ABSTRACT

Sacha inchi (Plukenetia volubilis) oil is constituted with macronutrients and the health benefit fatty acids. In this context, the efficient of Sacha inchi oil for anti-aging product is presented. The light-clear yellowish seed oil of Sacha inchi was revealed on its physicochemical properties that are in the same range of the commercializing plant-oil supplied for topical products. The oil was GC/MS exhibited to be constituted with α-linolenic (51.72%) and linoleic (24.3%) acids, with unsaturated/saturated fatty acids ratio of 21.26. The oil was noted onto its potent in vitro antioxidant activity assessed by ABTS, DPPH and FRAP assays. In addition, the oil (1-3%) was proved to be safe in normal human fibroblast cells. Furthermore, the oil exhibited cellular antioxidant with inhibitory effect against MMP-2. Sacha inchi oil is therefore highlighted as a potential source of nutraceutical especially for anti-aging product. The oil is specified for the product development in terms of physicochemical, chemical and biological profiles. Innovative processing of Sacha inchi is therefore encouraged as the promising plant for anti-aging product.

ABSTRACT

Tea (Camellia spp.) is an important medicinal herb. C. sinensis var. sinensis is the most studied tea variety due to its more preferred flavor than C. sinensis var. assamica (Assam tea), the less economic importance with more bitter variety. A bitter taste highlights its potential as a candidate source for tea catechins, the health beneficial actives applicable for ageing treatment. Nonetheless, indicative data for tea on UV-induced and senescent ageing remain unclarified. Assam tea extract (ATE) was prepared and standardized in terms of TPC, TFC and TTC. EGCG was HPLC quantified as the prime ATE catechin. In vitro antioxidant activity of ATE was exhibited with ABTS, DPPH and FRAP assays. ATE's cellular antioxidant activity was indicated in HDFs at a stronger degree than ascorbic acid. The photoaging protection of ATE was evidenced in a coculture of HaCaT cells and HDFs. ATE markedly suppressed UV-induced IL-6, IL-8, MMP-1 and MMP-9 expressions. The proficiency of ATE targeting on senescent ageing was demonstrated in an ex vivo human skin model, where IL-6 and MMP-1 expressions were suppressed, whilst hyaluronic acid and collagen syntheses were promoted. ATE was chemically stabled as indicated by the catechin contents and color parameters following 6 months storage under conditions recommended for topical product. ATE enriched in catechins warrants its applicability as a new generation of photoaging protectant agent promising for the prevention and treatment for senescent ageing. The findings indicate the proficiency of ATE for innovative anti-ageing agent.

ABSTRACT

Acanthus spp. have been documented in traditional Thai herbal medicine and are applicable for the treatment of inflamed skin with wound healing property. Nonetheless, the scientific evidence necessary to prove the herb's doctrine has not yet been revealed. Verbascoside-rich extracts of the herbal medicine A. ebracteatus Vahl., were therefore prepared. The extracts and verbascoside were examined for their wound healing abilities using a scratch assay with fibroblasts. The anti-inflammatory effect suppressing MMP-9 was assessed in cocultures of keratinocyte (HaCaT cells) and fibroblasts. The extracts significantly improved wound healing compared with the control (p < 0.001). The wound healing effect of the extracts significantly (p < 0.01) increased with increasing verbascoside content. It should be noted that the extract was significantly (p < 0.05) better than verbascoside at the same test concentration. The extracts were capable of protecting cocultures of HaCaT cells and fibroblasts from photodamage. The extracts significantly (p < 0.001) suppressed cellular MMP-9 secretion following UV exposure, showing a better effect than that of verbascoside (p < 0.01). A. ebracteatus extract is promising for wound healing and photoprotection, and a prominent source of verbascoside. Verbascoside-rich A. ebracteatus could be utilized for the development of innovative skin-care products.

