Abstract
Description
本發明涉及一種特定植物萃取物之新調配物。The present invention relates to a new formulation of specific plant extracts.
該特定植物萃取物係白桑樹之葉萃取物。The specific plant extract is the leaf extract of the white mulberry tree.
白桑(拉丁名為Morus alba)係一快速生長且小型至中等尺寸之桑樹，其可生長至10-20公尺高。 此物種最初原產於中國北部，而現今已於許多其他國家被廣泛地栽培與歸化，諸如美國、墨西哥、澳大利亞、吉爾吉斯、阿根廷、土耳其、伊朗等。White mulberry (Latin name Morus alba) is a fast-growing small to medium-sized mulberry tree that can grow to a height of 10-20 meters. This species was originally native to northern China, and now it has been widely cultivated and naturalized in many other countries, such as the United States, Mexico, Australia, Kyrgyzstan, Argentina, Turkey, Iran, etc.
桑葉在亞洲國家具有很長的藥用歷史，特別是中國。近年來，植物化學家已自桑葉分離出許多亞胺糖組成分，諸如1-去氧野尻黴素(1-deoxynojirimycin)(DNJ)、蕎麥鹼(fagomine)及N-甲基-DNJ。亞胺糖的化學結構與單醣的化學結構相似，其主要是具有5至6員環的多羥基雜環。Mulberry leaves have a long history of medicinal use in Asian countries, especially China. In recent years, phytochemists have isolated many imino sugar components from mulberry leaves, such as 1-deoxynojirimycin (DNJ), fagomine and N-methyl-DNJ. The chemical structure of imino sugars is similar to that of monosaccharides, which are mainly polyhydroxy heterocycles with 5- to 6-membered rings.
已證實來自桑葉之亞胺糖組成分對α-葡萄糖苷酶I與II展現出一定的抑制活性，其中DNJ顯示出最強的活性。進一步的藥理學實驗揭示DNJ作用於黑素細胞而抑制TYR的成熟過程，其導致黑色素的生成低減。(Genji Imokawa，藉由差異式碳水化合物加工抑制作用對培養惡性黑素瘤細胞的TYR中黑色素生成所必要之碳水化合物性質分析。The Journal of Investigative dermatodiy，1990，95(1)：39-49；Ju Young Park，Hyunjung Choi，Jae Sung Hwang，Junoh Kim，Ih-Seop Chang，藉由pH敏感性脂質體遞送至HM3KO黑素瘤細胞之N-醣化抑制劑的增強脫色效果，Journal of Cosmetic Science，2008，59:139-150。)It has been confirmed that the imino sugar component from mulberry leaves exhibits certain inhibitory activity on α-glucosidase I and II, and DNJ shows the strongest activity. Further pharmacological experiments revealed that DNJ acts on melanocytes to inhibit the maturation process of TYR, which leads to a decrease in the production of melanin. (Genji Imokawa, analysis of carbohydrate properties necessary for melanogenesis in TYR cultured malignant melanoma cells by differential carbohydrate processing inhibition. The Journal of Investigative dermatodiy, 1990, 95(1): 39-49; Ju Young Park, Hyunjung Choi, Jae Sung Hwang, Junoh Kim, Ih-Seop Chang, Enhanced decolorization effect of N-glycation inhibitor delivered to HM3KO melanoma cells by pH-sensitive liposomes, Journal of Cosmetic Science, 2008 , 59:139-150.)
有許多含有白桑葉萃取物的市售補充劑(呈各種形式)。There are many commercially available supplements (in various forms) containing white mulberry leaf extract.
已知白桑葉萃取物會： ․支持健康糖位準與血液循環 ․改善整體消化健康 ․透過管理食慾與減少嗜食渴求來降低葡萄糖位準及穩定體內血糖 ․透過幫助控制您的食慾、嗜糖渴求及其吸收來支持健康減重。White mulberry leaf extract is known to: ․ Supports healthy sugar levels and blood circulation ․ Improve overall digestive health ․ Reduce glucose level and stabilize blood sugar in the body by managing appetite and reducing cravings ․ Support healthy weight loss by helping control your appetite, sugar cravings and absorption.
