Opuntia Ficus has been an epiphyte plant since it was introduced in Cheju island as an ornamental plant two hundred years ago. And now it is grown as many as it is designated to local souvenir No.35. The fruit of this plant contains red-purple sap, which is due to be used in coloring clothes. This study aims at confirmation of use possibility as eco-friendly dyeing stuffs on extract from opuntia ficus fruits and contributing to the practical use of natural dyeing. Thus this study was investigated the dyeability of extract from opuntia ficus fruits on the silk fabric. Antioxidants were used ascorbic acid, L-cysteine, prophyl gallete. After dyeing, K/S and dye fastness were measured. The results were as follows; Maximum absorption band of extract from opuntia ficus fruits was 534.5nm. The appropriate dyeing condition was bath ratio 50:1, dyeing temperature $30^{\circ}C$, dyeing concentration 50%, dyeing time 50min, pH 3,concentration of all antioxidants 3%. Addition of antioxidants brought increase of K/S value. And K/S value and dye fastness had the greatest value when ascorbic acid was added

From the stems and fruits of Opuntia ficus-indica var. saboten, eight flavonoids, kaempferol (1), quercetin (2), kaempferol 3-methyl ether (3), quercetin 3-methyl ether (4), narcissin (5), (+)-dihydrokaempferol (aromadendrin, 6), (+)-dihydroquercetin (taxifolin, 7), eriodictyol (8), and two terpenoids, (6S,9S)-3-oxo-$\alpha-ionol-\beta$-D-glucopyranoside (9) and corchoionoside C (10) were isolated and identified by means of chemical and spectroscopic. Among these isolates, compounds 3∼5 and 8∼10 were reported for the first time from the stems and fruits of O. ficusindica var. saboten.

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.
