Apart from being used as food, seed oils have also been used traditionally as medicinal products by several communities. However, the full medicinal potential of many seed oil plants is yet to be properly reviewed, particularly for their antimicrobial and antioxidant properties. North-East India has rich resources of seed oil plants. The availability of detailed information on these plants is quite limited. This review aims to explore and evaluate these seed oil plants of the North-East India with particular emphasis on their antimicrobial and antioxidant activities as well as chemical compositions. A comprehensive literature search on seed oil plants of this region has been performed. Seed oil yielding plants of this region can be categorized into two categories: plants that are used traditionally as sources of edible or medicinal oils and plants that are used for purposes other than as sources of oils. Many seed oil plants of this region have been reported to possess antimicrobial and antioxidant properties, and to produce various types of compounds. This review also highlights the importance of these plants in contributing to the local as well as the national economy of India.

Seed germination and seedling growth of a halophyte, Suaeda japonica were examined to measure the effects of seed preservation periods and various soil compositions in the mudflat of Saemangeum, Korea. Seed germination declined from 74.30% to 44.30% as the preservation period increased from 4 months to 12 months. After 14 days of seeding, seed germination was lowest in sandy soil (SS) at 8.67% and highest in earthworm cast+leaf mold (EC+LM) at 67.33%, showing 4~5 times higher than SS. The average lengths of seedlings were 12.20 mm in SS and 42.20 mm in EC+LM, respectively. These results suggest that seed germination and seedling growth enhanced in the soil that has more organic matter. In the experiment mixing Saemangeum soil (SMS), seed germination was from 4.00% in SMS to 88.00% in the soil of SMS+EC+LM after 14 days. Similar growth patterns were observed in the length of seedlings from 5.00 mm in SMS to 49.60 mm in SMS+EC+LM. The present results indicate that a population of Suaeda japonica could be established by stimulating seed germination and seedling growth by the addition of organic matters such as EC, LM, and EC+LM in the Saemangeum mud flat.

This studies were conducted to find out the possibility of utilizing red pepper seed as resources of food fats, the research method was designed to make a comparison between crude and refined oil, and the results of the studies are as follows : The red pepper seed contained 28% of crude fat and 21% of crude protein. The main fatty acids of red pepper seed oil were linoleic acid(72.10~72.31%), palmitic acid(12.81~13.28%) and oleic acid(9.47~10.48%). The linolenic acid content was so small that is will not influence the autoxidation of the red pepper seed oil. The major triglyceride type of crude and refined oil of red pepper seeds were C52 and C54. The other types were found in a small quantity. The sterol composition of crude oil was $\beta$-sitosterol, campasterol, stigmasteral and brassicasterol,in the quantity order. after refining, brassicasterol was not detected, and the content was decreased by one six and one eight. The toropherol composition of crude and refined oil, tocopherol analog was composed of three kinds $\alpha$-, ${\gamma}$-, $\delta$-, but no $\beta$-form. the quantity of ${\gamma}$-, $\alpha$- and $\delta$-tocopherol were 162.91, 83.72, 43.98mg% respectively. The Quantity of and capsaicin in crude oil was 1,296 ppm, and it was reduced consicerably by refining and removed completely after the process of redeodorization.

This study was performed in order to analyze influences the actual vegetation between the communities of Pinus densiflora and Quercus mongolica in southern Korea to the species composition of the seed bank in the top soil. The soil samples were collected from the studied plots and transported to the Experimental Glasshouse at Department of Landscape Architecture, Yeungnam University and examined the germinated species individual numbers with species composition and germinated individual numbers by species. The overall germination status was the highest in the herbaceous layers than the layers of tree, sub-tree and shrub, respectively. There were no significantly different between numbers of species and individuals and between actual vegetation and seed bank in the two communities. The woody species marked in the seed bank as a pioneer or edge species than in the two communities which are in the stage of mid or late successional species. Although the plant species in the herbaceous layers was highly influenced to the species composition of the seed bank, but no significantly different was showed within the same forest zone and latitudes of Korean peninsula. As the pioneer or edge species of the actual vegetation possibly will be higher the buried in the top soil layer and this phenomenon will influence overall species composition in the seed bank population.

In order to analyze the composition of fatty acid in the seed oil. and amino acid in the seed protein of wild thornless chinese pepper tree; Zanthoxylum schinifolum var. inermis Nakai. GLC method and amino acid autoanalyzer were applied. respectively. while the general composition of the seed and physico-chemical properties of the seed oil were also determined by A. O. A. C. method. The results obtained were summarized as follow The content of oil, protein and ashes were 47.05%, 20.14% and 3.1%, respectively. The content of sulfur and cyan compound in the seed were 0.02% and 0.00005%, respectively, which were far below than allowed guantity by food regulation. Therefore, it is considered to be safe for edible purpose. The iodine absorption number obtained was 145.2, which might be belonged to drying oil. The physico-chemical properties of the seed oil such as acid value, saponification number and refractive index showed the characteristics of an unsaturated high molecular fatty acid compound. The seed oil was composed of 34.8% of oleic acid, 25.1% of linoleic acid and 26.1% of linolenic acid, which accounts for more than 80% of essential fatty acid. Therefore, it could be used as an edible oil. Seventeen kinds of amino acids were anayzed from seed protein. Among them comparatively high content of threonine, valine, methionine, isoleucine, leucine and phenylalanine were observed. As a non-essential amino acid, glutamic acid was found as high as 4.985%. From these results the seed of thornless Chinese pepper would be good for oil and protein source.

