代谢
熊果苷在稀酸中容易水解,生成D-葡萄糖和对苯二酚。预计口服给药的熊果苷会通过胃酸轻易水解为自由的对苯二酚分子。对苯二酚进一步代谢成为主要代谢物,对苯二酚葡萄糖苷酸和对苯二酚硫酸盐。
Arbutin is readily susceptible to hydrolysis in dilute acids to yield D-glucose and hydroquinone. It is expected that orally administered arbutin is easily hydrolyzed to free hydroquinone molecules by stomach acid. Hydroquinone is further metabolized into the main metabolites, hydroquinone glucuronide and hydroquinone sulfate.

  • 在妊娠和哺乳期间的影响
◉ 母乳喂养期间使用概述:少量矿物油可以出现在母乳中,这可能是由于长期吸收化妆品中的碳氢化合物。由于矿物油口服吸收不良,因此很少或没有矿物油会进入婴儿的血液或对母乳喂养的婴儿产生任何不良影响。一项小型研究支持母体矿物油对母乳喂养婴儿肠道的无影响。母乳喂养的母亲口服矿物油是可以接受的,尽管应避免反复使用,因为它可能导致脂溶性维生素的缺乏。在或靠近乳房上使用矿物油或含有矿物油的软膏可能会使婴儿通过舔舐接触到高水平的矿物石蜡。只有水溶性的乳霜产品应该涂抹在乳房上。 ◉ 对母乳喂养婴儿的影响:50位产后第一天的母亲接受了15毫升的矿物油或Magnolax(相当于3.75毫升的矿物油和900毫克的氢氧化镁),尽管没有说明具体有多少人接受了每种产品。如果需要,随后的几天可以给予额外的剂量。他们母乳喂养的婴儿中没有出现明显异常的大便,尽管所有婴儿也接受了补充喂养。 ◉ 对泌乳和母乳的影响:截至修订日期,没有找到相关的已发布信息。
◉ Summary of Use during Lactation:Small amounts of mineral oil can be found in breastmilk, apparently from absorption of hydrocarbons from cosmetics over long periods of time. Because mineral oil is poorly absorbed orally, little or none will not reach the bloodstream of the infant or cause any adverse effects in breastfed infants. One small study supports the lack of effect of maternal mineral oil on the bowels of their breastfed infants. Oral use of mineral oil by the nursing mother is acceptable, although repeated use should be avoided because it may cause a deficiency of fat-soluble vitamins. The use of mineral oil or ointments containing mineral oil on or near the breast may expose the infant to high levels of mineral paraffins via licking. Only water-miscible cream products should be applied to the breast. ◉ Effects in Breastfed Infants:Fifty mothers who were in the first day postpartum received 15 mL of either mineral oil or Magnolax (equivalent to 3.75 mL of mineral oil and 900 mg of magnesium hydroxide), although the exact number who received each product was not stated. Additional doses were given on subsequent days if needed. None of their breastfed infants were noted to have any markedly abnormal stools, although all of the infants also received supplemental feedings. ◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.

熊果苷是氢醌的β-D-葡萄糖苷,是一种美白化妆品成分。与熊果苷相比,氢醌是一种更有效的美白剂,但显示出细胞毒性、肾毒性和遗传毒性。为了评估皮肤微生物群是否能够将熊果苷水解为氢醌,我们测量了主要皮肤微生物群:表皮葡萄球菌和金黄色葡萄球菌的水解活性。所有菌株都能水解熊果苷,活性为0.16-4.51 nmol/min/mg。水解后的氢醌比熊果苷具有更强的1,1-二苯基-2-苦基肼自由基清除活性和酪氨酸酶抑制作用。这些发现表明,正常皮肤微生物群可能由于氢醌的抗氧化作用而增加熊果苷的美白效果。
Arbutin, the beta-D-glucopyranoside of hydroquinone, is a skin whitening cosmetic ingredient. Compared with arbutin, hydroquinone is a more potent skin lightening agent, but shows cytotoxicity, nephrotoxicity, and genotoxicity. To evaluate whether skin microflora can hydrolyze arbutin to hydroquinone, we measured the hydrolytic activity of the main skin microflora: Staphylococcus epidermidis and Staphylococcus aureus. All strains hydrolyzed arbutin, with activities of 0.16-4.51 nmol/min/mg. The hydrolyzed hydroquinone showed more potent 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and tyrosinase inhibition than arbutin. These findings suggest that normal skin microflora may increase the skin lightening effect of arbutin due to the antioxidant action of hydroquinone.

这项研究展示了证据,表明芦荟素和熊果苷联合治疗可以通过不同的作用机制以协同方式抑制酪氨酸酶活性。芦荟素或熊果苷以相似的方式抑制了人和蘑菇酪氨酸酶的酶活性,其半抑制浓度(IC50)分别为0.1 mM和0.04 mM。酶动力学数据的林韦弗-伯克图显示,芦荟素以非竞争性方式抑制酪氨酸酶活性,其Ki值为5.3 mM,而熊果苷则以竞争性方式抑制(Maeda, 1996)。然后我们研究了这些试剂联合治疗是否以协同方式抑制酪氨酸酶活性。结果显示,在0.03 mM熊果苷存在的情况下,0.01 mM芦荟素使蘑菇酪氨酸酶活性降低了对照组的80%,反之亦然。根据Burgi方法计算,抑制效果是协同的。综上所述,我们建议芦荟素与熊果苷联合可以通过非竞争性和竞争性抑制酪氨酸酶活性的组合机制协同抑制黑色素产生。
...This study ... presents evidence that cotreatment of aloesin and arbutin inhibits tyrosinase activity in a synergistic manner by acting through a different action mechanism. Aloesin or arbutin similarly inhibited enzyme activity of human- and mushroom-tyrosinases with an IC50 value of 0.1 or 0.04 mM, respectively. Lineweaver-Burk plots of the enzyme kinetics data showed that aloesin inhibited tyrosinase activity noncompetitively with a Ki value of 5.3 mM, whereas arbutin did it competitively (Maeda, 1996). We then examined whether cotreatment of these agents inhibits the tyrosinase activity in a synergistic manner. The results showed that 0.01 mM aloesin in the presence of 0.03 mM arbutin inhibited activity of mushroom by 80% of the control value and the reverse was also true. The inhibitory effects were calculated to be synergistic according to the Burgi method. Taken together, we suggest that aloesin along with arbutin inhibits in synergy melanin production by combined mechanisms of noncompetitive and competitive inhibitions of tyrosinase activity.

