A number of sedative alkaloids were isolated from Sanjoin(酸棗仁), the seeds of Zizyphus vulgaris Lamark var. spinosus Bunge (Rhamnaceae) which is an important Chinese medicinal material used to treat insomnia and sometimes to treat sleepiness. Those compounds were designated as Sanjoinine-A, B, C, D, etc. depending on the order of increasing polarity. Sanjoinine-A, $C_{31}H_{42}N_4O_4$, $mp\;249^{\circ}$, $[{\alpha}]^{27}_D-316$, Sanjoinine-B, $C_{30}H_{40}N_4O_4$, $mp\;212{\sim}4^{\circ}$, Sanjoinene, $C_{29}H_{35}N_3O_4$, $mp\;281{\sim}2^{\circ}$, $[{\alpha}]^{22}_D-272$, Sanjoinine-D, $C_{32}H_{46}N_4O_5$, $mp\;256{\sim}8^{\circ}$, $[{\alpha}]^{22}_D-53.6$, Sanjoinine-F, $C_{31}H_{42}N_4O_5$, $mp\;228{\sim}9^{\circ}$, $[{\alpha}]^{22}_D-215$, and $Sanjoinine-G_1,\;C_{31}H_{44}N_4O_5,\;mp\;236{\sim}8^{\circ},\;[{\alpha}]^{22}_D-68.6$, were found as 14-membered cyclic peptide alkaloids, $Sanjoinine-G_2,\;C_{30}H_{42}N_4O_4,\;mp\;182^{\circ},\;[{\alpha}]^{22}_D-79.2$, as being open chain peptide alkaloid, and Sanjoinine-E, $C_{19}H_{21}NO_2$, $mp\;166^{\circ}$, $[{\alpha}]^{20}_D-146.2$, N-Methylasimilobine, $C_{18}H_{19}NO_2$, $mp\;193{\sim}5^{\circ}$, $[{\alpha}]^{20}_D-204$, Sanjoinine-Ia, $C_{18}H_{19}NO_2$, $mp\;155{\sim}7^{\circ}$, $[{\alpha}]^{20}_D-140$, Sanjoinine-Ib, $C_{19}H_{21}NO_4$, $mp\;184^{\circ}$, Sanjoinine-K, $C_{16}H_{19}NO_3$, $mp\;159{\sim}61^{\circ}$, $[{\alpha}]^{20}_D+35$, Caaverine, $C_{17}H_{17}NO_2$, $mp\;204^{\circ}$, $[{\alpha}]^{20}_D-80$, and Zizyphusine, $C_{20}H_{24}NO_4$, $mp\;214{\sim}6^{\circ}$, $[{\alpha}]^{20}_D+317$ as being aporphine alkaloids. The heat treatment of the cyclic peptide alkaloids produced their isomeric products which showed enhanced sedative activity. The chemical structure of the isomeric products will be discussed.

An analysis of changes in herbal tea composition according to the difference in processing conditions showed slightly reduced crude protein content and increased, moisture, crude fat and solid elution rate after treatment using the ash puffing process compared to roasting. Benzopyrene content was significantly reduced to 0.18 ppb from 0.51 ppb. This result indicated that, the $B({\alpha})P$ content differed depending on the processing condition and raw materials. Generation of food $B({\alpha})P$ is mainly include the thermal decomposition of food cooking, when the processing which is a main component of food carbohydrate, protein, fat reason despite severe heat treatment as a whole is to be detected even though the $B({\alpha})P$ in this way is considered to be. The taste, aroma and color did not show a large difference, but the strong bitters taste decreased.

Objectives : In this study we investigated the antiobese effects of mixed pills of pickled black soybeans with herbs(herbal Chokong pill, hereafter HCKP) in rats fed high-fat diet. It was evaluated by measuring the changes of body weight, adipose tissues weight and lipid profiles in serum. Methods : Black soybeans were pickled in vinegar for 15 days to prepare Chokong, at room temperature. For treatment group, HCKP was prepared, which five kinds of medicinal herbs(Rhynchosia nulubilis, Glycyrrhiza uralensis, Zizyphus vulgaris, Atractylodes macrocephala K, Astragalus membranaceus and Cornus officinalis) were added to dried Chokong. Four groups of male Sprague-Dawley rats were fed different diets during 9 weeks: normal diet containing 5%(w/w) com oil, high-fat diet containing 10%(w/w) lard plus 5%(w/w) corn oil (HF), high-fat diet supplemented with 1%(T1) and 5%(T5) HCKP powder, respectively. Results : The T5 group had markedly lower body weight gain and weights of epididymal adipose tissue when compared with HF group. There were significant differences in visceral adipose tissue weights, serum total cholesterol and triglyceride concentrations between the HF and T5 group. Then, the efficacy of powered HCKP on body weight and lipid profiles change in rats fed high-fat diet were induced dose dependantly. Conclusion : These results suggest that the possibility of HCKP, as an antiobese functional formula, by suppression of body weight gain and improved lipid profiles.

