The objective of this study was to examine the impact of three categories of supplements on intake and diet induced difference on degradation of straw substrates. Sixteen crossbred cattle fitted with rumen cannula were randomly divided into 4 equal groups. Animals were fed on wheat straw ad libitum without any supplement except mineral mixture (control; $T_1$) or supplemented with concentrate mixture (CS; $T_2$) or green Lucerne (GLS; $T_3$) or urea-molasses block lick (ULS; $T_4$). Total dry matter intake in $T_2$, $T_3$ and $T_4$ was increased by 70, 54 and 49%, respectively compared to $T_1$ which was only 1.55 kg/100 kg B.Wt. Other than control animals, straw intake was less on $T_3$ than $T_2$ or $T_4$. In Sacco degradation of untreated and urea treated wheat or paddy straw in different treatments indicated that the supplements had a significant (p<0.01) impact on rapidly soluble (A) and insoluble but potentially degradable (B) fractions of straw. Urea treatment increased fraction-A but, provision of supplement improved fraction-B also. Effective degradation (ED) of OM was better on $T_2$. Rate of degradation (C) of OM and CWC was dependent on diet and type of straw but hemicellulose and cellulose were related to latter factor only. ED of cell wall carbohydrates (CWC) was similar in $T_2$ and $T_4$ but higher than $T_3$. CS was more effective in improving the degradation of both untreated and urea treated straw while ULS was effective on the former only. CS had more impact on superior quality straw while contrary was true with ULS. Although GLS improved intake and degradability of untreated and urea treated straws, its bulkiness affected the straw intake compared to other supplements.

Chemical composition and contents of carbohydrates, lignin, and extractives in Moso(Phyllostachys pubescens Mazel), Henon(Phyllostachys nigra var. henonis Stapf ex. Rendle), and Timber bamboo(Phyllostachys bambusoides Sieb. et Zucc.) known as economically valuable bamboo species in Korea were analyzed as a function of ages. All of tested bamboo species were composed of fucose, arabinose, rhamnose, galactose, glucose, xylose, and mannose. Glucose was the sugar which showed the highest content followed by xylose. The contents of others were below 3%. Sugar contents of bamboo shoots showed the lowest among the tested bamboo samples, and the constant rates were shown after 50 days of growth. Lignin content increased by the growth of one year, and the increasing rates tended to be constant after the growth of three years. Bamboo shoots have the highest contents of acid-soluble lignin, which turned into insoluble lignin after the growth of 50 days. Bamboo shoots showed the highest content of extractives and tend to be decreased by the growth of 50 days and then the content increased slowly in proportion to the period of bamboo growth. No relationship was found between species and chemical composition of bamboo. However, there were significant difference in chemical composition between bamboo shoots and 50-day old bamboo.
Organic by-products derived from cellulose and lignin during organosolv pretreatments of yellow poplar wood (Liriodendron tulipifera) in the presence of $H_2SO_4$ and NaOH as catalysts, respectively, were subjected to various analyses to elucidate their effects on further performance of biological ethanol fermentation and provide preliminary data for the structure and utilization of organosolv lignin. Monomeric sugars amounted to ca. 2.2-7.7% in the organosoluble fraction of the organosolv pretreatment with $H_2SO_4$, while significantly low amount of sugars (0.2-0.3%) were determined in that of the organosolv pretreatment with NaOH. In case of addition of $H_2SO_4$ during organosolv pretreatment of biomass, a fermentation of the organosoluble fraction could be considered as an essential process to increase an efficiency of biomass utilization as well as yield of bioethanol. Precipitates, insoluble by-products in the solvent mixture, were also cficiency oed by diverse analytical methods and revealed that these were typically composed of a lignin moiety regardless of catalyst. According to the results of nuclear magnetic resonance (NMR), Fourier Tcinsform Infrared Spectroscopy (FT-IR) and Gel permeation chromatograp r (GPC), the main components of precipitates seem to be lignin polymers. However, their structures could be slightly modified during pretreatment and mixed with some carbohydrates by chemical bonds and/or physical associations.

To investigate C and N metabolisms in response to potassium-deficient stress during regrowth of Italian ryegrass(Lolium multiflorum L.), C and N metabolites were analyzed at day 0 (cutting date), 6, 12 and 24 days after defoliation. K-sufficient (control, +K) and K-absent (-K) nutrition solutions were applied from 7 days before defoliation, and continued for one cycle of 24 days-regrowth period. During 24 days of regrowth dry matter of regrowing shoots and remaining tissues were not significantly different between +K and -K treatment. In remaining stubble, all C compounds in both +K and -K treatment largely decreased (69% to 84% of the initial level) during the first 6 days of regrowth, and then rapidly recovered. The decline of soluble sugars and fructan in roots for the first 6 days much less in the -K medium. Amino acids, soluble and insoluble proteins in stubble also feel down during the first 6 days, thereafter actively replenished in both +K and -K treatment. The decline of nitrate in stubble prolonged to 12 days of regrowth. Initial amounts of all N compounds in roots were significantly lower in the -K medium. Higher accumulation of amino acids and soluble protein in roots in the -K medium was observed after 12 days of regrowth. In regrowing shoots, 3 all carbohydrates increased with a very similar pattern for both treatments. Nitrate was not significantly different between two treatments. Depress of soluble protein accumulation in -K medium was noteworthy after 12 days of regrowth. These results indicated that an active utilization of organic reserves occurred to support regrowth even under K deficient condition with a similar extent with K sufficient condition.

