RESUMO

BACKGROUND: The aim of this study was to evaluate the moisturizing efficacy of quince fruit, used in folk medicine. For this purpose, the phytoconstituents of Cydonia oblonga fruit extract, like phenolics and flavonoids, were determined. A stable cosmetic emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and subjected to in vivo evaluation compared with a control. MATERIALS AND METHODS: Cydonia oblonga fresh fruit extract was evaluated for tyrosinase activity and phenolic and flavonoid content. A stable emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and tested in a skin irritation test. After this, in vivo tests of erythema, moisture, sebum, and skin elasticity were conducted. The in vivo evaluation was a randomized and single-blind study. Thirteen healthy female volunteers were selected for a three-month study period. RESULTS: Cydonia oblonga fruit extract showed good phenolic and flavonoid content, which was associated with its good antioxidant and tyrosinase-inhibiting activity. Cydonia oblonga containing the emulgel showed a reduction in sebum and erythema, while the elasticity and moisture content showed increments in their levels after the three-month application of the formulation. The fruit contains chlorogenic acid and many sugars, which might account for its anti-inflammatory and sebum reduction effects; it is also capable of enhancing the skin's hydration level and decreasing skin sagging by enhancing its elasticity. CONCLUSION: The emulgel loaded with Cydonia oblonga fresh fruit extract is verified regarding its folklore status as a moisturizing agent that enhances the facial skin cells' resilience potential.

RESUMO

BACKGROUND: Pharmacological properties of Quercus infectoria Olivier (galls) have been determined to be astringent, antidiabetic, antipyretic, anti-tremor, local anesthetic, and anti-parkinsonism. The galls of Quercus infectoria have been used for millennia in traditional oriental medicine in Asian nations to treat inflammatory illnesses. AIMS: The study's objective was to create a Quercus infectoria Olivier gall extract in stable water in oil (w/o) emulsion and to check its effects on the mechanical properties of skin and antiaging effects. METHOD: The galls were macerated in absolute methanol. Quercus infectoria Olivier gall extract's antioxidant property was evaluated using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) technique. Stearic acid, cetyl alcohol, KOH, glycerin, and distilled water were used to create the emulsion. The test (with extract) and control (without extract) emulsions were made, respectively, using the same process. Stability tests (color, liquefaction, microscopy, phase separation, and pH) are performed in in vitro, lasted 72 days at four distinct storage temperatures that is 8°C, 25°C, 40°C, and 40°C + 75% RH for both the control and test formulations. By using spectrophotometry, the (SPF) sun protection factors of the two formulations were calculated at various concentrations. Extract from Quercus infectoria underwent phytochemical investigation as well. RESULTS: The results showed that Quercus infectoria Olivier has antioxidant and (SPF) sun protection properties, reduce sebum, increases elasticity and stable emulsion containing 04% Quercus infectoria gall extract which might be used as topical antiaging formulation.

RESUMO

BACKGROUND: The potential as a depigmenting agent, sun protection, and healthy benefits is indicated by the sun protection factor, radical scavenging, and tyrosinase inhibitory activities of Alpinia galanga (wild). AIMS: A stable emulgel containing A .galanga (wild) extract is prepared. This emulgel is then characterized by in vitro evaluation and identification of contents by LC-ESI-MS2 . In vivo performance is counted in terms of moisturizing, melanin level, erythema, sebum, skin fine pores and large pores analysis, and other related physiological skin parameters. METHODS: DPPH radical scavenging activity, total phenolic and flavonoid counts were used to measure the free radical scavenging and tyrosinase inhibitory capability of A .galanga (wild) extract, respectively. LC-ESI-MS2 used for phytochemical analysis. Emulgels synthesize, and their globule size, Ultracentrifugation, pH, and conductivity were all evaluated. Among the developed formulations, the optimal emulgels formulation underwent 90-day stability tests for organoleptic characteristics and rheology at 8°C, 25°C, 40°C, and 40°C + 75% RH (relative humidity). Using sebumeter®, mexameter®, and corneometer®, changes in skin physiological parameters were assessed over the course of 12 weeks in 13 healthy male, Asian volunteers. VisioFace® is used for computational analysis of high-resolution pictures to determine the % area, fine pore counts, and large pore counts of the skin. RESULTS: The antioxidant, tyrosinase inhibitory potential and counts of total phenolic and flavonoids of A .galanga (wild) extract were impressive (85%, 75%, and 48.0 mg GAE/g and 14.37 mg quercetin/g, respectively). In terms of stability evaluation, globule size (0.7528 ± 0.192 µm). Optimized A .galanga (wild) ethanol aqueous (AGEA) extract loaded emulgel was stable in terms of organoleptic and in vitro evaluation. The AGEA formulation significantly reduced the amount of sebum, erythema, fine pore counts, large pore counts, fine pore % area and large pores area percentage while significantly improved the moisture and elasticity of the skin. CONCLUSION: A stable A .galanga (wild) extract loaded emulgel was successfully produced that improved the skin physiological parameters in terms of skin's sebum, erythema, moisturizing, melanin, and pores.

