The differences in metabolites male and female individuals of dioecious Morus alba L. (Moraceae) are usually ignored lack study. In the present study, 58 leaves 61 stem barks from were analyzed by untargeted metabolomics via headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) coupled with chemometrics, including principal component analysis (PCA) orthogonal partial least squares-discriminant (OPLS-DA). A total 66 44 identified barks, respectively. Four...
Abstract A high‐performance liquid chromatography (HPLC) fingerprint method with multivariate statistical analyses was applied to discriminate the male and female barks of Populus tomentosa for first time. The samples 11 13 mature P. were collected in Beijing. chemical methanol extract established by HPLC diode array detector (DAD). principal component analysis (PCA), hierarchical clustering (HCA), supervised orthogonal partial least squares discriminant (OPLS‐DA) based on area common peaks...
Herpetospermum pedunculosum (Ser.) C. B. Clarke (Family Cucurbitaceae) is a dioecious plant and has been used as traditional Tibetan medicine for the treatment of hepatobiliary diseases. The component, content, difference in volatile compounds female male buds H. were explored by using headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) technology multivariate statistical analysis. results showed that isoamyl alcohol was main compound both its content...
To comprehensively evaluate the quality of medicinal and edible Ziziphi Spinosae Semen (ZSS, dried ripe seeds Ziziphus jujuba var. spinosa) before after rancidity during storage, some indicators including traditional sensory properties, physicochemical characteristics, volatile compounds were analyzed. As a result, compared with normal samples, rancid samples ZSS produced darker color, bitter taste, an irritating odor, increased moisture content, electrical conductivity, fatty oil acid...
A high performance liquid chromatography-diode array detector (HPLC-DAD) was used to establish the HPLC fingerprint. Chemometrics methods were discriminate against gender of flower buds Populus tomentosa based on areas common peaks calibrated with The score plot principal component analysis (PCA) showed a clear grouping trend (R 2 X, 0.753; Q 2, 0.564) between female and male samples. Two groups also well discriminated orthogonal partial least squares-discriminant (OPLS-DA) 0.741; R Y,...
1H Nuclear Magnetic Resonance (1H NMR) combined with multivariate statistics was adopted to discriminate female and male flower buds of Populus tomentosa in the study. Samples 11 16 P. were collected Beijing, China. NMR spectra acquired on a 400 MHz spectrometer. In total, 30 chemical compounds identified standards literature according shifts, peak areas, multiplicity. Principal component analysis (PCA), hierarchical clustering (HCA), supervised orthogonal partial least squares-discriminant...
