Prickly pear juice(PPJ) extracted from prickly pear fruit (Opuntia ficus-indica)was used as raw material for the production of alcoholic beverages. Prickly pear juice (PPJ) had 0.88 oBrix of soluble solid, pH 3.96 and 0.14% of total acidity. Alcohol fermentation of 25% PPJ including 22 oBrix of sugar and 1$\times$106 of inoculum was suitable for alcohol fermentation indicating the rapid decrease of sugar content. The 22 oBrix of sugar in PPJ (25%)GJ (50%) mixture was changed to 6.5 oBrix after fermentation at 3$0^{\circ}C$ for 7 days. The alcohol content was 9.2% (w/v). PPJ (70%)/GJ (30%) mixture produced alcoholic beverage with 6.9% alcohol content resulting in the gradual decrease of soluble for 7 days. On the other hand, PPJ (50%)/GJ(50%) mixture carried out completely the alcohol fermentation at 22$^{\circ}C$ for 6 days and enhanced the red color of alcoholic beverages.

The objective was to verify biological activities of fruit and stem of prickly pear(Opuntia ficus indica L. var, saboten Makino). We have determined inhibitory activities on enzymes, such as dopamine ${\beta}$-hydroxylase(DBH), monoamme oxidase A and B(MAO-A, B), and antioxidant activity, in vitro. We purchased dried stem powder and lyophilized fruit powder of prickly pear from CheJu Island, and prepared the extracts with 80% of methanol. The fruit extract showed stronger inhibitory effects on MAO-A and -B and antioxidant activity compared. to the stem extract, on fractionation with hexane, ethyl acetate, butanol and water. Both the stem and the fruit extracts with ethyl acetate showed stronger enzyme inhibitory and antioxidant activities than other extracts. Now we are isolating active principles from both ethyl acetate extracts.

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.

Prickly pear(Opuntia ficus-indica var. saboten Makino, Cactaceae) is a tropical or subtropical plant, which is widely used as folk medicine for burned wound, edema and indigestion. Screening on the biological properties of the fruits(OFS-Fr) and stems(OFS-St) of the plant was carried out to prove the pharmacological significance. By hot plate and acetic acid-inducing writhing methods, significant analgesic effects of OFS-Fr and OFS-St were found in mice and anti-edemic effect was observed in carrageenin-induced inflammatory rats. However, the extracts showed no significant actions on central and autonomic nervous system and blood circulatory system, which imply no toxic effects to animal.

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.

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.

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.

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.
