The reports on chemical constituents of Hyoscyamus niger were summarized. The compounds include alkaloids, saponins, lignans, coumarinolignans, flavonoids, and some other nonalkaloidal compounds. TLC, HPLC, and GC were used for the qualitative and quantitative analyses of some chemical constituents in H. niger. Modern pharmacological experiments showed that H. niger had the analgesic, anti-inflammatory, antipyretic, anticonvulsant, spasmolytic, antidiarrhoeal, antisecretory, bronchodilatory, urinary bladder relaxant, hypotensive, cardiosuppressant, vasodilator, antitumor, and feeding deterrent properties. In addition, the toxicities of this medicinal plant were also described.

ObjectiveTo identify and analyze the volatile constituents in the leaves and fruits ofFicus carica.MethodsGas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used.ResultsThe major components detected in volatile oil of the leaves were psoralen (10.12%),β-damascenone (10.17%),benzyl alcohol (4.56%),behenic acid (4.79%),and bergapten (1.99%),etc.The major components detected in volatile oil of the fruits were furfural (10.55%),5-methyl-2-furaldehyde (10.1%),and benzeneacetaldehyde (6.59%),etc.Conclusion A total of 121 volatile constituents are identified in the leaves and 108 in the fruits ofF.carica,among which 103 constituents are identified for the first time in the leaves and 100 in the fruits.Eighteen volatile constituents are identified in both leaves and fruits.
