Cnidii Monnieri [Cnidium monnieri (L.) Cusson] is one of the most common used herbal plants in the treatment of numerous ailments including reproductive diseases for hundred of years. Total coumarins of Cnidii Monnieri (TCCM) is a key ingredient. Osthole (Ost) and Imperatorin (Imp) are two main effective ingredients enriched in TCCM. The purpose of this study was to investigate the pharmacokine...

A detailed study of the ringed galaxy NGC 3344 ?

We study the relatively isolated galaxy NGC 3344, classified as SABbc, as part of our study of ringed isolated non-barred galaxies. This galaxy shows an inner and an outer ring, together with a small bar inside the inner ring. This bar is too small to relate it directly to the formation of the outer ring and we explore here its origin through HI (WSRT) line data together with broad band BR CCD-...

Biphenyl-3,3′,4,4′-tetra­amine

The title compound, C(12)H(14)N(4), has a crystallographically imposed centre of symmetry. Inter-molecular N-H⋯N hydrogen bonds between amino groups link adjacent mol-ecules into a three-dimensional network where ten-membered hydrogen-bonded rings are observed.

Biphenyl-4-carbaldehyde azine

The complete mol-ecule of the title compound, C(26)H(20)N(2), is generated by crystallographic inversion symmetry. The terminal phenyl ring is twisted by 19.2 (1)° with respect to the adjacent phenyl-ene ring.
