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.

Purpose: To evaluate the correlation between sun protection factor (SPF) and the content of phenol and flavonoid and antioxidant activity. Methods: Different parts of 9 medicinal plants were extracted with methanol using three extraction methods (percolation, Soxhlet and ultrasonically assisted extraction) to obtain 42 crude extracts. Their phenol and flavonoid contents, and antioxidant activities were determined using Folin-Ciocalteu reagent, aluminum chloride method and DPPH radical-scavenging activity, respectively. The SPF values were determined and correlated with the phenol and flavonoid contents as well as antioxidant activities. Results: The phenol and flavonoid contents, and antioxidant activities ranged from 54.16-688.97mg GAE/g, 13.38-146.60 mg QE/g and 9.5-1472.4 µg/mL, respectively while the SPFs were between 0.067 and 0.841. The highest SPF was related to Cucumis melo L. ultrasonically assisted leaf extract (0.841) and Artemisia absinthium L., aerial parts extracted with percolation method (0.717). A significant correlation was found between SPF and phenolic (p= 0.003) and flavonoid contents (p= 0.023). Conclusion: This study showed a correlation between SPF and phenolic and flavonoid contents. Ultrasonically assisted extract of C. melo leaf has suitable SPF and can be used in sun screen formulations.

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.

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.

Objective: This study has investigated cosmeceutical properties namely, antibacterial, sun protection factor and total phenolics contents of some selected macrofungi. The studies were conducted on five reference cultures collected from Indian type culture collection center (IMTEC, Chandigarh, India) and five isolates collected from TERI-Deakin Nano Biotechnology Centre facility at TERI Gram, Gurugram, India. Methods: The cosmeceutical properties of the crude extracts from selected macrofungi were analyzed using standard bioassay techniques. Antibacterial activity was analyzed against Staphylococcus epidermidis, Escherichia coli, Micrococcus luteus, Bacillus megaterium, Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii using Agar well diffusion method. The sun protection factor was estimated and calculated using the Mansur equation. Free radical scavenging activity using DPPH was performed to assess the antioxidant activity of the extracts. Results: Ethyl acetate extracts of the broth from P. florida and TERI-G1 cultures showed a broad-spectrum antibacterial activity against S. epidermidis, E. coli, M. luteus and B. megaterium. Ethyl acetate extracts of the broth from TERI-G3 showed the highest SPF activity of 34.02 at 200 µg. ml-1 concentration. Ethyl acetate extract of the broth from F. velutipes, P. florida, P. ostreatus, and TERI-G1 showed comparable antioxidant activity of 66.86%, 79.51%, 82.02%, and 69.58% respectively when compared to ascorbic acid (85.83%) and quercetin (83.09%) taken as positive control in the study and their total phenolic contents were found to be 6.93, 43.68, 20.88 and 13.77 Gallic acid equivalent (GAE) per gram. The minimal inhibitory concentration of F. velutipes, P. florida, P. ostreatus, and TERI-G1 was found to be 3552.89 µg. ml-1, 1250 µg. ml-1, 2418.9 µg. ml-1 and 3219 µg. ml-1 respectively. Conclusion: The work is in progress to identify and characterize TERI-G1and TERI G3 cultures. Further studies on the anti-inflammatory, anti-tyrosinase, elastase inhibition properties of the cultures will be assessed to identify potential cosmeceutical active ingredients with promising applications in cosmeceutical products.
