Abstract
Immature mandarin orange is thinned in order to maturation of orange. To use immature mandarin orange as a cosmetic functional material, we investigated the seasonal fluctuation changes in hesperidin and narirutin levels of immature mandarin oranges, and the effects on human skin cells. The contents of hesperidin from Aoshima, Otsu, and Shonan gold, is higher at about a month after flowering. Shonan gold has higher content of narirutin to compere that of Aoshima and Otsu. We found the addition of immature mandarin orange extracts to the human skin fibroblasts and keratinocytes, gene expression level of hyaluronic acid synthase and the hyaluronic acid contents in the medium are higher than that of the control. It was suggested that hesperidin in immature mandarin orange enhances the ability of skin cells to produce hyaluronic acid. Our findings indicate that the immature mandarin orange is a characteristic material on cosmetics and functional foods.

Abstract
Vitiligo is the most common depigmenting disorder characterized by white patches in the skin. The pathogenetic origin of vitiligo revolves around autoimmune destruction of melanocytes in which, for instance, oxidative stress is responsible for melanocyte molecular, organelle dysfunction and melanocyte specific antigen exposure as well as melanocyte cell death and thus serves as an important contributor for vitiligo progression. In recent years, natural products have shown a wide range of pharmacological bioactivities against many skin diseases, and this review focuses on the effects and mechanisms of natural compounds against vitiligo models. It is showed that some natural compounds such as flavonoids, phenols, glycosides and coumarins have a protective role in melanocytes and thereby arrest the depigmentation, and, additionally, Nrf2/HO-1, MAPK, JAK/STAT, cAMP/PKA, and Wnt/β-catenin signaling pathways were reported to be implicated in these protective effects. This review discusses the great potential of plant derived natural products as anti-vitiligo agents, as well as the future directions to explore.

Abstract
Ultraviolet (UV) irradiation induces physiological and morphological skin damage, resulting in skin dryness, wrinkle formation, and loss of elasticity. The basement membrane (BM) has been shown to play crucial roles in binding epidermis to dermis tightly, regulating cell differentiation and proliferation, and signaling protein production. Dietary flavonoids have been revealed to improve the damage caused by UV exposure. Immature Citrus unshiu is known to contain high concentrations of flavonoids such as hesperidin and narirutin. In this study, the effects of immature Citrus unshiu powder (ICP) on photoaged skin were demonstrated using UVB irradiated hairless mice. Oral administration of ICP improved loss of skin hydration and increase of transepidermal water loss. The histological analyses of hairless mice dorsal skin revealed that oral administration of ICP improved UVB-induced overgrowth of epidermal cell, suppressed epidermal cell mortality and BM destruction. Therefore, the administration of ICP could improve photoaging by protecting the tissues around BM.

Abstract
Naringenin, a citrus flavonoid that possesses various biological activities, has emerged as a potential therapeutic agent for the management of a variety of diseases. Studies using cell culture system have shown that naringenin can inhibit inflammatory response in diverse cell types. Moreover, research using various animal models has further demonstrated therapeutic potentials of naringenin in the treatment of several inflammation-related disorders, such as sepsis, fulminant hepatitis, fibrosis and cancer. The mechanism of action of naringenin is not completely understood but recent mechanistic studies revealed that naringenin suppresses inflammatory cytokine production through both transcriptional and post-transcriptional mechanisms. Surprisingly, naringenin not only inhibits cytokine mRNA expression but also promotes lysosome-dependent cytokine protein degradation. This unique property of naringenin stands in sharp contrast with some widely-studied natural products such as apigenin and curcumin, which regulate cytokine production essentially at the transcriptional level. Therefore, naringenin may provide modality for the development of novel anti-inflammatory agent. This review article summarizes our recent studies in understanding how naringenin acts in cells and animal models. Particularly, we will discuss the anti-inflammatory activities of naringenin in various disease context and its potential use, as an immunomodulator, in the treatment of inflammatory related disease.

