The Cosmetic Potential of The Medicinal Halophyte Tamarix Gallica L. (Tamaricaceae) Growing in The Eastern Part of Algeria: Photoprotective and Antioxidant Activities

Abstract

Aim and Objective: Currently, the use of ingredients from natural sources has gained great attention in cosmetic field especially for the development of new photoprotective formulations. Therefore, the present study aimed to evaluate the cosmetic potential of the methanolic crude extract and the ethyl acetate fraction of the medicinal halophyte Tamarix gallica (Tg) growing in the area of Tebessa in eastern of Algeria, by assessing their phenolic and flavonoid contents, photoprotective and antioxidant activities. Methods: The research approach consisted of determination phenolic and flavonoid contents of aerial parts via FolinCiocalteu and aluminum chloride methods respectively. The antioxidant activity was measured through two in vitro methods DPPH radical scavenging activity and total antioxidant capacity test (TAC). The in vitro photoprotective effect was performed according to the parameter SPF (Sun Protection Factor) by using UV spectroscopic method in UV-B region (290-320 nm). Results: The methanolic extract (Tg-MeOH) and ethyl acetate (Tg-EtOAc) fraction showed good antioxidant activity with IC50’s 14,05±0,66, 27,58±1,98 µg/mL respectively in DPPH test. Furthermore, both extracts displayed strong total antioxidant capacity (287.01±7.85, 246.7±1.12 mg AAE/g, respectively) in TAC test. Both extracts exhibited high photoprotective activity, with sun protection factor (SPF) values 37.03±0.22 and 36.08±0.03. The antioxidant and photoprotective activities of these extracts is probably related to polyphenols content (190.27±0.74 mg AGE /g and 121.77±1.29 mg AGE /g, respectively) , and flavonoids (78.75±0.06 mg QE /g and 58.67±1.19mg/g). Conclusion: Our finding show that extracts of Tamarix gallica L could be a promising source to be mixed as natural sunscreens and antioxidants agent into photoprotective cosmetic formulations.

Highlighting the Cosmeceutical Potential of the Edible Bunium alpinum Waldst& Kit (Apiaceae) Growing in Algeria: in vitro Antioxidant and Photoprotective Effects

“…This is related with a previous report that demonstrated the significant photoprotective effect of flavonoids in UV-B and UV-A range [1]. The protective factor of Ba-BuOH fraction (SPF=14.70±0.11) is higher than that of Ba-MeOH crude extract (8.20±0.22), indeed the higher SPF (290-320) value of Ba-BuOH is probably linked to its phenol and flavonoid contents, which is correlate well with several authors who demonstrated that the photoprotective effect is mainly associated with the levels of phenolics and flavonoids in plant extracts [33][34][35][36][37][38]. [23].…”

Antigenotoxic properties of the halophyte Polygonum maritimum L. highlight its potential to mitigate oxidative stress-related damage

“…The remarkable antioxidant activity observed in our study seems to be a feature of halophytes, although typically not as strong as the one displayed by PME. Studies have reported relatively low IC 50 values in the DPPH scavenging assay for extracts of halophytes, such as the species Tamarix gallica L. (aerial parts methanol extract, IC 50 = 14.05 ± 0.66 µg/mL) 33 , Limonium delicatulum (methanol extracts of leaves and roots, IC 50 = 10.58 ± 0.18 µg/mL and IC 50 = 5.79 ± 0.05 µg/mL, respectively) 34 , and Arthrocnemum indicum (Willd.) Moq.…”

In vitro comparative evaluation of Tamarix gallica extracts for antioxidant and antidiabetic activity

“…On cell line, catalase and SOD activities also showed EthTg has the maximum antioxidant activity as compared to MthTg and AqTg. Recently, Lefahal et al 53 also revealed the antioxidant activity of methanol and ethyl acetate extracts of the Tamarix gallica in context of DPPH and TAC assay. Both extracts showed strong TAC (methanol = 287.01 ± 7.85, ethyl acetate = 246.7 ± 1.12 mg AAE/g) and DPPH (IC50 methanol = 14.05 ± 0.66, IC50 ethyl acetate = 27.58 ± 1.98 μg/mL) activity.…”

“…TFC also showed positive correlation with all antioxidant parameters (Table 3). Recently, Lefahal et al 53 demonstrated that antioxidant activity of Tamarix gallica extracts were possibly associated to polyphenols content and flavonoids. TPC and TFC correlation with antidiabetic activity indicated that if these contents were elevated, α-amylase ( R ² = 0.824 and R ² = 0.963 respectively) and α-glucosidase inhibitory activities ( R ² = 0.985 and R ² = 0.531, respectively) also be elevated.…”
