Background:: Lawsonia inermis Linn (Lythraceae), commonly known as "Henna" is a medicinal plant widely used as a folk remedy and for its cosmetic properties. Objective:: The objective of this present work was to evaluate biological activities and to quantify phenolics in extracts. Methods:: The extracts were obtained from seeds of L. inermis by increasing the polarity of the solvent. The content of total phenolics, flavonoids, flavonols and tannins was determined using colorimetric methods. Also, to evaluate the antioxidant activity, six different assays, DPPH, ABTS, superoxide radical scavenging, inhibition of β-carotene bleaching, ferric reducing antioxidant power and phenanthroline assays were used. Enzyme inhibition activity was evaluated by acetylcholinesterase, butyrylcholinesterase and tyrosinase inhibition assays. Furthermore, photoprotective activity was determined by measuring sun protection factor. Results:: The extraction efficiency of phenolics, as well as the biological activities of plant extracts, were affected by solvent polarity. The highest content of phenolics was determined in methanol extract (786.54 ± 0.00 mg GAEg-1 DW), followed by the aqueous and ethyl acetate extracts (526.48 ± 0.40 and 331.25 ± 0.00 GAEg-1 DW, respectively). The above extracts also exhibited the highest antioxidant activity, while low polar extracts were characterized with the lowest content of phenolics, as well as the lowest antioxidant capacity. The highest enzyme inhibition activities were found in ethyl acetate extract. Moreover, the methanol extract showed the best photoprotective activity with sun protection factor of 43.05 ± 0.37. Conclusion:: These findings suggest a possible use of Henna seeds as a potential source of bioactive molecules with antioxidant, enzyme inhibition and skin protection properties.

Background: Schinus molle L. is a medicinal and aromatic plant widely used in folk medicine commonly found in Algeria and Mediterranean region. In the present work, we investigated the in vitro antioxidant, anti-cholinesterase, αglucosidase inhibitory and photoprotective potentials of the Schinus molle L. plant’s extract/fractions. The metabolite profile of Schinus molle L. was analyzed using RP-HPLC and GC-MS. Methods: Antioxidant activity was assessed using different tests. Anticholinesterase activity was investigated by quantifying the acetylcholinesterase and butyrylcholinesterase inhibitory activities. Antidiabetic activity was investigated by αglucosidase inhibition test, whereas photoprotective activity was evaluated by sun protection factor (SPF) using spectrophotometry UV-Vis. The extracts were then submitted to RP-HPLC–PDA and GC–MS analysis. Results: Ethyl acetate and buthanol fractions with high contents of total phenolics and flavonoids exhibited the strongest antioxidant activity. Ethyl acetate extract exhibited considerable enzyme inhibition potential on acetylcholinesterase, butyrylcholinesterase and α-glucosidase with percentages of inhibition of 99.08 ± 0.79 %, 100 % and 98.80 ± 0.18 % respectively. Furthermore, the ethyl acetate fraction showed high photoprotective activity with the sun protection factor (SPF) value = 38,26 ± 0.73. Three phenolic acids (gallic, tannic and vanillic acids) and five flavonoids (myricetin, apigenin, naringenin, rutin and quercetin) were identified with RP-HPLC–PDA. Conclusion: These findings suggest that Schinus molle L. may be useful in the development of an alternative agent for oxidative stress, Alzheimer’s disease, diabetes and could be used as a natural sunscreen in pharmaceutics or cosmetic formulations.

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.

Sterculia populifolia is commonly used as the ingredient of traditional herb in Timor Island, East Nusa Tenggara, Indonesia. It contains flavonoid which roles as antioxidant. This flavonoid can be sunblock due to the existence of chromophore which commonly gives color to plants. This study aimed to determine the activity of antioxidants and sunblock through the value of Sun Protection Factor (SPF) from Sterculia populifolia extract-based cream and cream preparation extract. This cream was formulated into four formulas; extract concentrate 0% (F0), 1% (F1), 3% (F2) and 5% (F3). The result showed that the whole formula of cream preparation filled the physical stability parameter. F3 cream had IC50 79.179 ppm value while SPF had 5.6 value higher than F1 and F2. The smaller the IC50 value, the bigger antioxidant activity and SPF increased.

One way that is done to reduce the negative impact of sunlight is by using sunscreen. Sunscreen can protect the skin by spreading sunlight or absorbing sunlight radiation energy that is about the skin. Phenolic compounds especially flavonoid groups have the potential as a sunscreen because of the chromophore group (single conjugated double bond) capable of absorbing UV light both UV A and UV B, thus reducing the intensity of the skin. Flavonoids have three properties of photoprotektor that is UV absorption, antioxidant properties, and modulate some DNA signaling pathways. The potential of sunscreen can be expressed with Sun Protection Factor (SPF). SPF is designated as UV protection B and is not specifically intended to resist UV A and UV C. The purpose of this research is to know the value of SPF (Sun Protection Factor) of ethyl acetate extract of mango gedong leaves using UV-Vis spectrophotometry. Simplicia gedong mango leaves were extracted using ethyl acetate solvent by reflux. Gedong mango leaf extract identified flavonoid compound using 10% NaOH and H2SO4 (concentrated). Determination of SPF (Sun Protection Factor) value of med gedong leaf extract using UV-Vis spectrophotometry method. The concentration of ethyl acetate extract of mango gedong leaves used was 120 ppm, 240 ppm and 360 ppm. The SPF (Sun Protection Factor) values were analyzed using Mansur method. The result of identification of flavonoid compound showed that the extract of ethyl acetate of mango gedong leaves positively contain flavonoids, while the result of SPF (Sun Protection Factor) extract of ethyl acetate of mango gedong leaves was 5,556; 16,675 and 22,243. The SPF (Sun Protection Factor) extract of 5,556 muddy ethyl acetate leaves including moderate protection type, 16,675 and 22,243 including ultra-protection type when tested using UV-Vis spectrophotometry by Mansur method
