The main colorant of Morus alba L. fruit is anthocyanin which is a kind of flavonoid group. In this article, the dyeing properties of colorant extracted from Morus alba L. fruit were investigated on some silk fabrics. The results were as follows: The maximum absorbance of Morus alba L. fruit showed at 284 nm, and 516 nm by UV-VIS spectrophotometer. The dye adsorption increased according as dye concentration. The optimal dyeing temperature was $60^{\circ}C$ and the dye equilibrium was reached 40 minutes after dyeing. The highest K/S value of the colorant obtained at bath ratio 40:1. The effect of pH of dye solution showed higher K/S value at acidic than alkaline condition. Almost Mordants except pre-Fe and Sn did not significantly increased dye adsorption. The pre mordanted silk fabrics showed RP, P, and post mordanted ones showed PB, GY. The color fastnesses to light, washing, and perspiration were modified at pre-Sn mordanted samples.

Morus alba fruit contains several anthocyanins and flavonoids like cyanidin-3-O-rutinoside and quercetin-3-O-rutinoside. Extractions from Morus alba fruit were performed with five different compositions of ethanol/water [v/v]. High-Performance Liquid Chromatography (HPLC) was used for the validation and content determination of cyanidin-3-O-rutinoside and quercetin-3-O-rutinoside. The contents of cyanidin-3-O-rutinoside in ethanol extracts (100%, 70%, 40%, 20% and 0%, ethanol/water [v/v]) were 1.150%, 0.822%, 0.749%, 0.663% and 0.597%, respectively. Quercetin-3-O-rutinoside contents of ethanol extracts (100%, 70%, 40%, 20% and 0%, ethanol/water [v/v]) were 0.167%, 0.161%, 0.159%, 0.155% and 0.096%, respectively. The highest contents of cyanidin-3-O-rutinoside and quercetin-3-O-rutinoside were in the ethanol extract with 100% ethanol/water [v/v]. These HPLC analysis method could be used as basic data for standardization of functional food from Morus alba fruit.

Morus alba has been well known for its tonic effect or preventing of hypertension, aging, or diabetes mellitus in Asian countries. To evaluate the its effect on hair growth promotion, we performed the hair regrowth experiment with leaf, branch, root and fruit extract of Morus alba on animal model of C57BL/6 mouse. The hair regrowth effect was remarkable in the mouse treated branch and root extract (with what %), however, little effect on hair regrowth appeared on the mouse treated with leaf extract. Morus alba extract displayed antibacterial effects on Bacillus subtilis, Staphylococcus aureus, Pseudomonas and Candida albicans. These results indicated that branch and root extract of Morus alba could be applicable for hair regrowth or prevention of hair loss in human.

We examined the inhibitory activities against monoamine oxidase (MAO) of Morus alba in vitro and in vivo methods. Methanolic extract of M. alba showed significantly inhibitory activities on MAO-A and MAO-B that were prepared from rat brain and liver in vitro. The inhibitory activities were measured by serotonin and benzylamine as substrates, respectively. MAO-A and MAO-B activities were potently inhibited by ethylacetate extracts of M. alba in vitro tests. Those activities in vivo tests have different tendency each other. MAO-A activity was increased by the oral administration of methanolic extract of M. Alba, while, MAO-B activity was decreased. Consequently, we can suggest that M. alba may have the effects on the inhibitory activities against MAO both in vitro and in vivo.

Physicochemical characteristics and analysis of functional constituents of mulberry (Morus alba L.) fruit juices were investigated according to four different mulberry cultivars, including iksuppong, daeseongppong, cheongilppong and kwasangppong. Among the four mulberry cultivars examined, the small-sized cheongilppong had higher soluble solid content and lower titratable acidity, whereas the big-sized daeseongppong had higher titratable acidity and lower soluble solid content than other mulberry cultivars. Cheongilppong had higher contents of fructose and glucose, while daeseongppong had higher contents of citric and malic acids than the other mulberry cultivars. Kwasangppong had higher contents of two anthocyanins, cyanidin 3-glucoside and cyanidin 3-rutinoside, while cheongilppong had lower contents of two anthocyanins than the other mulberry cultivars. Daeseongppong had higher contents of resveratrols, flavonoids and moracin, whereas cheongilppong had higher levels of protocatechuic, chlorogenic and caffeic acids than the other mulberry fruits. Of the four mulberry cultivars, daeseongppong and cheongilppong had higher contents of GABA and DNJ, respectively, than the other mulberry cultivars. These results provide useful information to food technologists for the development and standardization of high quality mulberry juices as well as their processed foods.

