These areas have ample sunshine, high temperatures, rainy seasons, very suitable for turmeric’s growth.
2.姜黄主要化学成分：
Main chemical ingredients of turmeric
1）.姜黄素，Curcumin（化学名Chemical Name：1，7-Bis-<4-hydroxy-3-methoxyphenyl>-hepta-1,6-diene-3,5-dione），分子式Molecular FormulaC21H20O6，分子量Molecular Weight368.37，CAS: 458-37-7；）
2）脱甲氧基姜黄素，Demethoxycurcumin（化学名Chemical Name：1-<4-Hydroxyphenyl>-7-<4-hydroxy-3-methoxyphenyl>-hepta-1,6-diene-3,5-dione），分子式Molecular FormulaC20H18O5，分子量Molecular Weight338.35，CAS：24939-17-1）
3）.双脱甲氧基姜黄素，Bisdemethoxycurcumin（化学名Chemical Name：1,7-bis-<4-hydroxyphenyl>-hepta-1,6-diene-3,5-dione），
分子式Molecular FormulaC19H16O4，分子量Molecular Weight308.33，CAS：33171-05-0）
1）具有延缓衰老的作用。姜黄素具有很强的抗氧化作用，以消除体内有害的自由基，对OH自由基的消除率可达69%。姜黄素能提高肝组织均浆中多种抗氧化酶的活性，能使SOD、过氧化氢酶和谷光甘肽过氧化酶的活性分别提高约20%；姜黄素对胸、心、肾、脾等组织都有明显的抗氧化作用，使过氧化脂质（LPO）含量降低，从而延缓组织的老化。
Curcumin has strong antioxidant capacity for retarding aging. It caneliminateharmful free radical inside human body. The eliminating rate for OH free radical can achieve 69%. Curcumin can both improve a lot of antioxidases’ activity of hepatic tissue plasm and increase the activity of SOD, catalase or GuGuangGan peptide peroxidase respectively to around 20%; curcumin has obvious antioxidant function for the tissues of chest, heart, kidney, spleen etc, reducing the content of lipid peroxidation (LPO), so that the tissues’ aging can be retarded.
2）抑制DNA不正常增生，达到预防癌症功效
Inhibition of DNA abnormal hyperplasia,cancer prevention effectiveness to achieve
姜黄素对于多种癌症有预防作用，包括皮肤癌、肠癌、十二指肠癌、肾癌、摄护腺癌及口腔癌。
Curcumin can prevent many types of cancer, including skin cancer, colon cancer, duodenal cancer, renal cell carcinoma, prostate cancer and oral cancer.