ABSTRACT

Skin aging is accompanied by an increase in the number of senescent cells, resulting in various pathological outcomes. These include inflammation, impaired barrier function, and susceptibility to skin disorders such as cancer. Kaempferia parviflora (Thai black ginger), a medicinal plant native to Thailand, has been shown to counteract inflammation, cancer, and senescence. This study demonstrates that polymethoxyflavones (5,7-dimethoxyflavone, 5,7,4'-trimethoxyflavone, and 3,5,7,3',4'-pentamethoxyflavone) purified from K. parviflora rhizomes suppressed cellular senescence, reactive oxygen species, and the senescence-associated secretory phenotype in primary human dermal fibroblasts. In addition, they increased tropocollagen synthesis and alleviated free radical-induced cellular and mitochondrial damage. Moreover, the compounds mitigated chronological aging in a human ex vivo skin model by attenuating senescence and restoring expression of essential components of the extracellular matrix, including collagen type I, fibrillin-1, and hyaluronic acid. Finally, we report that polymethoxyflavones enhanced epidermal thickness and epidermal-dermal stability, while blocking age-related inflammation in skin explants. Our findings support the use of polymethoxyflavones from K. parviflora as natural anti-aging agents, highlighting their potential as active ingredients in cosmeceutical and nutraceutical products.

ABSTRACT

OBJECTIVES: Para rubber (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.)) is the important crop of the word. It has been vastly used in biomedical products. However, its pharmacologically application besides the latex is sparely to be explored especially the seed. Cellular biological activities of the standardized para rubber seed oil for hair loss treatment were therefore assessed. METHODS: Para rubber seed oil was prepared and standardized using GC/MS on the basis of its pharmacologically active fatty acids. The oil was safety assessed in human dermal papilla and DU-145 human prostate carcinoma. Cellular antioxidant activity was determined as well as proliferation stimulating efficacy and inhibitory effect against 5α-reductase. RESULTS: Oleic acid, fatty acid of cutaneous benefits, was majorly detected in the oil and followed by linoleic, palmitic, and stearic acids. The standardized para rubber seed oil was proved to be safe on human follicle dermal papilla and DU-145 human prostate carcinoma at the concentration of 0.1-50 and 0.1-100 µg/mL, respectively. The standardized para rubber seed oil stimulated the cell proliferation and posed cellular antioxidant activity in human dermal papilla at a comparable potency to minoxidil, dutasteride and vitamin C at the same tested concentration. In addition, the standardized para rubber seed oil inhibited 5α-reductase as examined in DU-145 human prostate carcinoma, although at a lesser degree than the standards at the same tested concentration. CONCLUSIONS: The standardized para rubber seed oil is evidenced as the safe and efficient bio-oil to be used for hair growth stimulating or reduce/suppress hair loss treatment.

ABSTRACT

The pomegranate phenolics are reported to have cutaneous benefits and to be effective in treating skin disorders, including hyperpigmentation. In this context, a preparation method was developed by which to obtain phenolic-rich pomegranate peel extract. Sinapic acid was presented as the major pomegranate peel phenolics, followed by gallic and ellagic acids, and 4 additional phenolics. The extract exhibited strong antioxidant activity with an in vitro tyrosinase inhibitory effect. The skin hyperpigmentation treating potency was confirmed by the suppression of cellular melanogenesis through tyrosinase and TRP-2 inhibitions as examined in the B16F10 melanoma cells. Cellular antioxidant and proliferative activities of the extract toward human dermal fibroblasts were evidenced, as well as an inhibitory effect against MMP-2. The extract was developed into the stable serum and mask. The products were proved to be non-irritated in 30 Thai volunteers participating in a single application closed patch test. A split-face, randomized, double-blind, placebo-controlled test of the skin lightening effect was evaluated in the 30 volunteers over 28 consecutive daily treatments and monitored by the Mexameter MX 18. The active serum and mask were better in facial skin lightening efficacy than the placebo (p < 0.005). That was in accordance with the sensory evaluation scored by the volunteers. Phenolic-rich pomegranate peel extract is evidenced as a safe herbal derived material promising for skin hyperpigmentation treatment. Supportive information regarding chemical and biological profiles is presented with the confirmed safety and cutaneous benefits in volunteers.

