Mulberry leaves Julpyun(a traditional Korean rice cake) was prepared by adding Mulberry leaves powder in the ratio of 0%, 3%, 6% and 9% of rice flour, and tested for inorganic nature, physical function, chromaticity, and rheological properties. As the ratio of mulberry leaves powder increased, both the amounts of major inorganic ingredients, calcium, magnesium, and sodium, and the amounts of minor inorganic ingredients, iron, copper, and zinc, were increased proportionally. Thus, one way to increase the amounts of inorganic ingredients appeared to add mulberry leaves powder. In physical function test, control cake(0% mulberry leaves) showed the highest value in appearance and the value decreased as the amounts of mulberry leaves increased. In color, 3%-mulberry leaves-Julpyun gave the highest value followed by 0%, 6%, and 9%-Julpyun in order. The values of texture and moisture were decreased as the ratio of mulberry leaves powder increased. In rheometer test, 9%-mulberry leaves Julpyun showed the high values in hardness, cohesiveness, and brittleness. Therefore, as the amounts of mulberry leaves powder increased, the amounts of inorganic ingredients increased, but the value of physical function test decreased. 9% mulberry leaves Julpyun has the highest value of rheometer test.

This study was carried out to investigate solid-state fermentation method using cellulolytic lactic acid bacteria Lactobacillus plantarum TO-2100 in order to increase piperidine alkaloid contents in mulberry leaves. Piperidine alkaloid, one type of which include 1-deoxynojirimycin (1-DNJ), is known to inhibit ${\alpha}$-glycosidase activities. Using this strain, the optimal solid-state fermentation conditions on mulberry leaves powder were found as the following: initial moisture content, temperature and relative humidity were 20%, $30{\sim}35^{\circ}C$ and 60 ~ 70%, respectively, and the fermentation time was 72 hrs. The piperidine alkaloid contents in the fermented mulberry leaves were 2.86% on dry powder, which is 7-fold increase from that of non-fermented mulberry leaves. The 1-deoxynojirimycin contents after applying preparative thin layer chromatography were 2.02% on dry powder, which is 8 times higher than that of non-fermented mulberry leaves. ${\alpha}$-Glycosidase activities was inhibited by 65.7 ~ 84.7% with 3 ~ 5% treatments of hot-water extracts of the fermented mulberry leaves, compared to 16.2 ~ 40.2% with 3 ~ 5% treatments of hot-water extracts of non-fermented mulberry leaves. Therefore, the results suggest that solid-state fermentation method does indeed increase of piperidine alkaloid contents on mulberry leaves.

This study was conducted to investigate the effect of mulberry leaves on lipid metabolism in cho lesterol induced hypercholesterolemia rats. The mulberry treatment group showed decreases of serum lipid concentration compared with hyperlipidemic group. Also, Mulberry leaves inhibited the activity of HMG Co A reductase, increased lipase activity. In histopathological examination, abdominal aorta showed no critical lesions with mulberry leaves treatment. These results suggest that hypolipidemic effects of mulberry leaves on rats were the inhibition of cholesterol synthesis and acceleration of cholesterol catabolism in the liver. For human, serum triglyceride contents were more significantly decreased with treatment of mulberry leaves powder.

The in vivo digestibility of mulberry leaves (Morus alba) and the effects of the partial replacement of cotton seed with fresh mulberry leaf in rations on the performance of growing Vietnamese cattle was investigated. For the in vivo digestibility trial, twenty castrated rams of Phanrang breed (a local prolific breed) with an initial weight of 23-25 kg, were first assigned to four groups according to weight and then randomly assigned to one of four dietary treatments to determine digestibility of nutrients in mulberry leaves (M. alba), natural Bermuda grass (Cynodon dactylon), elephant grass (Pennisetum purpureum) and buffalo grass (Panicum maximum cv. TD 58). All forages were cut and chopped daily before being offered (at 120% maintenance) to the sheep. In the feeding trial, 20 Laisind (Vietnam yellow cows${\times}$Red Sindhy bulls) crossbred bulls averaged 18 month old and 184 kg were used to investigate the effect of partial replacement of cottonseed in the diet by mulberry leaves on live weight gain and feed conversion rate. The experiment was a randomized complete block design with four levels of fresh mulberry leaves which varied from 0 to 15% of total dietary dry mater and five animals per treatment over an 84 day period. The in vivo digestion trial showed the superior quality of mulberry leaves compared with the grasses. Chemical analysis indicated that mulberry leaves had the highest CP and the lowest NDF contents (22.3 and 31.1% DM, respectively) among the four forages tested. Digestibility of DM and OM of the mulberry leaf (66.4 and 71.8%, respectively) was also the highest but that of CP (58.2%) and NDF (58.4%) was the lowest of the four forages evaluated (p<0.05). Consequently, the ME value and therefore net energy (NE) and unit feed for lactation (UFL) values of the mulberry leaves, which was estimated from chemical composition and digestibility values, were the highest among the forages investigated in the present study. Results of the feeding trial showed no treatment effect on average daily gain (ADG) of the cattle. The values were 554, 583, 565 and 568 g/d for animals in the diets of 0, 5, 10, and 15% mulberry leaves inclusion, respectively. Total DM intake of the animal was not affected by the treatment when expressed as kg/animal/d. However, when adjusted for metabolic weight of the animal the DM intake was reduced (p<0.05) as whole cottonseed was replaced by mulberry leaves in the ration. When the level of mulberry leaves in the ration increased from 5 to 15% of dietary DM at the expense of whole cottonseed, CP and ME intakes of the cattle were significantly decreased (p<0.05) and the feed to gain ratio reduced by 8 to 14% as compared with the control diet (p<0.05). Mulberry leaf is a good feed ingredient for ruminants because of its high level of crude protein and high digestibility of nutrients and energy. Mulberry leaves can be efficiently used as a source of protein supplement to replace cottonseed, a more expensive animal feeds ingredient, in the diet for Vietnamese cattle.
