ABSTRACT

OBJECTIVE: The current study aimed to provide preliminary insights into potential biopharmaceutical applications of Carica papaya seed extract by evaluating its phytochemical and biological profiles. Furthermore, the study aimed to develop a stable oil-in-water (O/W) emulsion for the effective delivery of antioxidant-rich biologicals for cosmetic purposes. METHODS: The hydroethanolic (ethanol 80%: 20% water) extract of C. papaya seeds was prepared via maceration technique. The chemical composition was carried out through preliminary phytochemical screening and estimation of total phenolic contents (TPC) and total flavonoid contents (TFC). The biological profile of the extract was explored using various in-vitro antioxidant methods. The homogenization procedure was used to create a cream of O/W and various tests were applied to assess the stability of the emulsion. By keeping the emulsion at different storage conditions (8 ± 0.5°C, 25 ± 0.5°C, 40 ± 0.5°C, and 40 ± 0.5°C ± 75% relative humidity [RH]) for a period of 28 days), the physical stability parameters of the emulsion, including pH, viscosity, centrifugation, phase separation, and conductivity, as well as rheological parameters and organoleptic parameters (odor, color, liquefaction, and creaming), were assessed. RESULTS: The preliminary phytochemical screening assay revealed the presence of various plant secondary metabolites including alkaloids, phenolics, flavonoids, tannins, saponins, and quinones. The extract was found to be rich in TPC and TFC. The in vitro antioxidant study gave maximum activity in the DPPH method. The plant extract containing cosmetic cream exhibited remarkable stability during the entire research. Data gathered indicated that no phase separation or liquefaction was seen after the experimental period. Throughout the experimental period, a small variation in the pH and conductivity values of the base and formulation was seen. CONCLUSION: The findings suggest that the seed extract of C. papaya is a rich source of polyphenols with antioxidant potential and can be a promising alternative for the treatment of various ailments. The stability of emulsion paves the way for its utilization as a carrier for the delivery of 3% C. papaya seed extract and applications in cosmetics products.

ABSTRACT

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.

ABSTRACT

There is a long history of natural products for the treatment of infections and diseases. The objective of present study was to investigate the organoleptic, microscopic, physico-chemical, phytochemical, antidiarrheal and antidiabetic potential of leaf, flowering bud and stem bark of Moringa oleifera L. Macroscopic, microscopic, physico-chemical parameters and phytochemical screening were carried out. Diarrhea was induced with castor oil (10ml/kg), verapamil (3, 10 and 30mg/kg) were used as standard antidiarrheal drug and extract of Moringa oleifera at (100, 300 and 1000mg/kg) was used for treatment. Alpha glucosidase inhibitory assay was carried out by using acarbose (0.5mM) and extracts (5.0 mg/Ml). Diabetes was induced by alloxan (150mg/kg), while glibenclamide (10mg/kg) was used as standard drug, and extracts (at the doses of 500mg/kg) were used to determine the antidiabetic activity. Results showed the presence of primary and secondary metabolites, treatment at the dose of 1.0g/kg of leaf, flowering bud and stem bark showed 94 ±2.527, 85.42±5.460 and 84.58±6.138% protection respectively whereas verapamil (10mg/kg) showed 94.84±3.27% protection. Alpha glucosidase inhibition of stem bark (0.5mg/ml) was 95.43±1.47 and flowering bud 94.78±1.25 whereas acarbose (5mM) inhibition was 92.23±0.14%. Stem bark and flowering bud extract (500mg/kg) decreases the blood glucose level from 388.5±35.83 to 226.3±47.10 and 322.5±48.35 to 173.8±29.5 respectively whereas glibenclamide (10 mg/kg) decreases the blood glucose level from 320.7±22.9 to 146.3±17.7 and increases the body weight of the experimental animal. It was concluded from the results that stem bark has strong antidiabetic potential while leaves of the plant have promising antidiarrheal effect.

ABSTRACT

Saussurea lappa (SL) has been reported for its antioxidant and anti-ageing properties. Due to this reason it can be incorporated in a stable phytoformulations for cosmetic use. The objective of the study was to evaluate the anti-aging potential of cosmetic o/w emulsion containing the botanical extract of SL. An emulsion (o/w) was prepared using TEGO® Care 450 (Polyglceryl-3-Methyl Glucose Distearate) emulsifier and final emulsion was loaded with 4 % extract of SL in aqueous phase. This emulsion evaluated for its antioxidant and anti-ageing properties on healthy human subjects using a non-invasive technique called surface evaluation of living skin (SELS). The formulation containing SL extract showed significant (p<0.05) changes in Skin roughness (SEr) as -3.13%, -6.26%, -9.39%; Skin Scaliness (SEsc) as - 4.19%, -8.39%, -12.58%; Skin wrinkles (SEw) as -0.5%, -1.08%, -1.63%; and Skin smoothness (SEsm) as 3.28%, 6.57%, 9.85%, respectively, after 30, 60 and 90 days of continous use. Topical application of the cosmetic cream containing SL extract exerts have a significant anti-aging effects, perhaps due to the presence of Kaempferol, gallic acid, Caffeic acid and other essential phenolics.