ABSTRACT

Butterfly pea (Clitoria ternatea) anthocyanins are important natural food colorants. However, the instability hinders industrial applications. The butterfly pea anthocyanin extract was prepared and mixed with biopolymeric wall systems such as maltodextrin (MD) and gum arabic (GA), MD and gelatin (GE), and MD and guar gum at 1/4 and 1/5 ratios with or without acidified condition, and assessed using the accelerated stability test. The total anthocyanin content (TAC) and color were reassessed. The biopolymeric walls of MD and GA (1/5) under acidified condition exhibited best stability enhancement in comparison with the unprotected one (12.04% ± 4.49% and 85.37% ± 0.22% TAC reduction, respectively). a* and b shifts of the protected system were 4.76% ± 0.00% and 0.28% ± 0.00%, respectively. The particle size of this system was 95.44 ± 1.57 µm. This stabilized anthocyanin extract can, therefore, be used in food, pharmaceutical, and cosmetic industries.

ABSTRACT

BACKGROUND: Guava has benefit phytochemicals that are important for skin-disorder treatment. Nevertheless, its efficacy against oily skin has never been reported. AIMS: The guava toner was developed and clinical evaluated. METHODS: The base toner was formulated, accelerated stability tested, and sensory-evaluated in 10 volunteers. The highest preference base was incorporated with guava extract, stability examined, and skin irritation assessed in 21 volunteers by a single application close patch test. Anti-sebum efficacy was split-face, randomized, single-blind placebo-controlled evaluated in 21 volunteers for 28 days and monitored by Sebutape® on forehead and nose. RESULTS: The stable toner base with the greatest preference (83.20 ± 1.85%) was incorporated with 3%, 4.5%, and 6% of guava extract. The toners were stable with none of skin irritation. The toner with 6% guava extract was selected for efficacy evaluation. Guava toner significantly reduced oiliness of forehead (13.10 ± 3.67%, P < 0.05) and nose (21.43 ± 3.21%, P < 0.001) better than the base toner. The activity on nose was significantly noted (10.72 ± 3.51%, P < 0.05) since the 3rd week of application. CONCLUSIONS: Anti-sebum guava toner was efficiently evidence approved and suitable for a daily application to improve the efficacy.

ABSTRACT

Peel extracts of litchi and rambutan, and that of tamarind seed coat were investigated in relation to their utility in skin-aging treatments. Standardized extracts of tamarind were significantly (p < 0.05) more efficient at O2 •- scavenging (IC50 = 27.44 ± 0.09) than those of litchi and rambutan (IC50 = 29.57 ± 0.30 and 39.49 ± 0.52 µg/ml, respectively) and the quercetin standard (IC50 = 31.88 ± 0.15 µg/ml). Litchi extract proved significantly (p < 0.05) more effective for elastase and collagenase inhibition (88.29 ± 0.25% and 79.46 ± 0.92%, respectively) than tamarind (35.43 ± 0.68% and 57.69 ± 5.97%) or rambutan (31.08 ± 0.38% and 53.99 ± 6.18%). All extracts were safe to human skin fibroblasts and inhibit MMP-2, with litchi extract showing significantly (p < 0.01) enhanced inhibition over the standard, vitamin C (23.75 ± 2.74% and 10.42 ± 5.91% at 0.05 mg/ml, respectively). Extracts suppress melanin production in B16F10 melanoma cells through inhibition of tyrosinase and TRP-2, with litchi extract being the most potent, even more so than kojic acid (standard). These results highlight the potential for adding value to agro-industrial waste, as the basis for the sustainable production of innovative, safe, anti-aging cosmetic products.

