To investigate the chemical constituents of A. barbadensis, aqueous extract of the plant was subjected to preparative medium pressure liquid chromatography (MPLC). The chemical structures were mainly determined by spectroscopic evidences (UV, IR, HR-MS, 1H NMR, 13C NMR, HSQC, 1H-1H COSY and HMBC) and chemical methods. A new O, O, O-triglucosylated naphthalene derivative, together with two known 6-phenyl-2-pyrone derivatives and four 5-methylchromones, were isolated and identified as 1-((3-((4- O-beta-D-glucopyranosyl)-beta-D-xylopyranosyloxymethyl)-1-hydroxy-8-alpha-L-rhamnopyranosyloxy)naphthalene-2-y])-ethanone (1), 10-O-beta-D-glucopyranosyl aloenin (2), aloenin B (3), aloesin (4), 8-C-glucosyl-(R)-aloesol (5), 8-C-glucosyl-7-O-methyl-(S)-aloesol (6), and isoaloeresin D (7). Compound 1 is a novel naphthalene derivative and named as aloveroside B, compounds 2-3 are isolated from this Aloe species for the first time.

This article was aimed to rapidly analyze chemical composition in A loe Barbadensis Mill, and to compare the chemical composition of commercial aloe vera medicinal materials with that of fresh aloe yellow exudate. An opti-mized liquid chromatography-mass spectrometry-ion trap-time-of-flight (LCMS-IT-TOF) method was applied for the analysis of commercial aloe vera medicinal materials and fresh aloe yellow exudates. The Agilent TC-C18 column (4.6 í 250 mm, 5 m) was used. The gradient elution was a solvent system of water(A)-methanol(B). ESI source was operated in both positive and negative ion modes. The results showed that chromones, pyrones, naphthalene deriva-tive, anthrones and anthraquinones were separated successfully, 30 compounds were characterized by the comparison of characteristic MS/MS fragment ions data with the literature. The diagnostic fragmentation patterns of different chemical compositions were also discussed on the basis of EST-IT-TOF MS data. It was concluded that the chemical composition of commercial aloe vera medicinal materials were significantly different from that of fresh aloe yellow ex-udate in terms of types and contents: the former one mainly contains isoaloeresin D and aloin, and few aloesin; but the latter is mainly composed of aloesin and aloin, and the content of aloesin is the highest. The LCMS-IT-TOF analysis can be used to rapidly obtain rich structural information of different chemical compositions, which improves the efficiency of qualitative analysis of chemical composition, and is of great significance to the quality control, eval-uation and the utilization of A loe Barbadensis Mill.

Aim To investigate the protective mechanism of anisodine hydrobromide against cerebral ischemia-reperfusion injury in rats.Methods In vivo: the cerebral ischemia-reperfusion injury model was established by middle cerebral artery occlusion(MCAO)via suture method in rats;the rats were injected anisodine hydrobromide(1.2,0.6,0.3,0.15 mg·kg-1);the morphological changes were detected by HE staining;the Nissl staining was used to count the number of surviving neurons;the activity of CAT and LDH,the LPO contents in the brain tissue were measured;the expressions of Bax,Bcl-2,caspase-3 and p-Akt in brain tissue were detected by Western blot.In vitro: Western blot assay was used to determine the expression of Bax,Bcl-2,caspase-3 and p-Akt protein expression in the OGD-R model of PC12 cells.The signal pathway of anisodine hydrobromide was identified.Results Anisodine hydrobromide with the dose of 0.15 mg·kg-1 could significantly lessen the morphological changes,and improve the number of surviving neurons;the dose of 0.3 and 0.15 mg·kg-1 could significantly improve the activity of CAT;the dose of 0.3 mg·kg-1 could significantly reduce the contents of LPO in the rat brain tissue;the dose of 1.2 mg·kg-1 could significantly decrease the activity of LDH;the dose of 0.15～1.2 mg·kg-1 could inhibit the expression of Bax,promote the expression of p-Akt in rat brain tissue.All the doses except 0.15 mg·kg-1 could promote the expression of Bcl-2 in rat brain tissue.In vitro,the results showed that anisodine hydrobromide in 25～100 μmol·L-1 could significantly improve the expression of Bcl-2 and the ratio of Bcl-2/Bax,and the dose of 50 μmol·L-1 could significantly improve the ratio of p-Akt/Akt.Conclusion The mechanism of anisodine hydrobromide against cerebral ischemia-reperfusion injury model rats might be related to its anti-oxidative activity and the activation of Akt.