為了生產此等補充劑，必須提供一白桑葉萃取物之調配物，其再併入至所欲之最終市場產品。In order to produce these supplements, it is necessary to provide a blend of white mulberry leaf extract, which is then incorporated into the desired final market product.
亦有市售的白桑葉萃取物之調配物(諸如，來自DSM營養品有限公司的Reducose® 1%與Reducose® 5%)。There are also commercially available white mulberry leaf extract formulations (such as Reduceose ® 1% and Reduceose ® 5% from DSM Nutrition Co., Ltd.).
由於白桑之葉萃取物的重要性，存在此一萃取物之經改良調配物的需求。Due to the importance of the white mulberry leaf extract, there is a need for an improved formulation of this extract.
白桑葉萃取物的問題在於強吸濕性。此係例如對調配物的流動性有負面影響。流動性係粉末狀調配物之一相當重要的性質。The problem with white mulberry leaf extract is its strong hygroscopicity. This system, for example, has a negative impact on the fluidity of the formulation. Flowability is one of the very important properties of powdered formulations.
現今發現當白桑之葉萃取物與特定(高用量)之麥芽糊精(及任擇其他成分)一起調配時，所得之粉末的流動性係顯著改善。It has now been found that when the white mulberry leaf extract is blended with specific (high dosage) maltodextrin (and optional other ingredients), the fluidity of the resulting powder is significantly improved.
因此本發明涉及一種粉末狀調配物(PF)，包含 (i) 一白桑樹之葉萃取物及 (ii)以該粉末狀調配物的總重量計至少50重量%(wt-%)的麥芽糊精。Therefore the present invention relates to a powdered formulation (PF) comprising (i) Leaf extract of a white mulberry tree and (ii) At least 50% by weight (wt-%) of maltodextrin based on the total weight of the powdered formulation.

以下範例用於例示本發明。 範例 範例1The following examples are used to illustrate the invention. example Example 1
200克的Reducose 5%(來自DSM營養品有限公司)與1800克的麥芽糊精在雙作用式轉鼓機(篩子:0.5毫米)中混合。200 g of Reduceose 5% (from DSM Nutrition Co., Ltd.) was mixed with 1800 g of maltodextrin in a double-acting drum machine (sieve: 0.5 mm).
混合時間為5分鐘且溫度為20°C(濕度：50%RH)。The mixing time is 5 minutes and the temperature is 20°C (humidity: 50%RH).
然後所得的粉末狀調配物就流動性進行測試。此係透過測定脫附與吸附來完成。此係使用Aqualab蒸氣吸附分析儀執行動態蒸氣吸附(DVS)測試來完成。The resulting powdered formulation was then tested for fluidity. This is done by measuring desorption and adsorption. This system uses Aqualab vapor adsorption analyzer to perform dynamic vapor adsorption (DVS) test to complete.
靜態或平衡等溫的DVS方法係由下述構成：在樣品暴露於不同控制濕度下追蹤樣品重量變化。The static or equilibrium isothermal DVS method consists of the following: the change in sample weight is tracked when the sample is exposed to different controlled humidity.
將樣品在每個濕度下保持一預設的時間區間、或直到已達穩態重量變化，其目標係該樣品水活性與該控制濕度之間達到平衡。The sample is maintained at each humidity for a preset time interval, or until a steady-state weight change has been reached, the goal is to reach a balance between the water activity of the sample and the controlled humidity.
記錄重量變化對時間的資料，允許來測定每個濕度位準的吸附動力學。 有效相對濕度 = aw X 100 (即0.1 aw = 10% RH)Recording the weight change versus time data allows to determine the adsorption kinetics of each humidity level. Effective relative humidity = aw X 100 (i.e. 0.1 aw = 10% RH)