The fruits of Morus alba L. were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol, and water fractions. The repeated silica gel ($SiO_2$) and octadecyl silica gel column chromatographies for the EtOAc and n-butyl alcohol fractions led to isolation of two phenolic compounds. The chemical structures of the compounds were determined as Diels-Alder type adducts, mulberrofuran E (1) and chalcomoracin (2) based on spectroscopic data analyses including nuclear magnetic resonance, mass spectrometry, and infrared spectrometry. Compounds 1 and 2 were isolated for the first time from the fruits of M. alba L. in this study.

We bred a mulberry cultivar named Suhyang through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test was carried out at four places (Suwon, Kongju, Wanju and Jinju) for six years from 2007 to 2012. This is belonging to (Morus alba L.) crossed between Josaenghongpisang (Morus alba L.) and Kaeryang (Morus alba L.) among mulberry genetic resources preserved in Suwon. Suhyang was high yielding cultivar in fruit productivity by 12% compared to control cultivar 'Chungil (Morus alba L.)' for four years. Although Suhyang was higher in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

Effects of Morus alba fruit extracts on monoamine oxidase (MAO) activity were examined in rats during and after physical exercise. Oral administration of M. alba extract (0.3 g/kg body weight) significantly increased brain MAO-A activity but decreased liver MAO-B activity when they were measured using serotonin and benzylamine as substrates. Type of physical exercises had significant effect on MAO activity. Brain MAO-A activity markedly decreased with physical activity-related stress compared to normal group, whereas Liver MAO-B activity increased up to 60 min after exercise. Lactate dehydrogenase (LDH) activity and lactate concentration in blood, clinical indices of physical exercise activities, were also determined for correlation to MAO activities. MAO-A activity of rats subjected to oral administration of M. alba extract and physical exercise increased whereas MAO-B and LDH activities, and lactate level decreased, All indices eventually recovered normal levels, These results suggest M. alba may increase capability of physical activities by modulating MAO activities during exercise.

We bred a mulberry cultivar named Sangmaru, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at three places (Suwon, Cheongju, and Jangseong) for seven years from 2008. This is tetraploidy variety belonging to Morus alba L. made by colchicine treatment on growing point of 'Chungil (Morus alba L.)' winter buds. Sangmaru was high yielding cultivar in fruit productivity by 6% compared to control cultivar 'Chungil (Morus alba L.)' for five years. Although Sangmaru was similar in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

The morphological and chemical characteristics of leaves and fruits were observed in the three mulberry varieties, including Daeryugppong(Morus Lhou(Ser.) koidz), Kugsang 20(Morus Lhou(Ser.) koidz) and Cataneo(Morus alba L.). The leaf development in spring was earliest in Cataneo and latest in Kugsang. Content of total nitrogen and Mg in leaf was the highest in Cataneo while that of P2O5, K and Ca in Daeryukppong. Flowers started to bloom from May 8 and in full bloom around May 15. Mature fruits began to set from June 10 to 15 and lasted by July 10 in Cataneo. Average fruit weight was heaviest in Kugsang 20(3.52 g/fruit), while lowest in Daeryukppong(1.61 g/fruit). In fruits, glucose and fructose were the major sugars. Citric acid was the most abundant organic acid in three varieties with its average content from 0.8 to 0.14%. The major pigment in fruit was anthocyanin and its content varied among varieties. The stability of anthocyanin was evaluated under various pH, temperature, and sugar concentrations. Rutin was the major flavonol glycoside present in fruits and its content varied from 0.92 to 3.36 mg/gDW. Other flavonol glycosides such as isoquercitrin and quercitrin were also detected in fruit.
