In order to examine the nutritional value of prickly pear(Opuntia humifusa), contents of ash, protein, fat, minerals and vitamins were determined on freeze-dried stem, fruit, seed and root from plants harvested in autumn. The average moisture contents for stem, fruit, seed and root were 67~87%. Crude ash content determined on dry weight basis was 2~3%. Crude protein existed mostly in seed(2.95%) and root(2.37%). Crude fat was detected mainly in seed(4.49%). Contents of major minerals(mg/100 mg dry weight) was generally higher in stem. Ca in stem(4,142.30) and fruit(2,790.86) were much higher than in seed(43.37). P in stem, seed and fruit were 448.19, 263.20 and 161.59, respectively. Stem also displayed more abundant Mg(1,110.86), Zn(35.62) and Mn(37.07). However, fruit contained higher amounts of Fe(13.38) and Se(0.15). Vitamin A was negligible in all plant parts. Vitamin E contents in fruit and stem were 1.78 mg and 1.22 mg/mg dry weight, respectively. Vitamin C was detected mostly in fruit(445.40) and stem(260.94). Use of a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide-based microtiter assay of cell viability demonstrated an anti-proliferative effect of O. humifusa extract on the MCF-7 estrogen-dependent human breast cancer cell line.

Functional properties of mucilage and pigment extracted from Opuntia ficus-indica var. saboten were determined at various temperatures, pHs and alcohol concentrations. The crude mucilage extracted from pickly pear showed pH 4.2, 0.14% total acidity and 8.1% total soluble solid content(w/w, wet basis). Polysaccharide was purified from mucilage extract by isopropanol precipitation. Intrinsic viscosity of polysaccharide was 18.1dl/g and decreased with increasing KCl concentration. Relative viscosity and color stability of mucilage extract were determined with capillary viscometer and spectrophotometer at 534nm, respectively. In additions of 1~20%(v/v) ethanol, the red pigment of mucilage extract was very stable, but relative viscosity, increased gradually. For heating above 7$0^{\circ}C$, the stability of red pigment decreased drastically, but rheological property of mucilage was not changed. During storage, the red pigment was extremely unstable at above pH 8.3. At both pH 3.0 and pH 4.2, the red pigment was the most stable at 4$^{\circ}C$ for 18 days. In the case of storage at 37$^{\circ}C$, pigment of mucilage extract at pH 3.0 was destroyed more quickly than that at pH 4.2. Natural mucilage extract(pH 4.2) showed the good stability of red pigment at 3$0^{\circ}C$ for 10 days.

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.

Opuntia humifusa, member of the Cactaceae family, was previously demonstrated to have radical scavenging, anti-inflammatory and anti-proliferative effects in in vitro models. It was suggested that O. humifusa could function in the prevention of carcinogenesis. To investigate the in vivo chemopreventive effect of O. humifusa, mice were fed a diet containing either 1% or 3% following 7, 12-dimethylbenz[a] anthracene (DMBA) and 12-O-tetradecanoylphorbol-13-acetate (TPA) induction of skin carcinogenesis. Significant decrease in the numbers of papilloma and epidermal hyperplasia were observed in mice fed with O. humifusa, compared to the control group. O. humifusa also upregulated high total antioxidant capacity and level of phase II detoxifying enzyme such as superoxide dismutase and glutathione S-transferase activity in the skin. Lipid peroxidation activity level was measured in skin cytosol and significantly inhibited in 3% OH fed group compared to the control group. These results suggest that O. humifusa exerts chemopreventive effects on chemical carcinogenesis in mouse skin and that prevention effects are associated with reduction of oxidative stress via the modulation of cutaneous lipid peroxidation, enhancing of total antioxidant capacity especially in phase II detoxifying enzyme system and partial apoptotic influence.

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 humifusa known as the Eastern prickly pear have been used as a treatment of burns, diarrhea, asthma, rheumatism, gonorrhea, and diabetes in alternative medicine. O. humifusa is widely cultivated in the middle and southern provinces of Korea and distributed in North America. The aim of this study is to investigate anti-diabetic effect of O. humifusa stem (OHS) water or 80% MeOH extract using 3T3-L1 adipocytes and db/db mice animal models. OHS 80% MeOH extract at a dose of $250{\mu}g/ml$ significantly increased the glucose uptake and lipid accumulation compared with the control in 3T3-L1 adipocytes. Blood glucose, plasma total cholesterol and triglyceride levels were significantly reduced by oral treatment of OHS 80% MeOH extract (200 mg/kg BW) for 6 weeks in db/db mice. Also, the oral treatment of OHS 80% MeOH extract slightly changed the plasma insulin and insulin resistance levels in db/db mice, but were no significance in comparison to control. Glucose transporter(GLUT)4 expressions of adipose tissue and muscle were significantly increased more than that in the control. Therefore, these results suggest that OHS 80% MeOH extract inhibits the blood glucose level through regulation of lipid profile, insulin resistance, and GLUT4 expression in db/db mice and its diabetic effect is effective more than water extract.

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.
