Component analysis of nutritionally rich chloroplasts: recovery from conventional and unconventional green plant species

A study of the literature indicates that chloroplasts synthesise a range of molecules, many of which have nutritional value for humans, but as yet no one has established the nutritional credentials of chloroplasts recovered from plant cells. Chloroplast-rich-fractions (CRFs) were prepared from green plant species and the macro- and micronutrient composition compared with the whole leaf materials (WLMs). The results indicated that, on a dry weight basis, CRF material from a range of green biomass was enriched in lipids and proteins, and in a range of micronutrients compared with the WLM. Vitamins E, pro-vitamin A, and lutein were all greater in CRF preparations. Of the minerals, iron was most notably concentrated in CRF. Spinach CRFs possessed the highest α-tocopherol (62 mg 100 g-1 , dry weight (DW)), β-carotene (336 mg 100 g- 1 DW) and lutein (341 mg 100 g-1 DW) contents, whilst grass CRFs had the highest concentration of alpha-linolenic acid (ALA) (69.5 mg g-1). The higher concentrations of α-tocopherol, β-carotene, lutein, ALA and trace minerals (Fe and Mn) in CRFs suggest their potential use as concentrated ingredients in food formulations deficient in these nutrients

Synthesis and structure of allyl and alkynyl complexes of manganese(II) supported by a bulky beta-diketiminate ligand

Reaction of LK (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3)) and MnCl2(THF)(1.5) in THF unexpectedly resulted in the formation of the trinuclear complex LMn(mu-Cl)(2)Mn(THF)(2)(mu-Cl)(2)MnL (1) in good yield. The substitution reactions of 1 with C3H5MgCl and PhCCLi, respectively, provided the monomeric LMnC3H5(THF) (2) and the dimeric [LMn(mu-CCPh)](2) (3) in moderate yield. Complexes 1-3 were characterized by single-crystal X-ray structural analysis. The structures show that compound 1 contains an ideal planar Mn3Cl4 core and a linear Mn-3 trimer, the allyl ligand in 2 is in an eta(1) mode, and there is pi-interaction between the triple bond and the metal center in 3