This study investigated mineral element concentrations of acorns in Quercus acutissima and Quercus serrata seed orchard, so that to estimate the variation of these species based on the chemical composition in different clones from plus trees. The acorns were collected from ten clones of each species grown in the same clonal seed orchard. The nutritional concentration of acorns was significantly different between the clones and species. The concentration of nutrient for the whole acorn followed in this general sequence: P > K > Na > Mg > Ca > Mn > Fe > Zn > Cu. The mineral concentrations of acorns in clones of Q. acutissima and Q. serrata contained P (494 to 684 and 541 to 672 mg/100 g), K (114 to 569 and 140 to 251 mg/100 g), Na (57 to 121 and 49 to 85 mg/100 g), Mg (29 to 37 and 26 to 42 mg/100 g), Ca (10 to 53 and 26 to 68 mg/100 g), Mn (0.5 to 3.4 and 1.8 to 4.5 mg/100 g), Fe (0.7 to 1.1 and 0.0 to 2.2 mg/100 g), Zn (0.34 to 0.81 and 0.38 to 0.84 mg/100 g), and Cu (0.13 to 0.40 and 0.09 to 0.34 mg/100 g) respectively. Even though acorns of Q. serrata are smaller in size than Q. acutissima, acorns of Q. serrata contained significantly higher concentration of phosphorus, calcium, iron and manganese than Q. acutissima. Based on the mineral composition of the acorns, this study has shown that the clones of Q. acutissima and Q. serrata have different ability to accumulate mineral nutrients which could indicate the variation of Quercus species in terms of mineral acquisition and accumulation.

Background: In this study, the fermentation of ginseng seeds was hypothesized to produce useful physiologically-active substances, similar to that observed for fermented ginseng root. Ginseng seed was fermented using Bacillus, Pediococcus, and Lactobacillus strains to extract ginseng seed oil, and the extraction yield, color, and quantity of phenolic compounds, fatty acids, and phytosterol were then analyzed. Methods: The ginseng seed was fermented inoculating 1% of each strain on sterilized ginseng seeds and incubating the seeds at $30^{\circ}C$ for 24 h. Oil was extracted from the fermented ginseng seeds using compression extraction, solvent extraction, and supercritical fluid extraction. Results and Conclusion: The color of the fermented ginseng seed oil did not differ greatly according to the fermentation or extraction method. The highest phenolic compound content recovered with the use of supercritical fluid extraction combined with fermentation using the Bacillus subtilis Korea Food Research Institute (KFRI) 1127 strain. The fatty acid composition did not differ greatly according to fermentation strain and extraction method. The phytosterol content of ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method was highest at 983.58 mg/100 g. Therefore, our results suggested that the ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method can yield a higher content of bioactive ingredients, such as phenolics, and phytosterols, without impacting the color or fatty acid composition of the product.

The chemical characteristics of seed oils of Asian ginseng (Panax ginseng C.A. Meyer) at different ages grown in Korea (3, 4 and 5-year old) and China (5-year old), and American ginseng (Panax quinquefoliu L., 5-year old) grown in China were compared. Total fatty acid composition showed a significantly higher oleic acid content in American (87.50%) than in Korean (68.02~69.14%) and Chinese ginseng seed oils (61.19%). At the sn-2 position, the highest oleic acid (81.09%) and lowest linoleic acid (15.77%) were found in American ginseng seed oil. The main triacylglycerol species in ginseng seed oils were triolein (OOO) and 1,2-dioleoyl-3-linoleoyl-glycerol (LOO)/1,3-dioleoyl-2-linoleoyl-glycerol (OLO). In addition, the seed oils possessed an ideal oxidative stability showing 16.55~23.12 hr of induction time by Rancimat test. The results revealed that ginseng seed oil could be developed as a new healthy edible oil, and that the oil's chemical characteristics were strongly associated with the ginseng species and habitats.

Soybean [Glycjne max Merr. L.] variety 'Danyeobkong' was inoculated with soybean mosaic virus SMV-G5H strain in field and green house at Crop Experiment Station in 1995. The effects of this virus strain on plant characteristics and seed chemical composition of the soybean variety Danyeobkong were evaluated. Yield, the number of pod and 100 seed weight were significantly reduced by SMV-G5H strain infection. Inoculation of SMV-G5H strain of soybean mosaic virus caused the increment of seed protein content and the decrement of seed oil content in the soybean variety Danyeobkong. Changing pattern of fatty acid composition by SMV-G5H strain infection was varied according to the experimental place. In field trial, the percentage of linoleic and linolenic acids decreased and stearic and oleic acids increased in the seed oil from virus infected plants. In green house trial, however, linolenic and oleic acids were increased, whereas palmitic and linoleic acids were reduced.
