This study done to investigate the hypocholesterolemic effect of ow dietary fiber in a high cholesterol diet in aspect of cholesterol absorption and excretion using Sprague Dawley rats. After feeding diets containing 0.5% cholesterol and 5% tangerine pulp, sea tangle or prickly pear cactus for four weeks, we measured the levels of plasma and liver cholesterol and triglyceride, fecal neutral sterols and fecal radioactivity after ingestion 14(sup)C-cholesterol. We also examined platelet aggregation and histological change in liver tissues in association of hypercholesterolemia. The liver to body weight ratio was significantly(p<0.01) lower in rats fed prickly pear cactus than in other groups. The levels of plasma total cholesterol, LDL-cholesterol and triglyceride were decreased significantly(p<0.01) in the prickly pear cactus group compared with the control, while there was no difference in the liver levels of total cholesterol and triglyceride among groups. Fecal corprostanol and cholesterol were significantly(p<0.01) higher groups of control and prickly pear cactus compared to the other two groups. Radioisotope excretion after ingestion of 14(sup)C-cholesterol was higher in the control group than in tangerine pulp group or sea tangle group, with the highest in prickly pear group. Radioisotope excretion was the highest during the 2nd and 3rd days in all groups. Hematocrit and platelet aggregation were decreased in all fiber groups compared to the control, but not statistically different. Microscopic examination showed that cholesterol diet cause a fat accumulation in the liver and prickly pear cactus decreased the fat accumulation. Result indicates that prickly pear cactus has hypocholesterolemic effect by decreasing absorption and increasing excretion of cholesterol, thereby protective effect on fatty liver. Control group fed diet containing high cholesterol and low fiber seems to have a self control system in cholesterol absorption and excretion preventing hypercholesterolemia.

We investigated dietary effects of prickly pear cactus (Opuntina ficus-indica) on plasma lipids, platelet aggregation (PA), hemolysis, plasma TBARS and liver enzymes. Twenty eight volunteer diving women in Jeju island had daily 20 g cactus tea containing 27% prickly pear cactus (PPC) powder for 4 weeks, and data for the study subjects were analyzed, on the basis of diagnostic criteria for blood pressure (BP)(${\geq}$ 140/90 mmHg), plasma cholesterol (${\geq}$ 200 mg/dL) and triglyceride (${\geq}$ 150 mg/dL). The subjects with higher BP had higher plasma total cholesterol (TC) and triglyceride (TG) concentrations than those with normal BP. Those with higher TC also had higher TG. Subjects with normal BP or normal TC had higher initial slope of PA than their higher counterpart in BP and TC. PPC intake decreased plasma TG in those with higher BP. PPC intake significantly decreased the elevated initial slope in groups with normal BP, TC, and TG. Hemolysis after PPC intake decreased significantly in all the subjects and plasma TBARS decreased in the subjects with higher plasma TC and higher TG. Glutamic-oxaloacetic transaminase (GOT) significantly increased and total bilirubin significantly decreased in all the subjects after PPC intake. The present study with diving women showed that beneficial effects of short term intake of prickly pear cactus might differ depending on the subject conditions in term of blood pressure, and plasma lipids. However, long term usage of prickly pear cactus may provide preventive effects of cardiovascular diseases to all the population, presumably by hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids and soluble fiber.

Prickly pear(Opuntia ficus-indica var saboten Makino, Cactaceae) is widely used as folk medicine for burned wound, edema and indigestion. To confirm the hypolipidemic action of the extract from Cactus stem and fruit in dietary hyperlipidemic rats, variations of the lipid- or cholesterol-related components were investigated. As results these changes were significantly prevented by treatments with Cactus extracts. The effects of the extract of fruit was better than those of stem.

The extracts from stem and fruit of Cactus (Opuntia ficus-indica var. saboten Makino) were applied to confirm the antiatherosclerotic effects in subacute alcoholic hyperlipidemic rats. It was observed that several indications of hyperlipidemia were prevented or changed by the treatments of the extracts but activities of hepatic HMG-CoA reductase and alcohol dehydrogenase were not affected, which suggest that the extracts may promote the fecal excretion and delay the absorption of alcohol in hyperlipidemic rats.

Opuntia ficus-indica, commonly known as prickly pear cactus, is commercially grown as a food and medicinal plant in Jeju Island, Korea. The crushed pads and fruits of Opuntia ficus-indica were dried in a freeze-dryer and ground into flour to be used for food materials. The major components of proximate compositions were part of a nitrogen free extract. The major minerals were Ca (4391.2-2086.9㎎%), K (1932.1-2608.7㎎%), and Mg (800.6-1984.8㎎%). The major amino acid was glutamic acid, comprising 16.3% of total amino acids in fruit and 25.2% in pad. Dihydroflavonols were identified as (+)-trans-dihydrokaempferol and (+)-trans-dihydroquercetin. Citric acid methyl esters extracted from fruits showed inhibitory activities against monoamine oxidase-B. The presence of trimethyl citrate has been reported in other plants, but 1,3-dimethyl citrate and 1-monomethyl citrate have not been previously reported. The results of pharmacological efficacy tests, including serum biochemical and hematological parameters, autonomic nervous system, anti-inflammatory, analgestic activity, anti-diabetic activity, antithrombotic, anticoagulant, dopamine beta-hydroxylase, monoamine oxidase activity, hyperlipidemia, the respiratory system, antigastic, and anti-ulcerative actions indicate that the fruit and pad of the Opuntia ficus-indica are rich sources of food and medicinal materials.

