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.

The fruit and stem of Opuntia ficus-indica var. aboten (OFS), a native plant of Jeju Island, are considered a safe food source. Moreover, stem extracts have been previously reported to possess a variety of biological effects (e.g. anti-inflammatory and anti-oxidant, including the ability to partially ameliorate cognitive impairment), suggesting that this plant may have utility as a functional food. The present study investigated whether fermentation by lactic acid bacteria enhances the biological effects of OFS extracts. The acetylcholinesterase (AChE) inhibitory activity of fermented or non-fermented OFS extracts was evaluated, and the content of marker components dihydrokaempferol (DHK) and quercetin-3-methyl ether (3-MeQ) was analyzed using high-performance liquid chromatography. Fermented (relative to non-fermented) OFS extracts exhibited improved AChE inhibitory activity ($IC_{50}=28.35 mg/mL$), with AChE inhibitory activity resulting from fermentation by L. plantarum ($IC_{50}=12.56mg/mL$) exceeding that resulting from fermentation by L. fermentum ($IC_{50}=17.71mg/mL$). Furthermore, fermented (relative to non-fermented) OFS extracts exhibited a 16.7 % increase in DHK content, and 3-MeQ content of OFS extracts fermented by L. plantarum and L. fermentum increased by 28.6 % and 21.4 %, respectively. Therefore, OFS stem extract AChE inhibitory activity, as well as DHK and 3-MeQ content, was enhanced by fermentation with Lactobacillus spp. This suggests that fermented OFS extracts may contribute to prevention or improvement of cognitive impairment. These data are anticipated to be useful in the development of enhanced-efficacy OFS products.

The purpose of this study was to determine the possibility of using Opuntia ficus-indica as a natural health food source. To accomplish this, the contents of general and antioxidative nutrient contents of Opuntia ficus-indica were measured. The carbohydrate, crude protein, crude fat and crude ash were 66.79%, 5.51%, 9.89% and 9.29%, respectively. The calorie contents of Opuntia ficusindica was 378.21 kcal. The content of total dietary fiber was 36.54%. The essential and non-essential amino acids contents were 1,635.14 mg and 3,012.68 mg, respectively. Potassium was the most abundant mineral followed by Ca, Mg, and Na, showing that Opuntia ficus-indica is an alkali material. The electron-donating activity (EDA) of Opuntia ficus-indica was 29.85~44.57%, and the activity was dependent on the sample concentration. Total phenolic content of Opuntia ficus-indica was 2.21 ${\mu}g$/mg, and total flavonoids content was estimated as 1.80 ${\mu}g$/mg. Opuntia ficus-indica extract showed the highest reducing power (OD 700=3.18) at a concentration of 6.25 mg/mL. Based on the above results, we determined that the Opuntia ficus-indica has potential antioxidant activities.

This research studied the effects of Backryeoncho (Opuntia ficus-indica var. saboten) extract as an additive in kimchi in various amounts (0%, 0.4%, 0.8%, 1.2%), and its acceptance by middle school students in the Jeonju area. The treated kimchi had a higher pH than the untreated kimchi without extract, and the titratable acidity of the kimchi decreased with the addition of the Backryeoncho extract. The degree of salinity decreased in kimchi with the added Backryeoncho extract in a dose-dependent manner. The cutting force and compression force were higher in kimchi where the extract was added during the fermentation period resulting in improved texture of the kimchi. The addition of the extract slowed growth of total bacteria (1.83~2.12 log CFU/mL) and lactic acid bacteria (1.4 log CFU/mL) as compared with the control sample. In the sensory evaluation of overall taste, kimchi with 0.8% extract added demonstrated higher evaluation in overall categories. The acceptability of Backryeoncho extract as an additive in kimchi among middle school students was higher than in the control sample, with an optimum additive of 0.4% extract, based on the lowest volume of leftovers.

This study was aimed at evaluating a proper mixing ratio of making Beaknyuncho(Opuntia ficus-indica var. saboten) Sulgidduk with different types of extraction, a fruit and a stem of Beaknyuncho, and by different making methods. As a result, moisture content was the highest(43.22%) in FP1 and the lowest(38.55%) in SJ60. The low lightness and yellowness are increased with more powder and juice of both fruit and stem added. The mechanical characteristics, hardness, adhesiveness and gumminess were increased as powder and juice were added. And cohesiveness and springiness were decreased. The identification test showed that a sample containing stem juice was the most preferable for taste, chewiness, moistness and after-taste. The preference test showed that a sample containing stem juice was the most preferable for color, texture and overall quality and a sample containing stem powder was preferable for flavor and taste. Both SJ60 mixed with 60% Beaknyuncho stem juice and FP3 mixed with 3% fruit powder proved to be the most desirable in both sensory evaluation and texture characteristics.

