridoid production (total yield 86 mg g -1 dw) and cell culture was the most productive system for phenolic compound production (19 mg GAE g -1 dw). The effect of elicitors yeast extract, methyljasmonate (MeJA) and chitosan on secondary metabolite yield indicated that elicitation with MeJA and chitosan significantly decreased yield of sweroside and eustomin, respectively. Significant quantitative differences of major secoiridoids and xanthones indicated that further methodological improvements for increasing yield of major secondary metabolites of in vitro origin need to be explored for in vitro cultivation to become a feasible alternative to C. erythraea wild plant harvest.

“…Many scientific articles about Centaurium erythraea have confirmed its pharmacological activities as an antioxidant (Siler et al, 2014), antimicrobial (Kirbag et al, 2009;Siler et al, 2014), and antidiabetic (Hamza et al, 2010); and the correlation between these properties and its phytochemical composition including alkaloids (Sarker et al, 2001), essential oils (Jovanovic et al, 2009), coumarins (Valentao et al, 2003), triterpenes (Bellavista et al, 1974) and xanthone derivatives (Valentao et al, 2002).…”
