Açaí (Euterpe oleracea) emerged as a source of herb has a long history in South America, which was approved by the Ministry of Health used in China and it has been introduced planting in Guangdong and Taiwan. This article summarized applied history of Açaí and its present status in China. Did theoretical study on the Chinese herbal properties of Açaí based on the Chinese traditional philosophical culture to analysis the function and symptom preliminary, combining with used for medical recordation, chemical component, biological activity. It is aiming at establishing the theoretical foundation for the application under the guidance of TCM theory.

To investigate the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the temperature tendency animal behavior and intrinsic biochemical indexes, such ascyclic nucleotides and metabolic level, in mice with deficiency-heat and deficiency-cold syndrome, in order to study the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling. KM mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given thyroid tablet solution(160 mg·kg~(-1)), the mice in deficiency-cold group were given hydrocortisone solution(25 mg·kg~(-1)) through gastric perfusion every afternoon for 14 days, and each administration group was given the corresponding drug. The temperature tendency, cyclic nucleotides and metabolic level of animals were measured after the experiment. The Açaí alcohol extract was consistent with the Açaí powder, with a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinnamomi Cortex, with a regulatory effect on the deficiency-cold model mice. In this study, based on the parable theory of traditional Chinese medicine's properties and tastes, property of alcohol extract of Açaí was cool, while the property of oil and water extract were warm, the alcohol extract of Açaí was the material basis of Açaí cold medicine by the methods of homogeneous comparison and heterogeneous disproval.

To investigate the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling by observing the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the neurotransmitter, endocrine hormone and immune factor level in mice with deficiency-heat and deficiency-cold syndrome. KM male mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, and deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given with thyroid tablet solution(160 mg·kg~(-1)), and the mice in deficiency-cold group were given with hydrocortisone solution(25 mg·kg~(-1)) by intragastric administration every afternoon for 14 days. The mice in each administration group received corresponding drug. The neurotransmitter, endocrine hormone and immune factor levels in the mice were measured after the experiment. The Açaí alcohol extract, consistent with the Açaí powder, showed a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinna-momi Cortex, showing a regulatory effect on the deficiency-cold model mice. In this study, on the basis of proving that Açaí was was cool in property, it also revealed that alcohol extract of Açaí was cool while oil and water extract were warm in property based on the effect of Açaí on neuro-endocrine-immune network. The results suggested that the medicine property of Açaí was the result of the comprehensive action of the resolution components with different properties, and the alcohol extract of Açaí was proved as the material basis of Açaí cold medicine by using the methods of homogeneous comparison and heterogeneous disproval.

OBJECTIVETo study the protective effect of Acai berries(Euterpe oleraceae) on chronic alcoholic hepatic injury in rats and their mechanism.
METHODWistar rats were fed for 1 week and randomly divided into blank group, model group, Dongbao Gantai group, Acai 1.6, 0.8, 0.4 g . kg-1 groups. The blank group was given distilled water, and the other groups were orally given 56% white spirit (Erguotou) for eight weeks at the dosages of 8 mL . kg-1 in the 1st week, which increased by 0.1 mL week by week till to 15 mL . kg-1, in order to establish the chronic hepatic injury model, and observe the effect of Acai berry freeze-dried powder on hepatocyte membrane permeability, liver lipid peroxidation, changes in inflammatory cytokines and pathological changes in hepatocytes.
RESULTAcai berries could significantly reduce serum ALT and AST(P<0.05), MDA(P<0.05), TG(P<0.05) and serum TNF-α and IL-6(P <0.05) and increase GSH and SOD(P <0.05). According to liver histopathological observation, livers in the model group were dominated by steatosis, some livers suffered spotty necrosis and inflammatory cell infiltration; The positive drug and Acai groups showed different changes in pathologic changes in rat livers.
CONCLUSIONAcai berries show s specific protective effect on alcoholic hepatic injury. Its mechanism may be correlated with the inhibition of such inflammatory factors as TNF-α and IL-6.
