Geranium genus clasification Within the classification of Geranium genus are accepted 423 species, distributed in three subgenuses: Erodioidea, Geranium and Robertium. It is proba bly that the species of this genus that growing in the State of Hidalgo possess a similar biological activities and metabolites. Tannin-protein complexes in the gastrointestinal tract provide persistent antioxidant ac tivity. One of the major components in Geranium species isgeraniin (4) [10] described by its discov erer as a crystallizable tannin. The corilagin (5) [15] is a derivative of geraniin, which has presented antimicrobial activity among other activities [16]. Different species of geraniums and its relevant compounds The specie Geranium macrorizum presented a significant hypotensive activity in anesthe tized cats [17], plus antioxidant activity. Of this specie germacrone (6) was isolated which is considered a precursor of pheromones. Also infusions and decoctions prepared from leaves of this geranium: Robert herb or red Robin, are described as anti-hyperglycae miant and commonly used in Portuguese herbal medicine [18]. From flowers of Geranium sylvaticum was isolated 3-O-(6-O-acetyl--D-glucopyranoside)-5- O--D-glucopyranoside of malvidin (7) [21]. The methanolic extract of Geranium pratense inhibited the action of the amylase enzyme in mouse plasma, isolated for first time the 3-O-(2-O-galloyl) --D-glucopyranoside myricetin(9) [22]. Geranium pusillum, commonly known as Small-flowered Cranesbill or (in North America) small Geranium, contains1-O-galloyl-3,6-hexahidroxibifenil-D-galactopyranoside (11) (pusi lagin) a polyphenolic compound extracted from aerial parts [26]. The aqueous ethanolic ex tract of Geranium wallichianum showed antibacterial activity against Staphylococcus aureus [27] and the study of the chemical constituents of the whole plant has resulted in the isola tion and characterization of six compounds. Geranium caespitosum produces neohesperidoside (12) able to potentiate 10 to 100 times the action of drugs such as ciprofloxacin, norfloxacin, berberine and rhein, against bacterias such as S. It is clinically used to treat the arthralgia due to wind-dampness, anaesthetization and muscular constriction. Also, has shown that roots contain a substance that is extracted with water and can be a biological mechanism to control bacteria (Ralstonia solanacearum) which attacks potatoes [31]. In Geranium mexicanum an antiprotozoal activity was assayed from its roots, where the most active compound founded was the flavan-3-ol-(-)-epicatechin (14), showing moderate activity (+)-catechin (14a), tyramine (15) and 3-O--D-glucopyranoside of -sitosterol [33]. The use of other geranium species also has been reported a hypoglycemic, antihypertensive and cholesterol-lowering effect. However, scientific evidence does not exist in any literature to corroborate these targets or any other. Plant material Specimen of Geranium schiedeanum was collected at Epazoyucan Municipality, in Hidalgo State, Mxico, during June 2009. Extraction and purification Air-dried aerial parts (1 kg) were extracted acetone-H O 7:3 (20 L) by maceration for 7 days. Throughout these two weeks rats were supplied with food and water ad libitum, exposed to a 12 h light-dark cycle and giv en intraperitoneally a single necrogenic dose of thioacetamide (6. The dose of thioacetamide was chosen as the highest dose with survival above 90% [36,37]. Each experiment was performed in duplicate from four different animals and followed the international criteria for the use and care of experimental animals outlined in The Guiding Principles in the use of Animals in Toxicology adopted by the Society of Toxicology in 1989. Rats were sacrificed by cervical dislocation and samples of liver were obtained and processed as previously descri bed. Blood was collected from hearts and kept at 4 C for 24 h, centrifuged at 3000 rpm for 15 min, and serum was obtained as the supernatant. Liver damage induced by xenobiotics is characterized by the release in serum of hepatic en zymes due to necrosis of hepatocytes. Our results showed that Gs extract significantly reduced the level of liver injury. Effect of Gs pre-treatment on aspartate aminotransferase activity in serum of rats intoxicated with one sub lethal dose of thioacetamide. Differences against the respective control are expressed as (a) and differences due to Gs extract are expressed as (b) p<0. Conclusion There is evidence that free radicals play a critical role in certain pathological conditions such as some cancers, multiple sclerosis, inflammation, arthritis and arterosclerosis [43]. For this reason, some research objectives directed toward the development or discovery of these compounds catchers of these radicals. The phytochemical study of Geranium shiedeanum led to the isolation of hydrolysable tannins, well known as potent antioxidants: gallic acid, acetonylgeraniin and ellagic acid and a lesser proportion of kaempferol glycoside flavonoid (3-O--L-arabinofura noside-7-O--D-rhamnoside de Kaempferol), notably is the first time discloses these com pounds in the genus. The pre-treatment with the crude extract in the model of thioacetamide-induced hepatotox icity in rats, decreased and delayed liver injury by 66% at 24 h. This result suggests that Gs extract may be used as an alternative for reduction of liver damage. However further investigation on the acute toxicity and on the mechanism of the hepatoprotective effect of the plant species needs to be carried out.

Introduction Epidemiological studies on the relationship between dietary habits and disease risk have shown that food has a direct impact on health. Indeed, our diet plays a significant role in health and well-being, since unbalanced nutrition or an inadequate diet is known to be a key risk factor for chronic age-related diseases [1]. An example that illustrates this fact is the pro tective effect of the so-called Mediterranean diet. The lower occurrence of cancer and cardio vascular disease in the population located around the Mediterranean sea has been linked to the dietary habits of the region, in which the components of the diet contain a wide array of molecules with antioxidant and antiinflammatory actions [2]. Many diseases with a strong dietary influence include oxidative damage as an initial event or in an early stage of disease progression [3]. In fact, Western diets (typically dense in fat and energy and low in fiber) are associated with disease risk [4]. Therefore, dietary modifi cation, with a major focus on chronic age-related disease prevention through antioxidant in tervention, could be a good and cost-effective strategy [5]. The intake of whole foods and/or new brand developed functional foods rich in antioxidants would be suitable for this pur pose.