熊果叶干提取物(BLDE)单次口服剂量后,对16名健康志愿者进行了熊果苷代谢物尿排泄的随机交叉设计研究。应用分为两组,一组使用薄膜包衣片(FCT),另一组使用水溶液(AS)。尿液样本分析采用验证的高效液相色谱方法(对羟基苯酚)和验证的毛细管电泳方法(对羟基苯酚-葡萄糖醛酸苷、对羟基苯酚-硫酸盐)。两组从BLDE排入尿液中的总对羟基苯酚当量相似。使用FCT时,64.8%的熊果苷剂量被排泄;使用AS时,66.7%被排泄(p = 0.61)。对羟基苯酚当量的最大平均尿浓度在AS组比FCT组略高,并且峰值出现得更早,尽管这没有达到统计学意义(Cmax = 1.6893 umol/mL 对比 1.1250 umol/mL,p = 0.13;tmax(t中点)= 3.60小时 对比 4.40小时,p = 0.38)。与AS相比,FCT的总对羟基苯酚当量的相对生物利用度为103.3%。受试者间的变异性很大。两组在检测到的代谢物模式(对羟基苯酚、对羟基苯酚-葡萄糖醛酸苷和对羟基苯酚-硫酸盐)之间没有显著差异。
The urinary excretion of arbutin metabolites was examined in a randomized crossover design in 16 healthy volunteers after the application of a single oral dose of bearberry leaves dry extract (BLDE). There were two groups of application using either film-coated tablets (FCT) or aqueous solution (AS). The urine sample analysis was performed by a validated HPLC coolarray method (hydroquinone) and a validated capillary electrophoresis method (hydroquinone-glucuronide, hydroquinone-sulfate). The total amounts of hydroquinone equivalents excreted in the urine from BLDE were similar in both groups. With FCT, 64.8% of the arbutin dose administered was excreted; with AS, 66.7% was excreted (p = 0.61). The maximum mean urinary concentration of hydroquinone equivalents was a little higher and peaked earlier in the AS group versus the FCT group, although this did not reach statistical significance (Cur max = 1.6893 umol/mL vs. 1.1250 umol/mL, p = 0.13; tmax (t midpoint) = 3.60 h vs. 4.40 hr, p = 0.38). The relative bioavailability of FCT compared to AS was 103.3% for total hydroquinone equivalents. There was substantial intersubject variability. No significant differences between the two groups were found in the metabolite patterns detected (hydroquinone, hydroquinone-glucuronide, and hydroquinone-sulfate).

制备方法与用途

熊果苷:美白化妆品的理想增白剂 什么是熊果苷?

熊果苷是一种天然绿色植物提取的成分,又称熊果甙、熊果素、熊果叶甙或杨梅甙。它具有“绿色”、“安全”和“高效”的特点,是理想的皮肤美白活性物质。熊果苷有两种旋光异构体——α型及β型,其中β型具有生物活力。

熊果苷的特性
  • 室温下为白色略带淡黄色粉末,易溶于水、甲醇、乙醇和丙二醇等。
  • 在许多美白保养品中都有添加。
  • 由于从杜鹃花科熊果属植物熊果叶中被发现而得名。此外,它还在杜鹃花科越桔属植物越桔、蔷薇科梨属植物沙梨树(包括西洋梨和小山梨)、虎耳草科虎耳草属植物虎耳草等的叶子中被发现。
  • 它具有镇静、抗炎、抗菌等多种生物学效应,近年来还发现它有抗癌作用。
熊果苷在化妆品中的应用

熊果苷是目前国外流行的最安全有效的美白原料之一。其作用原理类似于美白药物对苯二酚,但刺激性较低,可以自由添加到保养品中,浓度上限高达7%。它能高效美白祛斑,淡化雀斑、黄褐斑、黑色素沉着等。

α-熊果苷

α-熊果苷具有修复肌肤因紫外线引起的损伤的作用,并且不易被皮肤表面的β-葡萄糖苷酶分解,效果约为β-熊果苷的10倍。它能在皮肤表层形成双重效果,抑制黑色素生成。

熊果苷的安全性与适用时间

熊果苷的活性分子能够穿透基底层进行深度淡斑,适用于黄褐斑、黑斑和日晒斑等。5%浓度是最安全和最高效的淡斑浓度。虽然熊果苷被皮肤吸收后会还原成对苯二酚,但添加在保养品中的熊果苷浓度低于7%,不会产生光敏性。

化学性质与用途
  • 熊果苷是一种糖基化的氢醌,用于研究褪黑素生物合成和作为识别、区分和鉴定酪氨酸酶的抑制剂。
  • 它常被用作化妆品的美白剂,并能抑制黑素细胞酪氨酸酶活性,从而防止黑色素生成。

总之,选择可靠的保养品并在白天做好防晒是关键。