To determine the antimicrobial and anti-inflammatory efficacy of Opuntia ficus-indica for chronic otitis, we evaluated the effects of topical applications of the methanol extracts with 20 cases of dogs which had chronic malignant otitis by pathogens with antibiotic resistance. The dogs had revealed recurrent symptoms of malignant otitis and were not treated by conventional therapeutic agents. However, in this study, the clinical cure rates of Opuntia ficus-indica was 75% and the average alleviation period was $1.21{\pm}0.42$ week, and the mean recovery period was $1.06{\pm}1.06$ week after the initiation of treatment. As the results of this study, topical Opuntia ficus-indica extracts was found to be highly effective for the treatment of chronic malignant otitis with clinical cure rates of 75% within 1.06 weeks of therapy. Further evaluation of Opuntia ficus-indica extracts will allow us to establish and to optimize the therapeutic strategy for the malignant otitis in veterinary practice, and the potential usefulness of this complementary treatment on recurrent infectious pathology.

Opuntia dillenii Haw의 열매를 시료로 하여 betacyanins의 온도에 따른 안정성과 N-propyl gallate, L-cysteine, ascorbic acid에 대한 농도별 항산화효과를 조사하였다. Betacyanins의 최대 흡광도는 $536{\sim}538\;nm$에서 일어났으며 $90^{\circ}C$에서 열처리 시간이 경과될수록 색소가 퇴색되면서 최대흡수파장이 자외선 영역으로 이동하는 현상을 나타냈다. Betacyanins는 열처리 온도에 대해 1차 반응 속도식에 따라 분해되었으며 $50^{\circ}C$에서 $90^{\circ}C$까지 열처리 했을때 반응 속도 상수가 $1.56{\times}10^{-3}$분에서 $71.91{\times}10^{-3}/min$분으로 증가하고 반감기가 444.23분에서 9.64분으로 감소하여 온도가 상승함에 따라 열안정성이 저하되는 결과를 보였다. 또한 betacyanins의 활성화 에너지는 10.94 kcal/mole로 나타났다. N-propyl gallate, L-cysteine, ascorbic acid를 $0.01{\sim}0.3%$ 내로 첨가하여 $50^{\circ}C,\;70^{\circ}C,\;90^{\circ}C$에서 betacyanins에 대한 항산화 효과를 비교한 결과 $70^{\circ}C$와 $90^{\circ}C$에서 미약한 항산화 효과를 보였으며 모든 온도에서 ascorbic acid는 $2{\sim}10$배 정도의 반감기를 증가시켜 항산화 효과가 뛰어난 것으로 나타났다.

본 연구는 재배지역별 보검선인장의 총 플라보노이드, 총 폴리페놀 함량과 6종의 phenolic acid, 19종의 flavonoids, 6종의 carotenoid를 함량분석하고 DPPH radical과 ABTS radical scavenging 활성을 측정하였다. 총 플라보노이드 함량은 남해에서 재배된 ON1 보검선인장이 65.32 mg(+)-catechin/g으로 가장 높게나타났고, 총 폴리페놀 함량은 제주에서 재배된 OJ1 보검선인장이 181.15 mg garlic acid/g으로 가장 높게 나타났다. 6개의 phenolic acid 중에서, protocatechuic acid는 전남 남해산인 ON1과 ON2가 유의적으로 높게 나타났으며, 4-hydroxybenzoic acid, chlorogenic acid 및 trans-ferulic acid는 ON2에서 가장 높게 나타났고, vanillic acid와 p-coumaric acid는 OJ4에서 가장 높은 함량을 보여 재배지역에 따라 페놀산 함량에 차이가 나타났다. 플라보노이드의 경우, quercetin, isorhamnetin, kaempferol은 OJ3 보검선인장에서 가장 높게 나타났으며 각각의 배당체에 대한 함량도 다양하게 나타났다. 보검선인장의 주요 carotenoid는 zeaxzanthin과 capxanthin으로 나타났으며 각각 93.83과 $128.08{\mu}g/g$ DW로 OJ1 보검선인장이 가장 높게 나타났다. DPPH radical과 ABTS radical scavenging 활성의 경우, 총 플라보노이드와 폴리페놀의 함량이 가장 높은 OJ1 보검선인장이 가장 높게 나타났다. 따라서 플라보노이드와 폴리페놀의 함량이 항산화 효과에 영향을 미치며, phenolic acid, flavonoid, carotenoid의 종류와 함량에 따라 항산화 효과가 다양하게 나타나는 것으로 판단된다.