ABSTRACT

Abstract Application of sunscreen is the most established method of protecting skin from premature aging and photoaging. In this study, the passion fruit seed extract, enriched with biologically beneficial phenolics, was formulated into sun-protective makeup product. The UVB protection of concealer mousse was found have twofold higher sun protection factor (SPF) than the liquid foundation (15.48 ± 1.60 and 5.88 ± 0.30, respectively). The SPF of concealer mousse as well as the liquid foundation containing 0.1% and 0.3% of the passion fruit seed extract were 18.75 ± 0.28, 18.99 ± 0.71 and 9.32 ± 0.88, 9.77 ± 1.37, respectively. Therefore, the concealers with a similar sun-protective efficacy (p>0.05) were included for stability test accordingly. The sun-protective efficacy did not significantly shift (p>0.05) because the 0.1% and 0.3% passion fruit extract concealers had SPF of 18.09 ± 1.48 and 18.60 ± 1.21. The concealers exhibited UVA photoprotection with a boot star rating of 4 and a critical wavelength wider than 370 nm. The safety of 0.1% passion fruit extract concealer mousse was assessed. It did not cause skin irritation when assessed in human volunteers. This sunscreen makeup product provides UVA and UVB protection and is therefore suitable for daily application.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: While rice is one of the most important global staple food sources its extracts have found many uses as the bases of herbal remedies. Rice extracts contain high levels of phenolic compounds which are known to be bioactive, some of which show cutaneous benefits and activity towards skin disorders. This study highlights an assessment of the cellular activity and clinical efficacy of rice panicle extract, providing necessary information relevant to the development of new cosmetic products. MATERIALS AND METHODS: Jasmine rice panicle extract was standardized, and the level of phenolics present was determined. In vitro anti-aging, and extract activity towards melanogenesis was conducted in B16F10 melanoma cells, and antioxidant activity was assessed in human skin fibroblast cell cultures. Topical product creams containing the extract were developed, and skin irritation testing using a single application closed patch test method was done using 20 Thai volunteers. Randomized double-blind, placebo-controlled efficacy evaluation was undertaken in 24 volunteers over an 84d period, with the results monitored by Corneometer® CM 825, Cutometer® MPA 580, Mexameter® MX 18 and Visioscan® VC 98. RESULTS: Jasmine rice panicle extract was shown to have a high content of p-coumaric, ferulic and caffeic acids, and was not cytotoxic to the cell lines used in this study. Cells treated with extract suppressed melanogenesis via tyrosinase and TRP-2 inhibitory effects, which protect the cell from oxidative stress at doses of 0.1mg/ml or lower. The jasmine rice panicle preparations (0.1-0.2%) were safe (MII=0), and significantly (p<0.05) increased skin hydration levels relative to baseline. Skin lightening, and anti-wrinkle effects related to skin firmness and smoothness were observed, in addition to a reduction in skin wrinkling. Improvements in skin biophysics of both 0.1% and 0.2% extracts were showed to be comparable (p>0.05). CONCLUSIONS: Jasmine rice panicle extract having high levels of phenolics shows cutaneous benefits as the basis for skin aging treatments, as indicated through in vitro cytotoxicity assessments and skin testing in human subjects.

ABSTRACT

BACKGROUND: Natural remedies for treating dandruff are becoming popular. MATERIALS AND METHODS: A randomized, double-blind, placebo-controlled, split-head efficacy evaluation was conducted 30 Thai volunteers aged 20-60 years experiencing dandruff measured at level 3 on D-Squame® scale. An easy to use hair tonic containing essential oil of lemongrass (Cymbopogon flexuosus) active against lipophilic yeasts was developed and then evaluated for efficacy and preference. The base formulation with the significantly highest preference (p < 0.05) was stowed with the oil at 5, 10 or 15%. Subjects applied the formulation twice a day, and an efficacy assessment with D-Squame® scale was conducted on days 7 and 14 of application. RESULTS: The application of lemongrass oil hair tonics with 5, 10, or 15% reduced dandruff significant (p < 0.005) at day 7 (33, 75, and 51%) and increased the effect even more (p < 0.005) at day 14 (52, 81, and 74%). CONCLUSION: The hair tonic formulation with 10% of lemongrass oil seems to be the most effective preparation.

