We have previously shown that the extract of Emblica officinalis, which is a well-known herb in Ayurvedic traditional medicine, increases the proliferation of keratinocytes. Here we purified a compound that increased cell proliferation from E. officinalis extract. Through liquid chromatography electrospray ionization tandem mass spectrometry and NMR techniques, the compound was determined to be 1,6-digalloyl glucose. Consistent with this, tannic acid, a type of polygalloyl glucose, also increased cell proliferation. We further found that E. officinalis extract increased the proliferation of fibroblasts as well and showed that it increased cell proliferation at least partly through upregulating the expression of periostin.
