Effect of Different Factors on Rooting Characteristics and Survival of Lonicera japonica Thunb

[Objective] The aim was to explore the effects of different factors on rapid propagation and seedling survival of Lonicera japonica Thunb. [Method] The cuttings of 1, 2 or 3 years old, with different length, were soaked in different hormones at different concentrations for different time and planted at different dates. Finally, their rooting rate and survival rate in different treatments were measured and compared. [Result] The rooting rate and survival rate of one-year old cuttings with length of 10-13 cm and planted on September 20 and October 20, 2012 were relatively higher among all the treatments. Hormone treatment could significantly promote the callus formation and accelerate the rooting of the cuttings, and improve their survival rate. The cuttings treated with 120-200 mg/L ABT1 or NAA for 35-45 min had higher rooting rate and survival rate. Among them, the survival rate of cuttings treated with 160 mg/L ABT1 for 35 min was the highest, up to 92.5%. [Conclusion] The study provided basis for improving the survival rate of L. japonica by cuttage, and for optimizing the rapid propagation technique.

Effect of Lonicerae Flos extracts on reflux esophagitis with antioxidant activity

AIM： To observe the effects of traditional antiinflammatory medicine Lonicerae FIos （LF） on rat reflux esophagitis （RE） induced by pylorus and forestomach ligation compared with the well-known proton antioxidant, α-tocopherol. METHODS： Rats were pretreated with three different dosages of LF （500, 250 and 125 mg/kg） orally, once a day for 14 d before pylorus and forestomach ligation. Nine hours after pylorus and forestomach ligation, changes to the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, antioxidant effects, esophageal lipid peroxidation, superoxide dismutase （SOD）, catalase （CAT）, malondialdehyde （MDA）, myeloperoxidase and glutathione （GSH） levels, and collagen contents （marker of flexibility） were observed on the esophageal and fundic histopathology. The results were compared with an α-tocopherol （once orally, 1 h before operation, 30 mg/kg） treated group in which the effects on RE were already confirmed.RESULTS： Pylorus and forestomach ligations caused marked increases of gross esophageal and gastric mucosa lesion areas, which corresponded with histopathological changes. In addition, increases of esophageal lipid peroxidation, decreases of SOD, CAT, and GSH-free radical scavengers, increases of collagen were observed. However, these pylorus and forestomach ligation induced RE were dose-dependently inhibited by treatment of 500, 250 and 125 mg/kg of LF extract, mediated by antioxidant effects. RE at 250 mg/kg showed similar effects α-tocopherol. CONCLUSION： The results suggest that antioxidant effects of LF could attenuate the severity of RE and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Effect of chlorogenic acid on antioxidant activity of Flos Lonicerae extracts

Flos Lonicerae is a medically useful traditional Chinese medicine herb. However, little is known about the antioxidant properties of Flos Lonicerae extracts. Here the antioxidant capacity of water, methanolic and ethanolic extracts prepared from Flos Lonicerae to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and reduce Fe3+ to Fe2+ is examined. Chlorogenic acid, a major component of Flos Lonicerae, is identified and further purified from 70% ethanolic extract with high performance liquid chromatography (HPLC) and its antioxidant capacity is characterized. The total phenolic compounds and chlorogenic acid con-tents in Flos Lonicerae are determined. The present results demonstrate that the Flos Lonicerae extracts exhibit antioxidant ac-tivity and chlorogenic acid is a major contributor to this activity.

Effects of Biochar on Physiological Characteristics of Lonicera Japonica and Accumulation of Cd and Pb in Cd and Pb Contaminated Soil

A pot experiment was conducted to study the effects of biochar on physiological characteristics and accumulation of Cd and Pb of Lonicera japonica in Cd and Pb contaminated soil.The results showed that adding 2%~16%biochar could significantly increase the net photosynthetic rate,chlorophyll content and root activity of Lonicera japonica,and significantly reduce its SOD activity.When 6%~16%biochar was added,the contents of Cd and Pb in roots and stems of Lonicera japonica decreased significantly;when 2%~16%biochar was added,the contents of Cd and Pb in the leaves and flowers of Lonicera japonica decreased significantly.Adding more than 8%biochar can reduce the content of Cd and Pb in Lonicera japonica to a safe range level.

