Fig. 6From: Influence of different pretreatments and drying methods on the chemical compositions and bioactivities of Smilacis Glabrae RhizomaContent changes of bioactive compounds in the prepared SGR samples. A PCA score plot for SGR at different sampling times. B OPLS-DA score plot for SGR at different sampling times. C VIP plot for SGR at different sampling times. D The total contents of the four isomers under different pretreatment and drying conditions (Compared with those at 0Â min, significantly increased contents were described as *, and significantly decreased contents were described as #). E The astilbin content of the prepared SGR samples. (*means that the astilbin content of the prepared SGR sample meets the requirement of the Chinese Pharmacopoeia)Back to article page