ABSTRACT

Skin aging is caused by several factors. Ultraviolet (UV) exposure as well as oxidative stress elevates inflammatory mediators causing degradation of the extracellular matrix, which is regarded as the major cause of skin wrinkles, one of the signs of aging. Topical applications of active ingredients protect against dermal photodamage and scavenge radicals that can delay skin aging. Matrix metalloproteinase inhibitors against degradation of collagen, elastin, and hyaluronan are the key strategy to combat cutaneous aging. In addition, active ingredients with the efficacy to enhance extracellular matrix production, including those with UV protection efficacy, play an important role in protecting the skin from aging. Naturally derived compounds for combating skin wrinkles are gaining more interest among the consumers as they are perceived to be milder, safer, and healthier. This article, therefore, briefly addresses the causes of skin aging and extensively summarizes on herbs appraisal for skin wrinkles treatment. Therefore, delaying aging of skin using the functional herbs would maintain the individual's appearance with high esthetic and psychosocial impacts.

ABSTRACT

The volatile profiles of aroma extracts prepared from the flower of Gardenia jasminoides by different methods were investigated using gas chromatography-mass spectrometry. The enfleurage extraction using spermaceti wax and palm oil afforded the best aroma extract with a preference that was significantly (p < 0.05) better than those from solvent extractions, as sensorially evaluated in 43 volunteers. The odor quality of the absolute de enfleurage was similar to the floral scent of fresh gardenia, as confirmed in 152 volunteers. Although female volunteers were insignificantly (p > 0.05) better sensed than male volunteers, age was significant (p < 0.05). The nuance gardenia floral scent was contributed by farnesene, Z-3-hexenyl tiglate, Z-3-hexenyl benzoate, and indole. The relaxing and refreshing sensations of the gardenia odor suggest its applications in body care, cleansing products, and perfume. This study addresses the increasing interest in floral fragrances. The aroma profile and sensory property of this sweet and elegant scent flower will strengthen and expand the applications of gardenia from traditional medicine to those of perfumery and the field of phytochemistry.

ABSTRACT

Para rubber seed was macerated in petroleum ether and n-hexane, individually, for 30 min. The extraction was additionally performed by reflux and soxhlet for 6 h with the same solvent and proportion. Soxhlet extraction by petroleum ether afforded the greatest extractive yield (22.90 ± 0.92%). Although antioxidant activity by means of 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay was insignificantly differed in soxhleted (8.90 ± 1.15%) and refluxed (9.02 ± 0.71%) by n-hexane, soxhlet extraction by n-hexane was significantly (p < 0.05) potent scavenged 2,2'-azino-bis(3-ethylbenzothaiazoline)-6-sulfonic acid) or ABTS radical with trolox equivalent antioxidant capacity (TEAC) of 66.54 ± 6.88 mg/100 g oil. This extract was non cytotoxic towards normal human fibroblast cells. In addition, oleic acid and palmitic acid were determined at a greater content than in the seed of para rubber cultivated in Malaysia, although linoleic and stearic acid contents were not differed. This bright yellow extract was further evaluated on other physicochemical characters. The determined specific gravity, refractive index, iodine value, peroxide value and saponification value were in the range of commercialized vegetable oils used as cosmetic raw material. Therefore, Para rubber seed oil is highlighted as the promising ecological ingredient appraisal for cosmetics. Transforming of the seed that is by-product of the important industrial crop of Thailand into cosmetics is encouraged accordingly.
