[Method]After P.quinquefolium medicinal materials had been digested by HNO3-H2O2, the content of all elements was measured using microwave assisted digestion-inductively coupled plasma-optical emission spectrometer (ICP-OES). [Result] The average recovery rate of all elements ranged from 92.7% to 106.1% with RSD below 4.5%. All elements did not interfere with each other under the optimized experimental conditions, so they could be determined at the same time. It was discovered by principal component analysis that Al, K, Ti, B, Sn, Cd, Na, Mo and Zn were the characteristic elements of P.quinquefolium samples. As for different commercial specifications, Fe and Mn contents were relatively higher, Zn content was at a moderate level and the Cu, Mo and Se content were relatively lower. The contents of inorganic elements were higher in three-year-old samples than in two-year-old and four-year-old samples. Moreover, the contents of inorganic elements in fibrous roots were higher than those in lateral roots. Different processed products of P.quinquefolium contained higher contents of Fe and Mn. Fe content of Red RADIX PANACIS QUINQUEFOLII was significantly higher than that of White RADIX PANACIS QUINQUEFOLII. There was little difference in Mn and Zn contents. Cu, Mo and Se contents were relatively lower in P.quinquefolium samples. [Conclusion] There were no obvious correlations between the contents of 6 essential elements and growth years, harvesting periods and medicinal parts. The roots, stems and leaves of P.quinquefolium contained higher contents of Ca, K, Mg and P, as well as lower contents of Mo, Sr, Ti, Co and Cd. Hg and other toxic metal elements were not found in P.quinquefolium samples. These pointed out that the roots, stems and leaves of P.quinquefolium were safe for human body with nutritional value and medicinal value. Therefore, we suggested developing stems and leaves of P.quinquefolium Red RADIX PANACIS QUINQUEFOLII into commodities for food, medicine and veterinary use every year.

[Objective] To compare the yield of effective parts, effective components and chemical composition from DATURAE FLOS extracts by microwave-assisted extraction (MAE), soaking extraction (SE) and backflow extraction (BE), so as to search the optimal extraction method. [Method] UV and HPLC were adopted to detect the content of total alkaloids, scopolamine and atropine in ethanol extracts of DATURAE FLOS by MAE, SE and BE. And their chemical constituents were investigated by TLC. [Result] The extraction yield of total alkaloids by MAE, BE and SE were 0.42%, 0.38% and 0.32%, respectively. The extraction yield of scopolamine by MAE, BE and SE were 0.24%, 0.24% and 0.13%, respectively. The extraction yield of atropine by MAE, BE and SE were 0.15%, 0.10% and 0.08%, respectively. It was discovered by TLC comparison that there was no significant difference in spots of alkaloids among three methods, that is, all of them showed four similar spots of alkaloids. [Conclusion] Characterized by short time, less solvent consumption, simple operation and high efficiency, MAE can be use to extract alkaloids from DATURAE FLOS. MAE is an environmental and energy-saving new technology which is worthy to be popularized and applied in large scale extraction of alkaloids from DATURAE FLOS.

[Objective] To compare the cold-resistance capabilities of four Ligustrum cultivars. [Method] Based on semilethal low temperature test and low temperature stress test in phytotron, cold-resistance capabilities of two-year-old seedlings of 4 Ligustrum cultivars were compared at leaf-expansion and shoot-growing stage. [Result] At leaf-expansion and shoot-growing stage, the semilethal low temperatures of Ligustrum×Vicaryi Hort., Ligustrum lucidum Ait., Ligustrum japonicum Thunb. 'Howardii' and Ligustrum lucidum Ait. 'Excelsum Superbum' were -6.34, -5.69, -4.55 and -3.27 ℃, respectively. SOD activity, soluble protein content, soluble sugar content and MDA content in leaves under low temperature stress were all higher than those under normal temperature. As the low temperature stress enhanced, soluble protein content in leaves firstly enhanced and then decreased. Among the 4 cultivars, soluble sugar content in 3 cultivars firstly increased and then decreased; and MDA content continuously enhanced. [Conclusion] The cold-resistance capabilities of Ligustrum×Vicaryi Hort. and Ligustrum lucidum Ait. were higher than other cultivars; Ligustrum japonicum Thunb. 'Howardii' was middling; and Ligustrum lucidum Ait. 'Excelsum Superbum' was the worst.