Abstract
Melanin, the compound primarily responsible in humans for hair, eye and skin pigmentation, is produced by melanocytes through a complicated process called melanogenesis that is catalyzed by tyrosinase and other tyrosinase-related proteins. The abnormal loss of melanin causes dermatological problems such as vitiligo. Hence the regulation of melanogenesis and tyrosinase activity is very important for treating hypopigmentary disorders. Many melanogenesis stimulators have been discovered during the past decade. This article reviews recent advances in research on extracts and active ingredients of plants, synthesized compounds with stimulating effect on melanin synthesis and tyrosinase activity, as well as their influence on the expression of related proteins and possible signaling pathways for the design and development of novel anti-vitiligo agents.

Abstract
Background The derivative of caffeamide exhibits antioxidant and antityrosinase activity. The activity and mechanism of N-(4-methoxyphenyl) caffeamide (K36E) on melanogenesis was investigated. Methods B16F0 cells were treated with various concentrations of K36E; the melanin contents and related signal transduction were studied. Western blotting assay was applied to determine the protein expression, and spectrophotometry was performed to identify the tyrosinase activity and melanin content. Results Our results indicated that K36E reduced α-melanocyte-stimulating hormone (α-MSH)-induced melanin content and tyrosinase activity in B16F0 cells. In addition, K36E inhibited the expression of phospho-cyclic adenosine monophosphate (cAMP)-response element-binding protein, microphthalmia-associated transcription factor (MITF), tyrosinase, and tyrosinase-related protein-1 (TRP-1). K36E activated the phosphorylation of protein kinase B (AKT) and glycogen synthase kinase 3 beta (GSK3β), leading to the inhibition of MITF transcription activity. K36E attenuated α-MSH induced cAMP pathways, contributing to hypopigmentation. Conclusions K36E regulated melanin synthesis through reducing the expression of downstream proteins including p-CREB, p-AKT, p-GSK3β, tyrosinase, and TRP-1, and activated the transcription factor, MITF. K36E may have the potential to be developed as a skin whitening agent.

Abstract
The present study was aimed to evaluate the radioprotective effects of naringenin in vivo using Swiss albino mice as a model system. Oral administration of 50 mg/kg body weight of naringenin for 7 days prior to radiation exposure protected mice against radiation-induced DNA, chromosomal and membrane damage. Naringenin pretreatment also increased the antioxidant status of irradiated mice. Multiple factors operating at cellular and molecular levels led to increased endogenous spleen colonies and survival of mice. Although naringenin induces apoptosis in cancer cells we found that it can protect against radiation-induced apoptosis in normal cells by modulating the expression of p53, Bax, and Bcl-2. The results from the present study indicate that naringenin inhibits the NF-kB pathway and down regulates radiation-induced apoptotic proteins resulting in radioprotection at the cellular, tissue and organism levels.

Abstract
OBJECTIVE Volatile essential oils of mint species are used for cosmetics and in skin care products. In this study, we evaluated the main chemical components of the lime mint and the anti-melanogenic properties of its main components. METHODS The essential oil was analysed by gas chromatography-mass spectrometry (GC/MS). The anti-melanogenic effects of mint essential oil and β-caryophyllene were investigated in B16F10 murine melanoma cells. RESULTS The main components of lime mint essential oil were found to be D-limonene (41.10%), D-carvone (8.58%), δ-selinene (6.73%) and β-caryophyllene (6.24%). The lime mint essential oil reduced melanin production in a dose-dependent manner in murine B16F10 cells. β-Caryophyllene, one of the main compounds in lime mint essential oil, could reduce melanogenesis by down-regulating the expression of MITF, TRP-1, TRP-2 and tyrosinase, resulting in a decrease in melanin content decrease. CONCLUSION These results reveal that lime mint essential oil and β-caryophyllene are considered to be valuable as potential skin-whitening agents.

