Phytochemical investigation of the aerial parts of Leonurus japonicus led to the isolation of one new labdane diterpenoid, leojaponin D （1） and two new ionone derivatives, leojaponones A and B （2 and 3）, together with seven known diterpenoids （4-10）. Their structures were elucidated by extensive 1D and 2D NMR spectroscopic data and by comparison with data reported in the literature. Selected isolates were evaluated their effects on lurkat IL2 secretino.

Objective To study the chemical constituents from the aerial parts of Hypericum beani/. Methods Various chromatographic techniques were used to separate the constituents and their structures were elucidated on the basis of extensive spectroscopic interpretation. Results Fifteen compounds were isolated from the aerial parts of H. beanii. Their structures were identified as hyperbeanol E （1）, （E）-Iinalool-l-oic acid （2）, （4S,5R）-5-（4＇-methyl-3＇-pentenyl）-4-hydroxy-5-methyl- dihydrofuran-2-one （3）, benzoic acid （4）, 4-（3-O-3＂）-3＂-methylbutenyl-6-phenyl- pyran-2-one （5）, 4-hydroxy-4a,7-dimethoxy-4,4a-dihydrodibenzo-p-dioxJn-2（3H）- one （6）, isoimperatorin （7）, 2,3-dimethoxyxanthone （8）, 3,4-dihydroxy-2- methoxyxanthone （9）, osajaxanthone （10）, nigrolineaxanthone F （1 1）, hypercohone G （12）, betulinic acid （1 3）, oleanolic acid 3.13-caffeate （14）, and isoastilbin （1 5）. Conclusion Compound 1 is a new menthane monoterpene derivative which owns an extra lactone ring. Compounds 2-7 and 10-1 5 are isolated from genus Hypericum Linn. for the first time and the other compounds are first obtained from the plants in H. beanii.