RESUMO

Current study was designed to determine the skin elasticity potential of tested emulgel formulations. One emulgel containing Pyrus communis fruit extract and the other had Cydonia oblonga fruit extract. For this purpose 26 female subjects were selected and divided into two batches. Each batch has 13 volunteers, who used tested formulations and their base for 90 days. Skin elasticity were observed by using Cutometer MPA 580. From Cutometer skin mechanical parameters were calculated. From the results it was noted that emulgel formulations containing extracts of Pyrus Communis and Cydonia oblonga showed marked effect on the facial skin mechanical properties during 90 days study period. Statistically observed skin mechanical parameters of tested formulations had significant difference from base. After distention from Cutometer both formulations enhance the retraction ability of the skin as compared to base. Moreover it was also noted that Cydonia oblonga had more pronounced results than Pyrus communis loaded emulgel. From the results it has been interpreted that although both formulations has good potential to hydrate the skin resulting in intensification of its elasticity. As both fruits are rich source of phytonutrients like Vitamin C, Sugar, organic acids which might be the reason of their enhancement potential of skin pliancy.

RESUMO

Duckweed (Lemna minor L.) is an aquatic macrophyte and grows profoundly on the surface of polluted water reservoirs of Pakistan. The plant can be used as a potential alternative for the fish and poultry industry to meet the promptly growing demand for feed. Our study investigates the effect of varying concentrations (ppm) of nutrients like N, P, and their combination, NP on biomass production, carbohydrate, lipid, protein, and mineral (Ca, Mg, Fe, Mn & Zn) contents of L. minor. The varying concentrations of N and P substantially affected the above-stated parameters. The highest biomass yield was recorded in the 30 ppm NP tank as 172 g/m2 day in comparison with the control tank. Higher protein, lipid, and carbohydrate contents were recorded for 30 ppm NP, 20 ppm NP, and 10 ppm NP respectively. Minerals like Ca, Mg, Fe, Mn & Zn increased in 20 ppm P and all N concentrations. The combined application of NP was more effective in boosting the protein, carbohydrate, and lipid content whereas less effective in increasing the mineral contents. A rise in the concentration of N and P showed a positive correlation with the nutritional composition of L. minor.

RESUMO

BACKGROUND: Arctostaphylosuva-ursi(AUU) being rich in polyphenols and arbutin is known to have promising biological activities and can be a potential candidate as a cosmaceutical. Ethosomes encourage the formation of lamellar-shaped vesicles with improved solubility and entrapment of many drugs including plant extracts. OBJECTIVE: The objective of this work was to develop an optimized nanostructured ethosomal gel formulation loaded with AUU extract and evaluated for skin rejuvenation and depigmentation. METHODS: AUU extract was tested for phenolic and flavonoid content, radical scavenging potential, reducing power activity, and in-vitro SPF (sun protection factor) estimation. AUU loaded 12 formulations were prepared and characterized by SEM (Scanning Electron Microscopy), vesicular size, zeta potential, and Entrapment Efficiency (%EE). The optimized formulation was subjected to noninvasive in-vivo investigations after incorporating it into the gel system and ensuring its stability and skin permeation. RESULTS: Ethosomal vesicles were spherical in shape and Zeta size, zeta potential, PDI (Polydispersity Index), percentages of EE and in-vitro skin permeation of optimized formulation (F3) were found to be 114.7nm, -18.9mV, 0.492, 97.51±0.023%, and 79.88±0.013% respectively. AUU loaded ethosomal gel formulation was stable physicochemically and exhibited non-Newtonian behavior rheologically. Moreover, it significantly reduced skin erythema, melanin as well as sebum level and improved skin hydration and elasticity. CONCLUSION: A stable AUU based ethosomal gel formulation could be a better vehicle for phytoextracts than conventional formulations for cosmeceutical applications such as for skin rejuvenation and depigmentation.

