Analytical and bioanalytical chemistry.Anal Bioanal Chem.2015 Feb;407(6):1763-73. doi: 10.1007/s00216-014-8396-1. Epub 2014 Dec 20.
A novel effervescent-salt-assisted dispersive micro-solid-phase extraction using mesoporous hybrid materials was developed for the extraction of minute traces of constituents in complicated plant preparations. In this study, a special tablet containing carbon dioxide sources (sodium dihydrogenphosph

Scientia pharmaceutica.Sci Pharm.2013 Dec 9;82(2):265-79. doi: 10.3797/scipharm.1310-09. eCollection 2014.
Memantine is chemically a tricyclic amine and is used for Parkinson's disease and movement disorders. Although several HPLC methods with different derivatization reagents have been developed for the determination of memantine in biological fluids, there are some complications which limit the use of

Talanta.Talanta.2013 Oct 15;115:336-41. doi: 10.1016/j.talanta.2013.05.042. Epub 2013 May 24.
Understanding the flux and turnover of phosphorus (P) in the environment is important due to the key role P plays in eutrophication and in the ambition to find cost-effective measures to mitigate it. Orthophosphate diesters, including DNA and phospholipids (PLs), represent a potentially degradable P

目的:水酸化カルシウム製剤は早期に被蓋硬組織を形成し,その形成量も多い.しかし強アルカリ性のため,場合によっては広範囲な歯髄壊死を生じることや,被蓋硬組織は裂隙を認め,多孔質であることなどの問題点も指摘されている.一方,リン酸カルシウム化合物からなるα-TCP/Te-CPセメントは,生体親和性が高く,硬組織を誘導する.そこでこのα-TCP/Te-CPセメントに注目し,まず理工学的諸性質を調べ,さら …

生薬學雜誌 57(3), 110-113, 2003-06-20
… An AccuSep capillary column (75 μm i.d.×60cm) was used with a solvent of 40mM sodium dihydrogenphosphate - acetonitrile (9:1, adjusted to pH4.5 with phosphoric acid) as the electrophoretic buffer, and 12.5kV as the electrophoretic voltage, to obtain synephrine from Evodia fruit within about 20min. The same analytical conditions were applicable to the separation of synephrine from decoctions of 8 Chinese medicinal prescriptions. …
