In this study, the chemical constituents of bulb from Lilium lancifolium and Lilium tsingtauense were investigated. The content of moisture, crude protein and fiber of bulb from L. tsingtauense was higher than that of L. lancifolium, whereas the content of crude ash and nitrogen free extract of bulb from L. lancifolium was higher than that of L. tsingtauense. HPLC analysis revealed that total free sugar and amino acid content of bulb from L. tsingtauense was higher than that of L. lancifolium. There was no remarkable difference in proximate composition between the two species. The content of p-coumaric acid and ferulic acid was 1.93 mg% and 0.25 mg% in ethyl acetate fraction of L. lancifolium, on the other hand, 2.94 mg% and 0.46 mg% in ether fraction of L. tsingtauense. These results suggest that the bulb of L. tsingtauense can be considered as promising oriental medicine resource likewise L. lancifolium.
-This study was carried out to effect on Growth Characteristics and Yield of Solanum njgrum L. The experimental results are summarized as follows. Germination, growth characteristics and yield of Solanum nigrum Linne collected from southern parts of Korea were investigated. The one fruit weight was the heaviest in Gochang traditional S. nigrum among the collected sites. The number of seeds in one fruit was high in the orders of Gochang traditional sites, Gwangju traditional sites, Suncheon traditional sites and Naju traditional sites. The earliest flowering of Solanum nigrum was observed on 10. August. The plant height, stem diameter, leaf numbers and branch numbers were ranged from 65 cm to 75 cm, 7.1 mm to 8.2 mm, 237 ea to 270 ea and 12 ea to 17 ea, respectively. The fresh weight per plants were ranged from 265 g to 279 g, and yield of biomass were ranged from 1,298 kg to 1,367 kg per 10a. The insect pest numbers of S. nigrum according to the collected sites were showed no significant in this test.
The antibacterial activity of three Cupressaceae plants (Thujaoccidentalis,ThujaorientalisandChamaecyparisobtusa) was tested against three bacteria using the agar diffusion method. The ether and ethylacetate fraction of crude methanol extract from the three plants showed potent antibacterial activity against the tested microorganisms. The result showed that Staphylococcus aureus revealed the most sensitivity among the tested bacteria. Thujaoccidentalisether fraction and Thujaorientalis hexane fraction exhibited the highest antibacterial activity against Staphylococcus aureus. E. coli was shown the highest MIC values compared to the other two tested bacteria, which indicates the lowest antibacterial activity against the bacterium. This study promises an interesting future for designing a potentially active antibacterial agent from the three Cupressaceae plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