However the crude ash content of new vegetables was 7 times higher than that of grain. Total dietary fiber was ranged from 32.61% (Costamary) to 41,22% (Treviso) as dry matter basis. Insoluble dietary fiber was ranged from 21.58% (Red leaf beet) to 28.95% (Treviso) as dry matter basis. Soluble dietary fiber was ranged from 6.60% (Nakai) to 14.70% (Common danelion) as dry matter basis. Total carbohydrates was ranged from 73.62% (Salad bowl) to 36.30% (Red leaf beet) as dry matter basis. Neutral detergent fiber was ranged from 48.83% (Nakai) to 29.60% (Red leaf beet) as dry matter basis. Acid detergent lignin was ranged from 27.65% (Salad bowl) to 2.92% (Corn salad) as dry matter basis. Hemicellulose was ranged from 22.55% (Nakai) to 2.15% (Salad bowl).
Green tea, a leaf of the plant Camellia sinensis, is one of the most consumed traditional oriental beverages. Green tea has been considered a medicine and a healthful beverage since ancient times, but recently it has received a great deal of attention because of its antioxidants like polyphenols. Moreover, green tea contains amino acids, carbohydrates, proteins, chlorophyll, volatile compounds, minerals, and phytochemical components that are essential or helpful to human health. Depending on the manufacturing process, green teas are classified into several types. Among these, powdered green tea can be effective in the absorption of ingredients compare with other types of green tea since we take the beverage with powder itself. In this paper, the contents of general ingredients (moisture, proteins, fat, carbohydrates, and ash), minerals (Fe, Mg, Ca, Na, K, and P), hunter color values, and alcohol insoluble substance were determined in total of six powdered green teas commercialized in Korea and Japan.

Total dietary fiber was 25.35% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 1.80 % and 23.56 %, respectively. The protein were contained total 18 different kinds of amino acids. The contents of non-essential and essential amino acids were 4,898.78mg and 5,953.51mg. The K was the largest mineral followed by Ca, P and Mg, which means Flos Sophora japonica Linne is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 29.69%, 34.93% and 35.38%. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of vitamin C in Flos Sophora japonica Linne was higher than that of any other plant, which suggest that it could increase blood elasticity. The content of rutin, which is responsible for capillary vessel permeability, was 22.60%. The contents of water soluble antioxidative materials in 1 mL of water-extracted Flos Sophora japonica Linne were 3.9 ${\mu}$g which is comparable to 1233.0 mmol of vitamin C in antioxidant effect. The general nutrients and other antioxidatant bioactive materials in Flos Sophora japonica Linne were also potential materials for good health food. It is expected that follow up study of Flos Sophora japonica Linne through developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.

Background: The Unani system of medicine has been practised since centuries for the treatment of a range of diseases. In spite of their efficacy they have been widely criticised due to the lack of standardization and poor quality control. Standardization of Unani medicine is a valuable issue at the present because they are very prone to contamination, deterioration, adulteration and variation in composition due to biodiversity as well as careless collection. Objective: To Standardize and Development of HPTLC Fingerprinting of a polyherbal Unani formulation Qurs-e-Safa. Materials and methods: The conventional and modern analytical techniques were used to standardise Qurs-e-Safa. The study was carried into three different batches of Qurs-e-Safa prepared with its ingredients. The parameters studied are organoleptic, microscopic, physicochemical parameters, phytochemical screening, TLC, HPTLC profile, aflatoxin, microbial load and heavy metal analysis. Results and conclusion: Qurṣ-e-Sa'fa is dark yellow in colour and aromatic smell. Uniformity of diameter and weight variation were found to be 13 ± 0, and 524.7 ± 1.72 mg. friability, hardness and disintegration time of all 3 batches were found to be (0.0615 ± 0.004, 0.0885 ± 0.0047 and 0.0725 ± 0.0058), (3.5 ± 0.2886, 3.67 ± 0.1674 and 3.67 ± 0.1674) and (16 to 17 minutes). Extractive value were found to be maximum in distilled water (38.488 ± 0.20, 37.3824 ± 0.38 and 39.8177 ± 0.13) followed by alcohol (27.5406 ± 0.54, 27.5656 ± 0.32 and 26.9229 ± 0.25). Loss of weight on drying, pH, total ash, acid insoluble ash, qualitative test was set in. Phytochemical screening revealed the presence of Carbohydrates, Phenols, Resins, Proteins, Steroids, fixed oil and Flavonoids. The microbial load was found absent and heavy metals were within permissible limits. The data evolved from the study may serve as a reference to validate and also help in the quality control of other finished products in future research.
