RESUMO

There are two source plants for the traditional Chinese medicine Murrayae Folium et Cacumen (MFC) in Chinese Pharmacopoeia, i.e. Murraya exotica L. and M. paniculata (L.) Jack. Herein, a chemical comparison of M. exotica and M. paniculata by high performance liquid chromatography (HPLC) fingerprint analysis coupled with chemometrics and network pharmacology was performed. The main peaks in the fingerprints were identified by liquid chromatography coupled with ion trap/time-of-flight mass spectrometry (LC-IT-TOF-MS) and authenticated by references. The chemometrics results showed that the HPLC fingerprints of these two species were clearly divided into two categories using hierarchical cluster analysis (HCA) and principal component analysis (PCA), and a total of 13 significantly differentiated markers were screened out by orthogonal partial least squares-discriminant analysis (OPLS-DA). However, the following network pharmacology analysis showed that these discriminated markers were found to act via many common targets and metabolic pathways, indicating the possibly similar pharmacological effects and mechanisms for M. exotica and M. paniculata. The above results provide valuable evidence for the equivalent use of these two plants in clinical settings. Moreover, the chromatographic fingerprint analysis coupled with chemometrics and network pharmacology supplies an efficient approach for the comparative analysis of multi-source TCMs like MFC.

RESUMO

Phytochemical investigation on Ilex asprella stems by using various chromatographic techniques led to the isolation of 18 phenolic constituents. Based on spectroscopic data analyses and/or comparison of the spectroscopic data with those in literature, these constituents were identified, including two lignans (1, 2), five phenylpropanes (3-7), six chlorogenic analogues (8-13), and five benzoic analogues (14-18). Among them, compounds 3-7, 9, 11, 13, 14, 17, and 18 were isolated from genus Ilex for the first time, and 2, 8, 10, 15, and 16 were isolated from this species for the first time. The in vitro anti-inflammatory assay results showed that compounds 8, 9, 11, 13, and 15 possessed moderate inhibition on the NO production in RAW264.7 cells with IC50 values of 51.1-85.8 µmol·L⁻¹. The present study brought preliminary reference for the clarification of therapeutic ingredients of I. asprella with anti-inflammatory efficacy and its quality evaluation.

RESUMO

Three new triterpenoid saponins, namely asprellinoids A-C (1-3), featuring a sulfate substitution in sugar moiety, were isolated from the stems of Ilex asprella (Hook. et Arn.) Champ. ex Benth. Their structures were elucidated by the spectroscopic data analyses including HR-ESI-MS, IR, and NMR spectra, and chemical method.

RESUMO

Phytochemical investigation on the stems of Ilex asprella by using various chromatographic techniques led to the isolation of 13 compounds. By spectroscopic analyses and comparisons the spectral data with those in literatures, these compounds were identified as salicifoneoliganol(1), rel-(7R,8S)-3,3',5-trimethoxy-4',7-epoxy-8,5'-neolignan-4,9,9'-triol 9-ß-D-glucopyranoside(2),(+)-cycloolivil(3),(+)-syringaresinol-4'-O-ß-D-monoglucoside(4), liriodendrin(5), caffeic acid (6), 3,4-dihydroxy-5-methoxybenzaldehyde(7), benzene-1,2,4-triol(8), 3,4,5-trimethoxyphenyl-1-O-ß-D-apiofuranosyl(1″→6')-glucopyranoside(9), aeculetin(10), cryptochlorogenic acid ethyl ester(11), chlorogenic acid ethyl ester(12), and rel-5-(3S,8S-dihydroxy-1R,5S-dimethyl-7-oxa-6-oxobicyclo [3,2,1]oct-8-yl)-3-methyl-2Z,4E-pentadienoic acid(13). Among them, compounds 7, 8, 11, and 13 were isolated from genus Ilex for the first time, and 1-3, 9, 10, and 12 were isolated from this speciesfor the first time. The anti-inflammatory assay results of these compounds showed that compounds 1 and 9 showed moderate inhibitory effect against NO production in RAW 267. 4 cells with IC50 values of 35.7 and 50.6 µmol•L⁻¹, in vitro respectively, whereas compound 10 showed weak inhibition(IC50 value 98.7 µmol•L⁻¹).

RESUMO

Two new prenylated benzoic acid derivatives, leptoic acid A and (+)-S-anodendroic acid (1-2), along with one known compound, 2,2-dimethyl-2H-1-benzopyran-6-carboxylic acid (3) were isolated from the stem of Euodia lepta (spreng.) Merr. Their structures were elucidated on the basis of the chemical and spectroscopic evidence.
