“…When high amounts of the procyanidin fraction were added to a C 18 column, their peaks in the elution profile shifted to lower retention times. This effect, caused by high concentrations, is reversible and may be due to the formation of polar complexes of small oligomers between themselves or with high molecular weight compounds [2]. Retention time of each of the compounds in the mixture of standards was determined and their percent relative standard deviation (%RSD) was calculated.…”

“…Possible applications for pine bark are antiradical, antioxidant and anti-inflammatory properties and are marketed as food supplement and an herbalbased medication. Tannins from pine bark have been used to make wood adhesives and foams [2]. Pine bark is mainly composed of polysaccharides (cellulose and hemicellulose) and lignin, as well as minerals such as oxalates, phosphates, silicates, boron, copper, and manganese [3].…”

“…Tanin merupakan substansi terpenting yang ada di dalam tumbuhan, terdapat pada bagian kayu, kulit kayu, daun buah, dan akar, yang terjadi secara alami (Mekonnen et al, 2013) dan digunakan sebagai bahan penyamakan kulit (Vieira et al, 2011;Chupin et al, 2013). Selain adanya material tanin dalam tumbuhan, terdapat pula material non tanin antara lain lemak, lilin, resin, terpenoid, asam uronat, pektin, dan protein (Burkhardt et al, 2013).…”

“…Tanin merupakan substansi terpenting yang ada di dalam tumbuhan, terdapat pada bagian kayu, kulit kayu, daun buah dan akar, yang terjadi secara alami (Musa & Gasmelseed, 2012;Mekonnen et al, 2013;Haroun et al, 2013b) dan dapat digunakan sebagai bahan untuk penyamakan kulit (Vieira et al, 2011;Chupin et al, 2013). Tanin secara ilmiah didefinisikan sebagai senyawa polifenol (Ucar et al, 2013;Haroun et al, 2013a;Bharudin et al, 2014) yang mempunyai berat molekul tinggi (500-3000 Da), terdiri atas elemen C, H, O dengan formula empirik C 76 H 52 O 46 dan mempunyai gugus hidroksil dan gugus lainnya (seperti karboksil) sehingga dapat membentuk ikatan-ikatan hidrogen dengan kolagen dan membuat matrik polyphenolic tanning dan makromolekul lainnya di bawah kondisi lingkungan tertentu (Danarto dkk., 2011;Duki et al, 2013).…”