Objects : Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. Method : Sleeping time, sleep recordings of EEG, EMG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. Results : 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded ${\beta}$-wave in sleep recordings of EEG. In EMG, there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. Conclusion : These results suggest that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

The following study is the result of herbal teas puffed at different temperatures between $140{\sim}220^{\circ}C$. There was change of single breadth that some carbonization occurs according to rise of processing temperature and crude ash content rises relatively, and crude protein and crude fat content had hardly changed and moisture content decreased. The solid elution rate of the herbal teas appeared by 0.18~0.27% (w/w), it increased as puffing temperature rises. The reason for the increase in solid elution rates is due to the breakage of cross bridges between the raw materials in the herbal tea which are carbohydrates, proteins, lipids and etc. after treatments of physical changes rather than chemical ones. Benzopyrene content happened difference in B(${\alpha}$)P content according to processing temperature, raw material by 0.18~0.24 ppbs.

This study was performed to determine the effect of several herbs on radiation-induced apoptosis in jejunal crypt cells. Longyanrou(Euphoris longana), Suanzaoren(Zizyphus vulgaris), Yuanzhi(Polygala tenuifolia), Rensan(Panax ginseng), Fuling(Poria cocos), Muxiang (Saussurea lappa), Chuanxiong(Cnidium officinale), Baishaoyao(Paeonia lactifolia), Shengma (Cimicifuga heracleifolia), Chaihu (Bupleurum falcatum) and Dongchongxiacao ( Paecilomyces japonica) reduced the frequency of radiation-induced apoptosis(p<0.05). Although the mechanisms of this effect remain to be elucidated, these results indicated that Longyanrou, Suanzaoren, Yuanzhi, Rensan, Fuling, Muxiang, Chuanxiong, Baishaoyao, Shengma, Chaihu and Dongchongxiacao might be useful inhibitors of apoptosis, especially since these are relative nontoxic natural products.

The purpose of this study is to investigate the effects of the herbal Chokong pill (hereafter HCKP) on the liver cell and enzyme activities of serum in rat. HCKP were mixed with pickled black soybeans and five different kinds of medicinal herbs (Rhynchosia nulubilis, Glycyrrhiza uralensis, Zizyphus vulgaris, Atractylodes macrocephala K., Astragalus membranaceus and Cornus officinalis). Four groups of male Sprague-Dawley rats were fed by different diets for 9 weeks: normal diet (Nor), high-fat diet (HF), high-fat diet supplemented with 1% (T1) and 5% (T5) HCKP powder, respectively. Depending on the presence of HCKP in high fat diet, the activities of the blood serum GOT and GPT were decreased. GOT and GPT activities of T1 and T5 were decreased 6.1%, 17.8% and 25.4%, 32.4% compared with HF. On microstructure observing through the transmission electron microscope (TEM) of liver cell, in normal group, a normal large and clear nucleus, rough endoplasmic reticulum (RER) and mitochondria possessing well-defined double outer-limiting membranes were found. However, in HF, it was hard to observe the microstructures in cytoplasm, because of too many fat granules. It showed severely damaged cell, pyknotic nucleus, swollen disintegrating RER and mitochontria loosing the cristae. In T1, there were more repaired liver cells and less fat granules than HF. In T5, there were much less numbers and smaller size of the fat granules than T1, and the morphology was similar to normal cell.

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of medicinal plant extracts on ACE. Fifty medicinal plants were selected and the extracts were prepared by refluxing with 70% methanol. Among the extracts, eleven medicinal plant extracts such as Sedum sarmentosum Bunge, Petasites japonicus(s.et z.) Max, Rubus coreanus, Morus bombycis Koidz, Acorus calamus var. angustatus, Glycyrhiza glabra, Equisetum hyemale, Portulaca oleracea L., Prunella vulgaris var. lilacina Nakai, Sorbus commixta Hedl, Allium thunbergii showed more than 50% inhibitory activities, and Paeonia suffruticosa Andr., lnula helenium, Acanthopanax senticosus Harms, Dendrobium moniliforme, Juglans mandshurica, Zizyphus jujuba, Leonurus artemisia, Aster scaber Thunb, Vitex rotundifolia, Platycodon grandiflorum, Prunus persica, Ligularia fischeri showed $40{\sim}49%$ inhibitory activities. Therefore these extracts which contain high ACE inhibitory activities may be useful as antihypertension agents and to the treatment of hypertension.

The following is the study result of herbal tea roasted at different temperatures between $80{\sim}140^{\circ}C$. Depending on treatment temperature the water content decreased, some carbonization occurred and crude ash content relatively increased. Also crude protein and crude fat decreased little. Solid elution rate of herbal tea showed 0.15~0.32%(w/w) and the rate of solid elution decreased with higher roasting temperature. There was no big change in $80{\sim}110^{\circ}C$ treatment section but the solid elution decreased rapidly in $110{\sim}140^{\circ}C$ section. The reason for decreasing solid elution rate at higher treatment temperature is because the compact inner tissue makes elution difficult. Benzopyrene content (0.29~0.51ppb) showed a tendency to increase with higher treating temperature. From this result, the $B({\alpha})P$ content differed depending on the treatment temperature and raw materials. In case of roasting, the actual inside temperature is around $200^{\circ}C$ but since the surface temperature of the roaster reaches around $2000^{\circ}C$ some portion of $B({\alpha})P$ content was presumed to be produced from the area that came in contact with this surface. When the processing which is a main component of food carbohydrate, protein, fat reason despite serve heat treatment as a whole is to be detected even though the $B({\alpha})P$ in this way is considered to be.