Bainiuchang super-large silver-polymetallic ore deposit related to granitic magmatism in Mengzi, Yunnan

Bainiuchang silver-polymetallic ore deposit is located in the southeast Yunnan tin-polymetallic metallogenic belt.The probable reserves and inferred resources of the deposit are of 6 470 t Ag and 1.10 Mt Pb and 1.72 Mt Zn and 86 kt Sn.Orebodies of the deposit occur in clastic-carbonate rocks of Tianpeng Formation and Longha Formation of the middle Cambrian System above the Bainiuchang concealed granite of the late Yanshan period.The concealed granite has the characteristics of tin-bearing granites.Abundance of the mineralization elements Sn,Cu,Zn,Pb,Ag and Sb is high in the granitic rocks.Sulphur isotope data of the metal sulphides indicate that most sulphur is derived from the magmas.The ores are similar in rare earth element(REE)patterns to the granitic rocks.The granitic magma activity results in ore-bearing structures.Rocks of the Middle Cambrian System above the concealed intrusion suffer from skarnization,hornfelsing,marbleization,siliconizing and carbonatization.The mineralization elements Sn,Cu,Zn,Pb,Ag and Sb successively appear from the top of the granite to surrounding rocks.These evidences indicate that the granitic magmatism is the principal mineralization factor.The opinion that the south Bainiuchang ore field and the north Awei ore block are tin and copper potential exploration areas was put forward and was verified by drilling tests.

Chinese Patent, A Tentative Explanation of Various Strategies of Patenting

The recent increase in patent granted in China prompts for an analysis of the various strategies which are certainly developed by Chinese applicants in that field. An analysis （APA Automatic Patent Analysis） has been done in several fields which have different impacts on the Chinese economy. We chose four different subjects： solar panels; photovoltaic panels; fireworks; and honeysuckle. These areas go from deep international concern to only Chinese interest. We analyzed in the different ratios between Chinese priority patents, Chinese patents extended to other countries, Patent extended from other countries to China and Chinese utility models. The results show clearly that various directions are followed depending on the economic importance of the field and also the pressure of the competition inside and outside China. In this context the strategic dependence （number of patents extended to China by other countries） was examined for each of the fields. We also show that in the domain where the man power is important such as fireworks the number of utility models is important. This suggests that utility models are used to spread in that field minor innovations. In the fields such as honeysuckle many applicants are the same that the inventors and the involvement of universities larger than in other fields. These two fields more or less centered on Chinese domestic aspects only a few patents （not for Honeysuckle） are extended to other countries. The impact of foreign patents in these two fields is quasi nil. In other domains such as photovoltaic panel the triadic patents （extension to US JP EP） are examined its show that if some Chinese patents are extended to other countries there are also an important numbers of foreign patents extended to China. This also suggests that in these most critical subjects, China develops a sort of technological protection barrier from domestic patents. This underlines a strategy on attack and defense in that field.

Qualitative analysis of the chemical constituents of Lonicera japonica and its tetraploid cultivar Jiufengyihao

In the present study, we, for the first time, developed an UPLC-IT-TOF/MS method to compare the chemical constituents of the flower buds of Lonicera japonica Thunb. （Jinyinhua, JYH, in Chinese） and its tetraploid cultivar Jiufengyihao （JFYH）. The samples were separated on a C18 ultra-column （100 mm×2.1 ram, 1.8 μm） eluted with a mixture of acetonitrile and 0.1% formic acid using a gradient program. Based on the accurate masses, fragmental MS2 ions and fragmentation pathway, we unambiguously affirmed or tentatively identified 30 compounds, including 11 phenolic acids, 10 iridoid glycosides, 8 fiavonoids and 1 saponin, from JYH and JFYH. Among them, all compounds were detected in Lonicerajaponica, but only 21 compounds were detected in JFYH. In addition, the relative contents of the 21 common chemical constituents were also different in JYH and JFYH, suggesting an obvious chemical difference between JYH and JFYH.

Simultaneous quantification of ten phenolic acids in Lonicerae Japonicae Flos by HPLC-DAD

A reverse-phase HPLC-DAD method was developed for simultaneous quantification of ten phenolic acids （caffeic acid, chlorogenic acid, neochlorogenic acid, 4-O-caffeoylquinic acid, 3,4-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid, 4,5-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid methyl ester, 3,4-O-dicaffeoylquinic acid methyl ester, and 4,5-0- dicaffeoylquinic acid methyl ester） in the dried flower buds of Lonicera japonica Thunb. （Lonicerae Japonicae Flos; LJF）. An optimal sample preparation method was established as 30-min ultrasonication with 100 times 50% （v/w） ethanol aqueous solution based on the orthogonal test results. The chromatographic separation of the ten phenolic acids was achieved with an AQ-C18 column （4.6 mm x 250 mm, 5 p.m） and a gradient elution of acetonitrile, methanol and 0.1% formic acid aqueous solution within 55 rain. All calibration curves showed good linearity （r2〉0.999） within test ranges. The average recoveries were in the range of 98.57%-103.22% with RSD less than 3%. The method developed was accurate, sensitive and reproducible for determination of ten phenolic acids in LJF.
