From the legumes of Albizzia julibrissin Durazzini (Leguminosae), a mixture of long-chain alcohols, ${\alpha}-spinasterol$, a mixture of acylated sterol glycosides and ${\alpha}-spinasteryl$ $3-O-{\beta}-D-glucoside$ were isolated. Two mixtures of long-chain alcohols and acylated sterol glycosides were characterized as 1-hexacosanol (major) and 1-tetracosanol, and $3-O-[6'-O-palmitoyl-{\beta}-D-glucosyl]-{\alpha}-spinasterol$ (major) and its 6'-O-stearoyl ester. All compounds were identified on the basis of spectral data and chemical reactions.

Assay-guided fractionation of the methanol extract of the leaves of Albizzia julibrissin has furnished quercitrin (1) and afzelin (2) as the scavengers of DPPH radical. Quercitrin and afzelin showed scavenging activity of DPPH free radical with the $IC_{50}$ values of 17.3 and 71.5 ${\mu}M$, respectively.

Repeated column chromatography of an ethyl acetate extract of the root bark of Albizzia julibrissin Durazz afforded four compounds, euscaphic acid ester glucoside (1), luteolin-7 -O-neohesperidoside (2), (+)-medioresinol (3), (-)-syringaresinol (4). Their structures were determined by chemical and spectroscopic methods. Compounds 1-4 were isolated from this plant for the first time. Among these compounds, (+)-medioresinol (3) exhibited moderate cytotoxic activity against XF 498 and HCT 15 cell line.

From the EtOAc fraction of the MeOH extract of Albizzia julibrissin (Leguminosae）, a rare 5-deoxyflavone (geraldone, 1）, isookanin (2）, luteolin (3）, an isoflavone (daidzein, 4）, five prenylated flavonoids ［soph6f1avescenol (5）, kurarinone (6）, kurarinol (7）, kuraridin (8） and kuraridinol (9）］, a cerebroside (soya-cerebroside I, 10）, and $(-)-syringaresinol-4-O-{\beta}-D-glucopyranoside$ (11） were isolated and characterized on the basis of spectral data. Compounds 2, 3, and 11, showed 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity.

This study was performed to determine whether stem bark extract containing saponin of Albizzia julibrissin in the diet influences gonadal maturation and spawning in medaka (Oryzias latipes). The crude extraction containing saponin (HaBC) was partially purified from n-BuOH extraction of A. julibrissin stem bark by Diaion HP-20, Silica gel and Sephadex LH-20 chromatographies. We fed diets supplemented with HaBC to medaka. We then studied the effects of the HaBC supplement on the suppression of gonadal maturation and spawning in female medaka that were reared in aquaria with recirculation systems. In the experiment with immature female medaka, the periods of initiation of gonadal maturation and spawning were delayed in the fish that were fed diets supplemented with at least HaBC 20 mg/g-feed. In the experiment with mature female medaka, the fish that were fed diets supplemented with at least HaBC 20 mg/g-feed had lower GSIs than the control diet group did. The results showed that the growth of the immature medaka was not correlated with the amount of supplementation of HaBC in the diet. However, the condition factors (CF) in the medaka that were fed diets supplemented with at least HaBC 20 mg/g-feed were higher than in the medaka fed on the control diet. We concluded that extracts containing saponin from the stem bark of A. julibrissin have the potential to inhibit gonadal maturation in female medaka, but they did not act as growth stimulation. Further studies are required to determine the mechanism of the action.

In vitro culture system was established to induce multiple shoots of Albizzia julibrissin Duraz. by investigating the effects of cytokinins. Cotyledon, hypocotyl and root explants were cultured on MS media supplemented with either three different plant growth regulators or their combinations. The most effective cytokinin sources were zeatin 2.0 + TDZ 0.5 mg/L in cotyledon, zeatin 1.0 mg/L in hypocotyl, and BA 0.2 + TDZ 0.01 mg/L in root explant for producing shoots ($5.67\;{\pm}\;1.20$, $19.50\;{\pm}\;3.50$, and $20.50\;{\pm}\;2.47$, respectively). Also, zeatin treatment was tended to induce more shoots rather than the combinations of other cytokinins. In addition, the root induced in 1/2 MS medium without any plant growth regulators was longer and thicker than treatments of IBA, NAA, IAA and 2.4-D as auxins. Overall, the highest average percent of in vitro shoot formation was 73% from three different types of explants with treatment of zeatin (1.0mg/L).

Objectives: This study assessed the cytotoxicity of the metallic mordant cupric acetate (CA) and the protective effect of Albizzia julibrissin (AJ) leaf extract on CA-induced cytotoxicity in NIH3T3 fibroblasts. Methods: For this study, cell viability and antioxidative effects such as the inhibitory activity of lipid peroxidation (LP) and superoxide anion-radical (SAR) scavenging activity were assessed. Results: CA significantly decreased cell viability in a dose-dependent manner, and the $XTT_{50}$ value was measured as $55.0{\mu}M$ of CA. The cytotoxicity of CA was determined as highly toxic by Borenfreund and Puerner's toxic criteria. The catalase antioxidant significantly increased cell viability diminished by CA-induced cytotoxicity in these cultures. Regarding the protective effect of AJ leaf extract on CA-induced cytotoxicity, AJ leaf extract remarkably increased the SAR scavenging ability and the inhibitory ability of LP. From these findings, it is suggested that oxidative stress is involved in the cytotoxicity of CA, and AJ leaf extract effectively protected CA-induced cytotoxicity via antioxidative effects. Conclusions: Natural resources like AJ leaf extract may be a putative therapeutic agent for treatment or alleviation of the toxicity induced by CA metallic mordant.

Germination respone to sulfuric acid treatment, temperature, light and underwater condition were experimented for Albizzia julibrissin Durazz. seed. It took 60 minutes to break the dormancy of impermeable seed for the effective sulfuric acid treatment, and temperature sensitivity was decreased by 90 minutes' treatment. The germination rate of the seed was highest, i.e. 96% at 60 minutes acid treatment in a 21。C growth chamber. On the occasion of light sensitivity, the seed was light indifferent. The imbibition rate of seed was higher at 27。C than 21。C and in proportion to the period of acid treatment time. A. julibrissin Durazz. seed were well germinated at underwagter condition.