RESUMO

Sphaeranthus indicus L. is a medicinal herb having widespread traditional uses for treating common ailments. The present research work aims to explore the in-depth phytochemical composition and in vitro reactivity of six different polarity solvents (methanol, n-hexane, benzene, chloroform, ethyl acetate, and n-butanol) extracts/fractions of S. indicus flowers. The phytochemical composition was accomplished by determining total bioactive contents, HPLC-PDA polyphenolic quantification, and UHPLC-MS secondary metabolomics. The reactivity of the phenolic compounds was tested through the following biochemical assays: antioxidant (DPPH, ABTS, FRAP, CUPRAC, phosphomolybdenum, and metal chelation) and enzyme inhibition (AChE, BChE, α-glucosidase, α-amylase, urease, and tyrosinase) assays were performed. The methanol extract showed the highest values for phenolic (94.07 mg GAE/g extract) and flavonoid (78.7 mg QE/g extract) contents and was also the most active for α-glucosidase inhibition as well as radical scavenging and reducing power potential. HPLC-PDA analysis quantified rutin, naringenin, chlorogenic acid, 3-hydroxybenzoic acid, gallic acid, and epicatechin in a significant amount. UHPLC-MS analysis of methanol and ethyl acetate extracts revealed the presence of well-known phytocompounds; most of these were phenolic, flavonoid, and glycoside derivatives. The ethyl acetate fraction exhibited the highest inhibition against tyrosinase and urease, while the n-hexane fraction was most active for α-amylase. Moreover, principal component analysis highlighted the positive correlation between bioactive compounds and the tested extracts. Overall, S. indicus flower extracts were found to contain important phytochemicals, hence could be further explored to discover novel bioactive compounds that could be a valid starting point for future pharmaceutical and nutraceuticals applications.

RESUMO

Skin care formulations with antioxidants are being widely explored for their benefits to human skin. The purpose of this study was to formulate a stable w/o emulsion containing anthocyanin derived from Malus dosmestica fruit extract and to further explore its beneficial effects on normal human skin. Anthocyanin was extracted using various solvents from the peel of Malus dosmestica fruit. w/o creams containing anthocyanin has been prepared and systematically characterized for various physiochemical properties in terms of stability at varying conditions of storage. An efficacy study has been carried out on 12 male healthy Asian subjects to determine effects of anthocyanin on skin melanin, erythema, skin moisture, trans-epidermal water loss (TEWL) and on skin sebum. Solvent system containing methanol/acetone/water (3.5: 3.5: 3 v/v/v) including 1% formic acid established a best recovery of anthocyanin from fruit peel. W/O emulsions presented promising stability profile when kept at different storage conditions over 90 days period. All skin parameters studied, anthocyanin has been found more efficacious (p<0.05) for its effects on skin melanin and erythema content of skin. It has been shown that a topical application of anthocyanin derived from Malus domestica has substantial potential for human skin system and needs some patient oriented studies could warrant its potential for damaged skin.

RESUMO

In this study, two hydrophilic polymers hydroxypropyl methyl cellulose and beta-cyclodextrin (ß-CD) are used to synthesize highly responsive and spongy polymeric matrices. Porous and stimulus-responsive polymeric network was developed to improve the solubility of acyclovir (ACV) at significant level. Grafting was successfully carried out by free radical polymerization technique. Spongy matrices were characterized by percentage entrapment efficiency, drug loading, solubility studies, FTIR, powder X-ray diffraction, TGA, DSC, XRD, SEM, swelling studies, and in vitro studies. Acute oral toxicity studies were conducted to determine the safety of oral administration of prepared HPMC-ßCD-g-poly(AMPS) formulation. Porous and spongy structures were depicted in SEM images. Complex formation and thermal stability of constituents and drug (ACV) were analyzed by FTIR, TGA, and DSC spectra. XRD analysis revealed reduction in acyclovir crystallinity in spongy matrices. Particle size of optimized formulation was found in the range of 197 ± 2.55 nm. The momentous difference with reference product committed that drug solubility and release characteristics were markedly enhanced by the developed spongy matrices. Toxicity studies endorsed that developed spongy matrices were non-toxic and compatible to biological system. The efficient method of preparation, enhanced solubility, excellent physico-chemical characteristics, high dissolution, and non-toxic HPMC-ßCD-g-poly(AMPS) spongy matrices may be a promising approach for oral delivery of poorly soluble drugs.

