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.

In order to develop a natural food preservative, the root bark of Morus alba was extracted with several solvents, and then antimicrobial activity was investigated. The optimum extracting condition for the antimicrobial substance from the sample, minimum inhibitory concentration (MIC) of the extracted substance against microorganisms were also examined. The antimicrobial activity of the ethanol extract form the sample was stronger than those of the extracts by the other solvents such as water, methanol. ethyl acetate and acetone. The optimum extracting condition for antimicrobial substance from the sample was shaking extraction twice for 5 hours at room temperature in case of 7 times of absolute ethanol added to the crushed root bark of Morus alba. The ethanol extract from the root bark of Morus alba had strong B. cereus, L. monocytogenes and S. aureus. Especially, Bacillus species was the most susceptible to the extracted substance. The ethanol extract showed antimicrobial activity against Gram negative bacteria(MIC, 160~1600 ug/ml) and yeasts(MIC, 1600 ug/ml) such as C. albicans and S. acidifaeciens. The extract also showed growth inhibition against molds such as A. niger, A. parasiticus, A versicolar and T. viride.

The ethanol extract from the root bark of Morus alba showed the strongest antimicrobial activity on the growth of almost all the tested microorganisms which were food-borne pathogens and food-related microorganisms. 1) In order to isolate and purify of antimicrobial substance extracted from the root bark of Morus alba, the antimicrobial substance from the ethanol extract which exhibited a strong antimicrobial activity was purified by solvent fractionation, silica gel column chromatography, TLC and HPLC. Among the fractions fractionated by 4 kind of solvents from the ethanol extract, the antimicrobial activity of ethyl acetate fraction had the strongest antimicrobial activity against B. subtilis. Unknown compound were isolated from the ethyl acetate fraction by silica gel column chromatography, TLC and HPLC and the compounds showed strong absorbance at 207, 217 and 285 nm, therefore, it was supposed to be a kinds of aromatic compound.

The ethanol extract from the root bark of Morus alba showed the strongest antimicrobial activity on the growth of almost all the tested microorganisms which were food-borne pathogens and food-related microorganisms. Therefore, fatty acid composition, amino acid composition and shape change of microorganisms treated with the ethanol extract from the root bark of Morus alba were examined. In effects of treatment with the ethanol extract on the fatty acid compositions of B. subtilis, S. aureus and E. coli, fatty aicd compositions such as hexadecanoic acid (16:0) and octadecanoic acid (18:2) of the tested strains were increased but pentadecanoic acid (15:0) heptadecanoic acid (17:0) and acid (16:1) and octadecenoic acid (18:1) of E. coli were decreased. The ethanol extract did not significantly affect the aminn acid composition of the tested strains. Transmission electron micrographs of microorgani는 treated with the ethanol extract exhibited morphological changes that irregularly contracted cell surface in S. aureus and destructed cell walls in B. subtilis and E. coli.

In this study, we examined antioxidative effects and the anti-adipogenesis effect of different parts of Cudrania tricuspidata (C), and Morus alba (M). Total polyphenol contents were highest in M-root ($34.56{\pm}0.045mg\;GAE/g$), and there was no significant difference, between C-root and M-leaf. Total flavonoid contents of C-root were highest ($23.07{\pm}0.004mg\;QE/g$). To examine antioxidant activities of C and M extracts, DPPH and ABTS radical scavenging activity, and FRAP assay, was used. Results show that antioxidant activities of C and M extracts increased, in a dose-dependent manner. Adipocytes are generated by preadipocyte differentiation, during adipogenesis. Matured adipocytes accumulate in abnormal and cause obesity. We investigated effects of leaf and root extracts of C and M, on lipid accumulation, in 3T3-L1 adipocytes. Changes in cell morphology, and degrees of lipid accumulation in adipocytes, were evaluated by Oil Red O staining. Root extracts of C and M, reduced lipid content in a dose-dependent manner. Therefore, root extracts of C and M, may be good candidates for managing obesity.

The mulberry (Morus alba L.) root barks were extracted with 80% aqueous methanol at room temperature. The concentrated extract was partitioned as ethyl acetate (EtOAc), n-BuOH, and $H_2O$ fractions. From the EtOAc fraction, five triterpenoids were isolated through the repeated silica gel and octadecyl $SiO_2$ column chromatographies. According to the results of physico-chemical and spectroscopic data including nuclear magnetic resonance, mass spectrometry, and infrared, the chemical structures of the triterpenoids were respectively determined as ${\alpha}$-amyrin (1), ${\alpha}$-acetyl amyrin (2), lupeol (3), betulinic acid (4), and glutinol (5). Compounds 1, 3, and 5 were isolated for the first time from the mulberry root bark.

The root barks of Morus alba L. were extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH, and $H_2O$ fractions. The repeated silica gel, octadecyl silica gel, and Sephadex LH-20 column chromatographies of the EtOAc and n-BuOH fractions led to isolation of four phenolic compounds. The chemical structures of the compounds were determined as norartocarpanone (1), 2',4',7-trihydroxy-(2S)-flavanone (2), methyl ${\beta}$-resorcylate (3), and (Z)-oxyresveratrol-4-O-${\beta}$-$\small{D}$-glucopyranoside (4). Compound 4 was isolated for the first time from the root barks of M. alba L.

The methanolic extract of the root-bark of Morus alba L.(Mulberry tree) has the potent antibacterial activity against Streptococcus mutans. Its active component was identified to be sanggenon C. The active component had stronger anti-bacterial activity than berberine, having minimum inhibitory concentration(MIC) of $25\;{\mu}g/ml$. Moreover, the inhibitory effect of this component on the cellular adherence of Streptococcus mutans to glass surfaces also was more remarkable than that of berberine in the presence of glucosyltransferase(GTase) and sucrose in vitro. These results indicate that sanggenon C may play an important role in inhibiting plaque formation and caries incidence.

Mulberry extracts can be incorporated into skin-whitening products. The compound attributed to lighten the skin is arbutin, a form of hydroquinone that inhibits melanin release by suppressing the tyrosinase enzyme. For the cosmetic applications, the physiological effects of mulberry (Morus alba) extracts were investigated. The water soluble fraction of mulberry contains higher amount of protein (16.28~4.47%) in contrast to fat (1.55~1.41%). In addition, the fraction abundantly contains succinic acid (972.4-275.8 mg/g) and phosphoric acid (1,628.4-121.9 mg/g) in different parts of mulberry. The free radical scavenging ability in water soluble fraction was found to display remarkable effects in comparison with methanol and ethyl acetate fraction. The ethyl acetate-soluble of root and leaf showed remarkable tyrosinase inhibition activity by IC 50 (${\mu}g/ml$). The anticancer activity of methanol fraction obtained from mulberry using human cancer cell lines showed growth inhibition effect (270.14 mg/ml in Calu-6 cells, 295.29 mg/ml in HCT-116, and 332.29 mg/ml in MCF-7 cells, respectively). Based on the results, Morus alba extracts include cosmetic ingredients with antioxidizing and whitening properties.