Abstract
Danshensu (DSU) and salvianolic acid B (SAB) are the primary water-soluble compounds of Salvia miltiorrhiza Bunge (Lamiaceae). In this study, we analyzed the effects of DSU, SAB and a S. miltiorrhiza extract (SME) on cell proliferation. Additionally, the effects of DSU and SAB on collagen synthesis in Detroit 551 human normal fibroblast cells and on melanin production in B16 melanoma cells were verified. The results demonstrated that SME can enhance the proliferation of Detroit 551 cells and that this boost may be caused by DSU and SAB. This research showed that SME, DSU and SAB all have the ability to increase the production of collagen in Detroit 551 cells. The results also confirmed that DSU and SAB can attenuate the α-MSH-stimulated melanin production of B16 cells by inhibiting tyrosinase activity. Therefore, SME, DSU and SAB each have the potential to be utilized as active ingredients in wound healing or cosmetic treatments. In the future, DSU and SAB could also be used as functional components for treating hyperpigmentation.

Abstract
We investigated the effects of an aqueous alcohol extract of Rhodiola rosea (R. rosea) and its hydrolysate on melanin synthesis and the mechanisms mediating the activity. The ratio of tyrosol to salidroside was 2.3 in hydroalcoholic extract, and 51.0 in hydrolysate. We found that R. rosea extract and its hydrolysate inhibited melanin synthesis and tyrosinase activity in mouse melanoma cells (B16F0 cells). R. rosea extract also inhibited gene and protein expression of melanocortin 1 receptor (MC1R) and inhibited c-AMP response element binding protein (CREB) phosphorylation, suppressed the activation of AKT and glycogen synthase kinase-3 beta (GSK3β), and inhibited the expression of microphthalmia-associated transcription factor (MITF) and tyrosinase-related protein 1 (TRP-1). R. rosea hydrolysate inhibited the phosphorylation of CREB, the activation of AKT and GSK3β, and the expression of MITF and tyrosinase. Our results suggest that R. rosea extract is a novel tyrosinase inhibitor and that it exerts its effects by regulating the CREB/MITF/tyrosinase pathway in B16F0. Further in vivo studies are needed to determine the effectiveness of R. rosea extract as a skin whitening agent.

Tyrosol and its analogues inhibit alpha-melanocyte-stimulating hormone induced melanogenesis. Int J Mol Sci 2013; 14:23420-40.

Abstract
Melanin is responsible for skin color and plays a major role in defending against harmful external factors such as ultraviolet (UV) irradiation. Tyrosinase is responsible for the critical steps of melanogenesis, including the rate-limiting step of tyrosine hydroxylation. The mechanisms of action of skin hypopigmenting agents are thought to be based on the ability of a given agent to inhibit the activity of tyrosinase and, hence, down regulate melanin synthesis. Tyrosol and its glycoside, salidroside, are active components of Rhodiola rosea, and in our preliminary study we found that Rhodiola rosea extract inhibited melanogenesis. In this study, we examined the effects of tyrosol and its analogues on melanin synthesis. We found that treatment of B16F0 cells to tyrosol (1), 4-hydroxyphenylacetic acid (5), 3-hydroxyphenylacetic acid (6), 2-hydroxyphenylacetic acid (7), or salidroside (11) resulted in a reduction in melanin content and inhibition of tyrosinase activity as well as its expression. Tyrosol (1), 4-hydroxyphenylacetic acid (5) and 2-hydroxyphenylacetic acid (7) suppressed MC1R expression. Tyrosol (1), 4-hydroxyphenylacetic acid (5), 3-hydroxyphenylacetic acid (6), and 2-hydroxyphenylacetic acid (7) inhibited α-MSH induced TRP-1 expression, but salidroside (11) did not. All the compounds did not affect MITF and TRP-2 expression. Furthermore, we found that the cell viability of tyrosol (1), 4-hydroxyphenylacetic acid (5), 3-hydroxyphenylacetic acid (6), and 2-hydroxyphenylacetic acid (7) at concentrations below 4 mM and salidroside (11) at concentrations below 0.5 mM were higher than 90%. The compounds exhibited metal-coordinating interactions with copper ion in molecular docking with tyrosinase. Our results suggest that tyrosol, 4-hydroxyphenylacetic acid, 3-hydroxyphenylacetic acid, 2-hydroxyphenylacetic acid, and salidroside are potential hypopigmenting agents.

