“…The exudate from Azadirachta indica (neem gum) has a high protein content (35%). Fractionation on gel columns supported the view that the protein and polysaccharide were combined; this is consistent with the significant level of hydroxyamino acids in hydrolysates of specimens of this and certain other gums (323,324). Major structural units are 23 and 38.…”

“…The first two foods provide mostly carbohydrates [Anderson et al, 1972;Anderson & Gill, 1975;Coimbra-Filho & Mittermeier, 1976;Bearder & Martin, 1980], whereas their animal prey are the principal source of protein [Martin et al, 1976]. C. geoffroyi showed two peaks in gum consumption over the course of the day, around 0800 hr (higher) and 1500 hr (lower).…”

The potential hepatoprotective activities of two Lannea species were explored in vivo. Furthermore, the binding activities of their main polyphenols to the antiapoptotic protein Bcl-2 were investigated. Based on HPLC-MS/MS results, 22 secondary metabolites were characterized in L. stuhlmannii (mainly tannins), while 20 secondary metabolites (mainly sulphated tannins) were identified in L. humilis. Both extracts exhibited substantial antioxidant activities in vitro and counteracted D-galactosamine induced intoxication in rats in vivo and increased the total antioxidant capacity (TAC) of liver tissues. In addition to reducing the elevated levels of AST and total bilirubin, both extracts significantly attenuated the deleterious histopathologic changes in liver after D-galactosamine-intoxication. Also, both extracts protected hepatocytes from apoptotic cell death and increased the expression of the anti-apoptotic protein Bcl-2. The identified compounds from both extracts can bind to the Bcl-2: Bim (BH3) interface with an appreciable binding free energy. Hydrogen and ionic bonds and hydrophobic interactions with amino acid residues in the hydrophobic face of Bim (BH3) domain were discovered. To sum up, L. humilis and L. stuhlmanni exhibited promising hepatoprotective activities in vivo against D-GalN-induced liver injury and their hepatoprotection is due to the antioxidant and anti-apoptotic effects of tannins and proanthocyanidins.