RESUMO

Red kidney beans have antioxidant effect and thereby can help in skin smoothening, moisturizing, whitening and have anti-wrinkles effect. The study was based on the formulation of a stable w/o emulsion possessing extract of Phaseolus vulgaris L. seeds, using paraffin oil with the aim to investigate its effect on various skin parameters. The extract, achieved by concentrating ethanolic extract of red kidney beans was embedded in the internal aqueous part of w/o emulsion. An active formulation possessing concentrated extract of red kidney beans and a placebo formulation having no active material in the aqueous phase were formulated and placed at various conditions for the duration of 28 days, to observe the stability of cream. The placebo and formulation were stable at different storage conditions in terms of phase separation and colour changes. Minute liquefaction was observed from 21stday up to 28th day in formulations which were kept at 40°C +75% RH (relative humidity). With the passage of time significant changes were observed in formulation pH while insignificant changes were observed at basic pH. Different effects of creams i.e., placebo and formulations were observed on the human skin by applying them on the volunteer's cheeks for about 8 weeks. A stable w/o emulsion can be formulated by using red kidney beans' extract without any phase separation, liquefaction and colour change over 28 days storage.

RESUMO

Various extrinsic and intrinsic origins slant skins and pledge evident vicissitudes of the skin surface. We explored the effects of dermocosmetic loaded medical Cannabis seed extract and evaluate the improvement on the skin surface in Asian and male volunteers in a split face topographic study. Dermocosmetic and base (without extract) fabricated were directed to apply by volunteers (Asian male) on their right and left cheek, respectively, in the split face skin topographic study up to three months. Efficacy of dermocosmetic versus base was assessed by non- invasive diagnostic technique focusing on skin texture parameters (energy, contrast and variance) and surface evaluation of the living skin (SELS), SEr (skin roughness), SEsc (skin scaliness), SEsm (skin smoothness), SEw (skin wrinkles). Unlike base, dermocosmetic showed significant effects on skin texture parameters (energy, variance and contrast) and SELS (SEr, SEsc, SEsm and SEw) parameters in Asian male volunteers when ANOVA applied. The level of significance was 5%. Dermocosmetic ultimately improved on skin surface and advocacies for anti-aging effects on skin appearance.

The purpose of this investigation was to evaluate the vicissitudes in polyphenolic extract- based high internal phase creams (HIPCs) and effect of storage temperature dependent characteristics. Rheological parameters, that is, power law and IPC analysis with its physical characteristics were exploredat different storage temperatures (8°, 25°, 40° and 40° with 75% relative humidity- RH) with different time intervals up to 2 months of newly formulated poly-phenolic extract- based high internal phase cream and its comparison with base. Polyphenolic- based HIPCs showed non-Newtonian-pseudo plastic tendencies in vicissitudes with time and storage temperatures. Data analysis with Power Law and IPC paste was found to fit to all the rheograms. Flow index, shear sensitivity factor, consistency Index and 10 RPM of freshly prepared HIPCs with and without encapsulated polyphenolic extract were found to be 0.5,0.53, 386.4 cP, and 432.9 cP, respectively.The viscosities were fallen with rise in shear stress.There was no change in color, electrical conductivity, liquefaction and phase separation after centrifugation in any sample of polyphenolic extract-based HIPCs and its base. Polyphenolic- based extract HIPCs behaved non-Newtonian- pseudo plastic tendencies and showed stability up to 2 months and can be directed absolutely to shield skin against ultraviolet radiation (UV) intervened oxidative mutilation.