In this study, we assessed antioxidant, anti-diabetic, and anti-Alzheimer activities of Opuntia ficus-indica var. saboten (OFI) at harvest time. OFIs were cultivated December 2015~November 2016 in Jeju island. The 70% ethanol extracts of OFI were used to investigate total polyphenol and flavonoid contents, antioxidant(DPPH and ABTS radical scavenging assay), anti-diabetic(yeast ${\alpha}$-glucosidase and rat ${\alpha}$-glucosidase inhibition assay), and anti-Alzheimer(Acetylcholinesterase and butyrylcholinesterase inhibition assay) activities. Total polyphenol and flavonoid contents of OFIs were $17.40{\sim}23.11{\mu}g$ garlic acid/mg Ex and 2.17~6.22 ug (+)-catechine/mg Ex, respectively. DPPH and ABTS radical scavenging activity of OFIs were 131.98~184.90 mg ascorbic acid(AA) eq/100 g and 63.60~101.83 mg AA eq/100 g, respectively. In the anti-diabetic and anti-Alzheimer activities, 70% ethanol extracts of OFI exhibited moderate inhibition activity, compared to control (acarbose and beberine). Total polyphenol and flavonoid contents, antioxidant, anti-diabetic, and anti-Alzheimer activities were no significant differences by season, respectively. Therefore, information on comparative biological evaluations of OFI may be a beneficial in exploring functional food and drug development.

This study was conducted to analyze the nutrient compositions of stem and fruit of Opuntia ficus-indica var. saboten (OF) and Opuntia humifusa (OH). The results of the two-way analysis of variance test indicated that the parts, varieties and parts*varieties had influence on nutrient content except crude protein, soluble dietary fiber, Fe, Se, I, vitamin E, niacin and vitamin C. Moisture and crude ash content was higher in stem than in fruit, while crude lipid and insoluble dietary content was higher in fruit than in stem. Mineral content revealed that K (1,313.67 mg% in OF, 1,351.38 mg% in OH) was the highest in fruit and Ca (5,146.29 mg% in OF, 1,388.19 mg% in OH) was the highest in stem. Vitamin C was the most abundant vitamin in the fruit of OF (199.98 mg%) and OH (187.12 mg%). Polyunsaturated fatty acid was the highest among fatty acids (66.9~70.1%), with higher content in the stem (753.89 mg%) than fruit (578.01 mg%) in OF, while higher in the fruit (1,093.63 mg%) than stem (475.07 mg%) in OH. Moisture, crude protein, Mg, Se and riboflavin was higher in OF than OH; whereas, crude lipid, insoluble dietary fiber, total dietary fiber and monounsaturated fatty acid were higher in OH than OF. These results indicated that OF and OH could be a good food source for Ca, K and Vitamin C. Also, different nutrient content by parts and varieties, can be helpful in choice of parts or varieties for consumer purposes.

Cactus (Opuntia ficus-indica var saboten Makino) is a tropical or subtropical plant, which is widely used as folk medicine for burned wound, edema and indigestion. We previously found that the ethanol extract of cactus stem showed anti-inflanunatory action. This investigation was designed to isolate the active fraction of anti-inflanimatory action from cactus stem by solvent extraction and colunm chromatography. Carrageenan-induced paw edema in rats and acetic acid-induced writhing test in mice were used as animal models to search anti-inflammatory and analgesic activities. respectively. The ethanol extract of cactus stem was consecutively extracted with hexane, ethyl acetate, and n-butanol. The hexane fraction was the most effective in carrageenan-induced paw edema, and then was separated in colunm chromatography of silica gel by the elution with hexane/ethyl acetate mixture. The most effective fraction 1 was separated in a second colunm chromatography by eluting with hexane/diethyl ether mixture. The most effective fraction 1-5 was obtained, and separated in a third column chromatography by eluting with hexane/chloroform mixture. It produced the most effective fraction 1-5-1. Moreover, fraction 1-5-1 showed an inhibitory effect on acetic acid-induced writhing in the doses of 30mg/kg and 60mg/kg,p.o.,indicating that it also contained analgesic activity.
