But some methods and technologies were hard to transplant. According to the concrete conditions of karst rock desertification in Chongqing, Lippia nodiflora(L.) Greene was introduced as a kind of pioneer plant. By way of the cultivation of introduced practice in Nanchuan District and Wushan County, the phenophase, growth rate and resistibility of Lippia nodiflora were tested. The results show that Lippia nodiflora was suitable for being promoted in karst rock desertification areas, for it’s rapid growth, drought-relief, low death rate and adaptability to calcium in soil.展开更多

Sixteen compounds predominated by monoterpenes were identified. The major compounds were Eucalyptol （28.36%）, α-Terpineol （25.99%）, γ-Terpinene （15.24%）, α-Pinene （5.08%）, 1H-Cyclopropa[a]naphthalene （4.25%） and 1, 3, 6, 10-Dodeeatetraene （3.74%）. Percentage mortality due to fumigant toxicity was dose- and exposure period-dependent. One hour after treatment （HAT）, application of L. adoensis leaf EO at 107 μL· L^-1 air caused significantly （p〈0.05） higher mortality （50.00%） than 0.00% mortality observed at 0-53 μL· L^-1 air, but not significantly （p〉0.05） different from 22.50% observed in 80 μL· L^-1 air. At 3 HAT, application ofL. adoensis EO at 80 μL· L^-1 air caused significantly higher mortality （90.00 %） than mortality observed at 0 μL· L^-1 air. At 6 HAT, application of L. adoensis EO at 53-107 μL· L^-1 air caused significantly higher mortality （100.00 %） than that was observed in the control. The same trend was observed at 12 HAT where 100 % mortality observed in 27-107 μL· L^-1 air was significantly greater than 13.33 % observed in the control. At 3 HAT, percentage repellence was significantly （p〈0.05） affected by doses. Application of EO at 10-30 μL· cm^2 caused class V repellence （86.67%-100%） compared with the control which caused class I repellence （0-20%）.展开更多

Samples of buds, young leaves and broadleaf stems were collected from wild plants of Lippia multiflora in three localities, including two from the Center (Yamoussoukro, Toumodi) and one from the northeast (Bondoukou) of Côte d’Ivoire. The lipid and ash contents were carried out by the AOAC method. The total protein and sugar contents were determined by the Kjeldahl and Agbo methods, respectively. Nine minerals (potassium, calcium, magnesium, iron, sodium, manganese, zinc, copper and cadmium) were quantitated by Atomic Absorption Spectrophotometry (AAS) from green teas (buds and young leaves) and herbal tea of Lippia multiflora. The results showed that ash levels (7.05% - 13.94%) and protein (6.22% - 9.97%) were high, however the lipid contents (1.01% - 2.98%) and total sugars (1.43% - 4.51%) are low. Majority of the minerals are calcium (2320.91 to 36150.10 mg/kg), potassium (2110.71 to 12174.67 mg/kg) and magnesium (3620.87 - 5870.46 mg/kg). Iron (52.55 to 483.11 mg/kg), sodium (35.66 to 469.16 mg/kg) and manganese (15.25 to 76.86 mg/kg) are represented in average proportions. There are small amounts of zinc (9.61 - 47.50 mg/kg), copper (5.66 - 8.71 mg/kg), and cadmium (0.17 - 1.49 mg/kg). Lippia multiflora herbal teas and green teas are low in fat, high in ash and are good sources of protein and minerals.展开更多

Greene were sampled to measure the nutritional indices. The nutritional indices were also compared with common forage grass,and the development value of L. nodiflora as feed was analyzed. Compared with P. nodiflora,L. nodiflora had obvious fast-growing and high-yield abilities. The contents of crude fat,crude fiber,crude ash,lysine,vitamin C,Ca,and Fe in L. nodiflora were obviously higher than that in P. nodiflora,but the content of crude protein and total P in L. nodiflora were significantly lower than that in P. nodiflora. Compared with common forage feed ryegrass,alfalfa,millet straw and corn straw,L. nodiflora had higher contents of crude fat and crude ash and lower contents of crude fiber and crude protein. Therefore,L. nodiflora had higher development value as feed.展开更多

Method: 7 groups of 4 STZ-diabetic rats received separately orally Glucophage<sup>®</sup> (Glu 10 mg/kg), the plant extract (LiMAE 200 - 600 mg/kg) and the plant extract supplemented with magnesium (LiMAE-Mg 200 - 600 mg/kg). After a daily treatment of 21 days, serum biochemical parameters were assayed in 16 hr-fasted rats. Results: Diabetes caused a significant (p Conclusion: The addition of magnesium to the extract of Lippia multiflora caused a greater reduction in the levels of urea, creatinine, ALT and AST increased in STZ-diabetic rats. Magnesium would therefore enhance the nephroprotective and hepatoprotective effects of Lippia multiflora in diabetic rats.展开更多

Chev (Verbenaceae), a medicinal plant used traditionally in the Cameroonian savannah’s region to protect foodstuffs and to cure degenerative diseases. Results indicated that theses extracts contain terpenoids, phenolic and flavonoid compounds. Except the n-hexane extract, all of the obtained extracts exhibit antioxidant activities with the ethanol extract being the most effective with an inhibition percentage of 85.668% ± 1.233% and an inhibition concentration (IC<sub>50</sub>) of 58 μg/ml (R<sup>2</sup> = 0.987, P < 0.01) at a concentration of 100 mg/ml. Chromatographic separation on silica gel of the ethanol extract led to the isolation of a pure organic compound which was characterized as 7-hydroxy-5,6,4'-trimethox- yflavone by extensive 1D and 2D NMR spectroscopy, a flavonoid exhibiting antioxidative activity with an inhibitory percentage of 25.506% ± 0.205% and inhibition concentration (IC<sub>50</sub>) of 221 μg/ml (R<sup>2</sup> = 0.966, P < 0.01). This is the first time that 7-hydroxy-5,6,4'-trimethoxyflavone is being isolated from L. rugosa and its antioxidant activity evaluated.展开更多