RESUMO

BACKGROUND: Cosmetics are the products used to beautify the skin. Emulsion is a fine dispersion of two or more immiscible liquids. Sphaeranthus indicus is claimed to be used for skin beautification in folk medicine. Multiple emulsion was formulated containing the extract of S indicus flowers. AIMS: This research study indicates that extract of S indicus flowers contains sufficient amount of polyphenols and also possess good antioxidant activity with mushroom tyrosinase inhibition activity. METHOD: Further, stable multiple emulsion was developed and stability testing was performed for 180 days by keeping the multiple emulsion at 8°C ± 1, 25°C ± 1, 40°C ± 1, and 40°C ± 1 with 75% ± 1 RH. Parameters checked were color change, phase distribution, viscosity, droplet size and size distribution, pH determination, and electrical conductivity. Sun protection factor (SPF) was determined which also showed promising results. Skin testing on human volunteers was done for 3 months after biosafety profiling of the most stable multiple emulsion. RESULTS: This also showed remarkable effects. Skin erythema, melanin, and sebum were reduced. Skin hydration and elasticity were increased. There was also reduction in the number of skin large and small skin pores. Skin spot area was also reduced by the use of multiple emulsion loaded with S indicus flower extract. ANOVA test showed that all the effects produced on skin were significant, ie, P ≤ .05. CONCLUSION: A stable multiple emulsion was developed which produced significant cosmetic effects on human skin.

RESUMO

Pollen morphology of 11 species of family Fabaceae that is, Trifolium alexandrinum, Trifolium resupinatum, Arachis hypogaea, Lathyrus aphaca, Medicago lupulina, Vicia sativa, Lathyrus odoratus, Pongamia pinnata, Melilotus indicus, Medicago polymorpha, Medicago sativa from Pakistan has been investigated by light and scanning electron microscopy. Pollen were generally tricolporate, radially symmetrical, isopolar, elliptic in equatorial view and triangular in polar view under LM. Results showed that pollens were per-prolate (T. alexandrinum), prolate (T. resupinatum, V. sativa, L. odoratus, Melilotus indicus, M. polymorpha, M. sativa) and sub-prolate (A. hypogaea, L. aphaca, M. lupulina, P. pinnata). The larger polar/equatorial (P/E) ratio was found in T. alexandrinum (2.26 µm) and the smallest was found in M. lupulina (1.21 µm). The exine of T. resupinatum was 3.00 µm in thickness while others posses smaller exine thickness. The larger pore diameter was found in P. pinnata (16.01 µm) while others have smaller. The length of colpi was larger in Arachis hypogaea (32.24) while others posses smaller. Eight types of surface ornamentation (Psilate, faintly rugulate). Perforate and rugulate to verrucate have been observed under SEM. The pollens were europalynous type. Pollen morphology proved to be useful for the specific delimitation and serve as a tool for the identification and classification of taxa at specific and generic levels and can also be used as a key for the taxonomic features. Diversity in exine sculpture is helpful indicative characters for the isolation of closely related species. Hence, it is clear that both qualitative and quantitative characters of pollen can be useful for differentiating between taxa at specific level.

RESUMO

BACKGROUND: Phenolic and flavonoid compounds found in plants alleviate the photo-damaging skin conditions by playing a major role in skin rejuvenation. AIMS: The aim of the study was to explore the cosmeceutical effects of Cinnamomum tamala extract. OBJECTIVE: Recent research was aimed to quantify phenols and flavonoids in the natural extract of C tamala leaves, to develop its phyto-cosmetic emulgel and to assess effects of emulgel on healthy human skin. METHOD: Phenols and flavonoids in C tamala (CT) extract were quantified by using ELISA assay. Emulgel formulation loaded with 4% C tamala (CT emulgel) was developed, and its cosmetic effects were evaluated on the cheeks of 13 healthy female test volunteers by comparing with placebo (base). Facial parameters including melanin, erythema, sebum, and visible facial pores (size and area) were studied by using Mexameter® , Sebumeter® , and VisioFace® at regular interval for 90 days. RESULTS: Total phenolic content and total flavonoids content of C tamala leaves extract were found to be 73.08 ± 0.0078 mg GAE/g and 52.63 ± 0.0060 mg QE/g CT extract respectively. As compared to placebo (base), CT emulgel was found to be significantly (P ≤ .05) effective in minimizing skin photo-damaging effects by reducing the levels of melanin, erythema, and sebum and size and count of both fine and large facial pores. CONCLUSION: Cinnamomum tamala leaves extract, being a rich source of phenols and flavonoids minimized the photo-damaging effects by reducing skin melanin, erythema, and excess sebum; improving the skin imperfections by reducing facial pore count and area as assessed by advanced imaging and bioengineering techniques.
