There is an increased demand of metal back cover mobile devices such as mobile phones, tablets and laptops. This constrains the antenna design and leaves very small area for antennas. Another practical problem seen is reduction in volume available for antennas while number of bands which are supported in these devices are ever increasing. To mitigate these problems we used metal body of the device...
A new halimane diterpenoid, 13-hydroxy-5(10),14-halimadien-6-one (1) and two new labdane diterpenoids, 6α,7α-diacetoxy-13-hydroxy-8(9),14-labdadien (2) and 9-hydroxy-13(14)-labden-15,16-olide (3), were isolated for the first time, along with fifteen known compounds, from the hexane soluble fraction of methanolic extract of Vitex trifolia leaves. The structures of these new diterpenoids were elucidated...
The antitubercular activity of selected flavonoids and their structure–activity relationships were studied against Mycobacterium tuberculosisH37Rv strain radiometrically by BACTEC 460 assay. Present study led to the identification of five flavonoids, viz., luteolin, baicalein, quercetin, myricetin and hispidulin with MIC 25–100 μg ml−1, as...