Pharmacokinetics of hesperetin and naringenin in the Zhi Zhu Wan, a traditional Chinese medicinal formulae, and its pharmacodynamics study. Phytother Res 2012; 27:1345-51. [PMID: 23148023 DOI: 10.1002/ptr.4867] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2012] [Revised: 09/21/2012] [Accepted: 09/29/2012] [Indexed: 01/24/2023]
Abstract
Zhi Zhu Wan (ZZW), a classical Chinese medical formulae consisted of Atractylodes Rhizome and Fructus Citrus Immaturus, has been commonly used for treatment of gastrointestinal diseases. Hesperetin and naringenin are the main components of ZZW, and both can alleviate intestinal tract disorders. In this work, plasma pharmacokinetics and pharmacodynamics characteristics of ZZW after oral administration were investigated using a rapid and sensitive ultra performance liquid chromatography-tandem mass spectrometry method with an electrospray ionization source in positive ion mode. Biosamples were prepared using methanolic precipitation, and the separation of hesperetin and naringenin was achieved on a Waters ACQUITY HSS BEH (2.1 mm × 5 mm, 1.7 µm) column by linear gradient elution, and the total run time was only 3 min. Data were analyzed and estimated using WinNonlin Professional version 5.1. With pharmacokinetic analysis, the estimated pharmacokinetic parameters (i.e. C(max), area under the concentration-time curve (AUC) and t(1/2)), were C(max) = 776.06 ng/mL, AUC = 9473 ng/mL·h, t1/2 = 5.26 h for hesperetin and C(max) = 2910.6 ng/mL, AUC = 40607.9 ng/mL·h, t1/2 = 4.69 h for naringenin, respectively. In the present study, we have also valuated and clarified the effect of ZZW on small intestinal movement. It was found that ZZW can accelerate intestinal motility in mice and may hold a promising treatment for intestinal diseases.

Chiang HM, Chen HC, Lin TJ, Shih IC, Wen KC. Michelia alba extract attenuates UVB-induced expression of matrix metalloproteinases via MAP kinase pathway in human dermal fibroblasts. Food Chem Toxicol 2012; 50:4260-9. [PMID: 22922035 DOI: 10.1016/j.fct.2012.08.018] [Citation(s) in RCA: 62] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2012] [Revised: 08/01/2012] [Accepted: 08/09/2012] [Indexed: 10/28/2022]
Abstract
Solar ultraviolet (UV) radiation can cause skin photoaging by inducing secretion of matrix metalloproteinases (MMPs). It has been reported that MMPs, especially MMP-1, -3 and -9, reduce elasticity of the dermis by degrading collagen. Polyphenols are a group of compounds that exist mainly in glycosides in the plants and they may transform to aglycone after hydrolysis. Polyphenols can inhibit MMP expression and elastase activity. In this study, we investigated the effects of Michelia alba extract (MAE) on expression and activity of MMPs in human skin fibroblast cultures after UVB exposure. The results showed that MAE and its hydrolysates (MAH) inhibited collagenase and elastase activities. In addition, MAE exhibited antioxidant activity, elevated hyaluronic acid content and inhibited UVB-induced MMP-1, MMP-3 and MMP-9 expression. In addition, the zymography assay revealed that MAE also inhibited MMP-9 activity. We also found that MAE inhibited UVB-induced ERK and JNK kinase but not p38 kinase expression, suggesting that MAE may regulate the UVB-induced expression of MMP-1, MMP-3 and MMP-9 via the ERK and JNK kinase pathway. MAE could restore total collagen synthesis reduced by UVB. The results also suggest that MAE treatment may prevent UVB-induced extracellular matrix damage by inhibiting the expression of MMP-1, MMP-3 and MMP-9 through the MAP kinase pathway. Our findings imply that MAE is an effective agent against UVB-induced photodamage.
