• 説明

  The main source of curcumin is the root of Zingiberaceae Curcuma aromatica, rhizome of Curcuma longa (Jiang Huang), Curcuma zedoaria, and Acorus calamus. Among them, Jiang Huang contains about 3–6% curcumin. The traditional Chinese medicine, Jiang Huang, is the root tuber of perennial herbaceous plant Curcuma longa L. of family Zingiberaceae. It was firstly recorded in the “Tang materia medica” (Xin Xiu Ben Cao). It is pungent, bitter, and warm and enters the liver and spleen meridians. It activates the blood, moves qi, dredges meridians, and alleviates pain. In India and other Asian countries, Jiang Huang has more than 6000?years of application history. In Japan, Jiang Huang has a long history of health care, and the people of Okinawa Island regarded Jiang Huang as a holy tribute to the emperor. Jiang Huang mainly comes from Taiwan, Fujian, Guangdong, Guangxi, Yunnan, and Tibet of China and other regions in East Asia and Southeast Asia. It grows in warm and humid climate and sunny environment with abundant rainfall and fears cold frost, drought, and flood. At present, Chinese Pharmacopoeia only included Jiang Huang and Yu Jin which contains curcumin, while curcumin is not included.

• 化学的特性

  orange crystalline powder

• 物理的性質

  Appearance: orange-brown crystalline powder and tastes a little bitter. It will turn into reddish brown in alkaline solution and yellow in neutral and acidic solution. It has strong stability against the reducing agent. It has excellent pigmentation which is not easy to fade. It is sensitive to light, heat, and iron ion. When PH is greater than 8, curcumin turns from yellow to red, which can be used as a pH indicator.
  Solubility: insoluble in water or diethyl ether and soluble in ethanol, propylene glycol, acetic acid, and alkali solution.
  Melting point: about 183 °C.

• 使用

• 定義

  ChEBI: A beta-diketone that is methane in which two of the hydrogens are substituted by feruloyl groups. A natural dyestuff found in the root of Curcuma longa.

• 一般的な説明

  Orange-yellow needles.

• 空気と水の反応

  Slightly soluble in hot water .

• 反応プロフィール

  Curcumin is sensitive to light and changes in pH. Curcumin may react with oxidizing materials.

• 生物活性

  Antitumor, anti-inflammatory and antioxidant agent. Downregulates expression of reactive-oxygen-generating enzymes (cyclooxygenase, lipoxygenase, iNOS), TNF α , IL-1, IL-6, PKC, EGFR, NF- κ B, I κ B kinase and more. Upregulates expression of PPAR γ , p53, Nrf2. Also displays antimicrobial, antidiabetic neuro- and cardioprotective properties in vivo .

• 作用機序

  Curcumin, the active component of turmeric (Curcuma longa), has been regarded as an anti-inflammatory and antioxidant agent . Particularly, it can scavenge reactive oxygen species, such as hydroxyl radicals, superoxide anion radicals, and nitrogen dioxide radicals. Additionally, it serves as an anti-inflammatory by down-regulating the production of pro-inflammatory cytokines (e.g., IL-1 and TNF-α) and inhibiting the activation of specific transcription factors (e.g., NF-κB and AP-1). Curcumin also demonstrates antiproliferative properties. Specifically, it inhibits UV radiation-induced skin cancer in SKH-1 hairless mice and reduces UVB-induced matrix metalloproteinase-1/3 expression in human dermal fibroblasts via MAPK-p38/JNK pathway suppression.

• 臨床応用
