Polyamine constituents of fresh Panax ginseng root and dried white ginseng were extracted with 5% trichloroacetic acid, respectively. The isolation of polyamine constituents was conducted by the cation exchange chromatography using $Dowex-50W{\times}8$ resin and the detection was performed with TLC. Identification of the polyamine was carried out by the methods of IR, NMR, MS spectroscopy and GLC. Polyamine constituents of white and fresh ginseng root were identical and composed of five different polyamines. The major polyamine in white and fresh ginseng root was determined as putrescine.

Pathogen infections or mastitis inflammations usually develop differently on each udder of lactating cow. Although healthy udders will be attacked by the mastitis pathogens or the pathogens from blood in a long term, they would not be always inflamed. Somatic cell counts (SCC) in milk, which is utilized as an index of mastitis diagnosis, and the relation among SCC and milk constituents will have to be examined on each udder individually. Twelve cows of a Holstein cow herd in Nasu Research Station, which were suffering clinical or non-clinical mastitis, were selected, and SCC and milk constituents on each udder milk were measured. The effects of mastitis infection on udder milk components were relatively small except lactose content on udder milks of non-clinical mastitis (SCC< $10.0{\times}10^5$ per ml milk). On udder milks of clinical mastitis, however, high negative correlations were recognized between SCC and milk components. On different sampling days, high contents of fat and protein corresponded to that of total solids.

In order to detect constituents with similar actions to rutin in the genus Lespedeza plants growing in Korea, twelve species were collected in Chung Buk and Kyung Ki Provinces and subjected to systematic extraction. When the extract was examined for flavonoid by adding flavonoid reagents, all the species gave positive cofirmatory tests. The examination of the flavonoid consitituents by T.L.C. gave the following results: as rutin-like constituents, quercetin was detected in L. cyrtobotrya, L. maritima and L. bicolor var. melanantha and eriodictin-like constituents were detected in seven species. Of those twelve species, five species, L. cuneata, L. cyrtobotrya, L. maritima, L. bicolor var. melanantha and L. patentibicolor were found to contain kaempferol. All of them appear to contain lespedin and eriodictiol.

Volatile constituents obtained by water distillation from the aerial parts and root of Onosma dichroanthum Boiss (Boraginaceae) native to the north of Iran were investigated by GC and GC/MS for the first time. Palmitic acid (39.61%) and decane (31.39%) were the major components in the root while decane (26.26%) and phytol (25.52%) were the predominant constituents in the aerial parts. Ketones, aldehydes, alkanes, fatty acids, oxygenated diterpenes and sesquiterpenes were characterized as the most phytochemicals in the aerial parts. Alkanes and fatty acids were identified as the main groups in the root volatile substances. There were two ketone derivatives, belong to apocarotenoids, in the aerial parts; β-ionone and hexahydrofarnesyl acetone.

Wheat straw was treated with 4 per cent urea at a moisture level of 50 per cent alongwith different levels of boric acid viz. 1, 2, 3 and 4 per cent, under laboratory conditions to know the impact of boric acid on ammonia-N fixation in the straw. Murrah buffaloes were used for determining the disappearance of dry matter, CP and fibre constituents by nylon bag technique. Ammoniation increased CP content of wheat straw, which increased further due to addition of boric acid. Low level of boric acid (1%) had no adverse effect on fibre constituents disappearance but at higher levels there was a depressioon in the disappearance of fibre coonstituents. It can be concluded that low level of boric acid was sufficient to trap the excess ammonia released during urea ammoniation of wheat straw without affecting other constituents and their disappearance in the rumen of buffaloes.

Processing of medicinal plants is one of the processing methods for reducing of toxicity or improving of effect on medicinal plants. In this study, we studied the changes in the constituents and antioxidant activity in accordance with the processing conditions by the salt water of Citrus unshiu Markovich. Changes in antioxidant activity was measured by the DPPH method and changes in the components were analyzed by high performance liquid chromatography. As a result, the content of the main constituents (narirutin, hesperidin) and total polyphenol were increased by increasing the concentration of salt water. Moreover, antioxidant activity was increased gradually in proportion to the increase of the total polyphenol content.

The earthworm(Annelid) is a herbicine which has traditionally been used in the treatment of infectious fever, jaundice, infection of middle ear, laryngitis, pharyngitis, nephritis, headache, toothache and certain urinary tract infections from the olden times. Before the isolation and purification of biologically active components we analyzed the basic constituents(proteins, amino acids, mineral, etc.) with lyophilized powder of Lamnodrilus gotai Hatai. The results were as follows: Minerals detected and quantitatively analyzed were $Ca^#$, $Mg^#$, Fe, Zn, Mn, Cu, Co, Cr, Ni, Ge and Se. Amino acids detected were alanine, phenylalanine, leucine, glutamic acid, tyrosine, threonine, arginine, aspartic acid, methionine, lysine, serine, histidine, isoleucine, glycine, proline and etc. The constituents of proteins, fat, fiber, ash and phosphorous were measured. These constituents were compared and discussed with those of other investigations.

To search for the new development of industrial application of woody plants, the chemical composition of the volatile constituents from woody plants (Evodia daniellii, Clerodendron trichotomum, Prunus padus, and Zanthoxylum ailanthoides) was determined by GC and GC/MS spectrometric analysis with the aid of NBS, Wiley Library and RI indice searches. The major constituents were t-ocimene from the leaves of E. daniellii, linalool from the leaves of C. trichotomum, benzaldehyde from the leaves and twigs of P. padus, ${\beta}$-thujene from the leaves of Z. ailanthoides, and 2-undecanone from the stems of Z. ailanthoides. These results suggested that the major volatile constituents of woody plants could be a useful lead compound in the development of functional materials for industrial application.

Seven phenolic compounds (1-7) were isolated from the tubers of Gastrodia elata. Their structures were elucidated on the basis of MS and NMR spectral data. p-Ethoxymethyl phenyl-O-${\beta}$-D-glucoside (1) was proved to be a new compound, with N-(p-hydroxybenzyl)-adenosine (7) isolated from this plant for the first time. In this study, the protective effects of the six constituents (1-6) on PC12 cells against the cytotoxicity induced by KCI and glutamate were also investigated. The viability of the PC12 cells was significantly enhanced by pretreatment with the six phenolic constituents.
