2. Antibacterial and antiviral: ethanol and water extract of the cactus on Bacillus subtilis, Streptococcus, alpha hemolytic streptococcus, Streptococcus pneumoniae, Staphylococcus aureus and other Gram-positive bacteria was significantly inhibited role, the effect of E. coli and other gram-negative bacteria is relatively somewhat less, on Rhizopus nigricans, Aspergillus fungi effect is very small, the antibacterial activity of water extract them from the dry powder of the flowers is the best [5]. Cactus extract can inhibit the DNA and RNA [6] of herpes simplex virus typeI, the horse herpes virus, influenza virus and HIV (HIV-1) of the replication.

3. Down glucose: fresh actus 30g/kg orally, 7 hours later, can reduce blood glucose in normal mice. Dry cactus the decoction alcohol sediments 22.5g/kg gavage, 7 hours later, reducing blood glucose of normal mice [7]. Cactus 0.75% of acidic water extract are given intraperitoneal injection of 200mg/kg, 400mg/kg, six days in a row, can significantly reduce the blood glucose of normal mice alloxan-induced diabetic mice, the hypoglycemic effect follows a dose relationship [8]. Cactus polysaccharide 150mg/kg, 200mg/kg, 250mg/kg orally, can reduce the blood glucose [9] in diabetic mice,

4. Lowering blood pressure: the pectin extracted from cactus, 3% content added to the feed containing 0.25% cholesterol and  feed guinea pigs, can reduce LDL levels in the blood, liver free and bound cholesterol are down 40 % and 85%. the mechanism to lower plasma cholesterol levels may be the same to bile acid binding resin, it could increase bile acid excretion, and block the enterohepatic circulation [10]. Cactus powder 3g /day, 6g /day, 9g / day administered orally for 21 days, can significantly reduce the serum cholesterol of experimental hyperlipidemia in, LDL cholesterol and atherogenic index, triglyceride esters, and its lipid-lowering effects follows dose-relationship [11].

5. Anti-gastric ulcer: cactus alcohol extract of 32g/kg and 8g/kg gavage in rats has significant therapeutic effect on stomach gastric ulcer under stress type, indomethacin, pyloric ligation, and can certainly improve the E2 content [12] of gastric juice prostaglandin. The Cactus aqueous extract ethanol sediments 17.2g/kg, 8.6g/kg and 4.3g/kg administered orally, can inhibit gastric ulcer caused by reserpine in mice to inhibit gastric acid secretion, reduce gastric acidity, as well as  reduce the activity of pepsin the same time, and keep the prostaglandin E2 secretion balance, promote healing of ulcers [13].

6. Cancer: cactus fruit extract can inhibit cancer cell proliferation of cervical cancer, ovarian cancer and bladder cancer, the role equall to the ovarian cancer prevention drug 4-N hydroxy-dimensional methylamine, its inhibitory effect on tumor cell growth related with apoptosis in cancer cells and cancer cells extending residence time [14] in the G phase. Cactus5in flavonoids can increase the concentration of intracellular calcium, and interfere the interleukin-2 expression [1], of the conversion to S phase of human T-cell related.

7. Antioxidant, anti-aging: cactus decoction of 1.5g crude drug/mL and 0.75g of crude drug/mL in vitro can significantly inhibit the malondialdehyde ( MDA) generation in mouse and rat liver homogenate induced by CCl4 , 30g crude drug/kg, 60g crude drug / kg administered orally can significantly reduce the content of MDA caused by CCl 4  in the mouse liver tissue [16]. Cactus powder 1.25g / 2.5g /day and 5g / day administered orally, significantly reduce the MDA content in serum and serum superoxide dismutase (SOD) activity is certainly higher than the control one. The cactus can certainly prolong half the time of death of Drosophila, the average life expectancy and maximum life [17]. Cactus polysaccharide 200mg/kg, 400mg/kg ig can significantly reduce the activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT) in hyperlipidemia rat liver, significantly reduce the heart MDA content, accelerate the anti-O2 - and SODactivity to strengthen the heart, its antioxidant effects may be related to clear the body of oxygen free radicals and lipid peroxidation [18].

8. Immune Enhancement: cactus extract 1.25g/kg and 2.5g/kg orally for 10 consecutive days, significantly increase the spleen index, peritoneal macrophages of phagocytosis and peripheral blood WBC count, has a certain role to enhance immune function[19]. Cactus polysaccharide200mg/kg, 400mg/kg gavage, a significant increase in immune suppression by cyclophosphamide-induced of murine macrophage phagocytosis rate, white blood cells, slowing the immunosuppressed mice red blood cell count, increasing pathological, to reduce the number of platelets and improve immunity to inhibit the hemolytic activity of the activation pathway of mouse complement bypass, can enhance immune suppression of non-specific immune function in mice [20].

9. The role of acute liver injury: cactus polysaccharide 200mg/kg, 400mg/kg orally administered for 30 days, can significantly inhibit the serum ALT AST and liver content of MDA increasing of CCl 4-  induced mice liver injury, liver can reduce the activity of SOD, glutathione S-transferase, glutathione peroxidase and imrpove the glutathione content significantly. And reduce the pathological changes of liver tissue, it tells that cactus polysaccharide has a protective effect on CCl4 induced liver injury in mice. Antioxidant capacity of glutathione system [21, 22] may be related.
