RESUMEN
Moutan Cortex is one kind of famous medicinal materials. The dry root bark of Paeonia ostii which is a genuine medicinal material produced in Tongling,Anhui province,and later was introduced to Heze,Shandong province and Bozhou,Anhui province.Dangshan county is located at the northern end of Anhui province and adjacent to Shandong province. Its medicinal seedlings were came from Heze,Shandong province. At present,there is a lack of scientific investigation on the planting area of P. ostii in north China plain. On the basis of field investigation and remote sensing technology,through the data source provided by the remote sensing image of " Resources 3"( ZY-3),combined with the biological characteristics of P. ostii,the planting area of P. ostii in Dangshan county was extracted by field investigation and supervisory classification. The supervise classification method with the highest interpretation accuracy so far,the overall accuracy was 97. 81%,Kappa coefficient 0. 96. The results showed that the remote sensing classification method based on the maximum likelihood classification could extract P. ostii plots in the study area effectively. This study provides a scientific basis for the protection and rational utilization of traditional Chinese medicine resources,the development policy of traditional Chinese medicine industry and the long-term development plan in Dangshan county,and provides technical support for the poverty alleviation of traditional Chinese medicine industry in Dangshan county. It provides scientific reference for the application of remote sensing technology to investigate the planting area of P. ostii in in north China plain.

Objective To study the secondary metabolites of endophytic fungus Fusarium oxysporum form Paeonia ostii. Methods The fermentation liquor of the fungal strain F. oxysporum were isolated and purified using various chromatographic methods. The structures of the compounds were identified by spectrum analysis. Results Twenty-three compounds were isolated from the fungal and their structures were identified as (2S)-proline (1), (22E,24R)-ergosta-7,22-diene-3β,5α,6β-triol (2), cyclo-(S-Pro-S-Leu) (3), cyclo-(L-Ala-L-Pro) (4), cyclo-(Val-Pro) (5), cyclo-(R-Pro-S-Phe) (6), cyclo-(D-cis-Hyp-L-Phe) (7), cyclo-(trans-4-hydroxy- L-Pro-L-Phe) (8), cyclo-(Gla-Tyr) (9), cyclo-(trans-4-hydroxy-L-Pro-L-Leu) (10), L,L-cyclo-(Trp-Pro) (11), cyclo-(L-Leu-Gly) (12), N-(3-(1H-indol-3-yl)propyl)acetamide (13), indole-3-acetic acid (14), 2-piperidone (15), 2-pyrrolidinone (16), thymidine (17), (5S)-5-[(4-hydroxyphenyl)methyl]-2,4-imidazolidinedione (18), (3S,6S)-3-(butan-2-yl)-6-(1-hydroxyethyl) piperazine-2,5-dione (19), cyclo-(Ala-Leu) (20), cyclo-(S-Pro-S-Phe) (21), cyclo-(Tyr-Pro) (22), and cyclo-(L-Phe-L-Tyr) (23). Conclusion With the exception of compounds 2, 6, and 14, the other compounds are isolated from the fermentation liquor of the fungal strain F. oxysporum for the first time.
RESUMEN
OBJECTIVE: To study the chemical constituents from the seed cake of Paeonia ostii. METHODS: Chemical constituents were isolated by Sephadex LH-20, preparative HPLC, and silica gel column chromatography. The structures were elucidated on the basis of spectral data analysis. RESULTS: Three compounds, 4, 9-dihydroxy-8, 10-dehydrothymol-1-O-β-Z)-glucoside(1), 6′-O-β-Z)-glucopyranosylalbiflorin(2), and paeonidanin(3), were isolated from the seed cake of P. ostii. CONCLUSION: Compound 1 is a new compound, and compounds 2 and 3 were isolated from the seed cake of P. ostii for the first time.

OBJECTIVE: To study the chemical constituents of the seed cakes of Paeonia ostii. METHODS: Chemical constituents were isolated by Toyopearl HW-40, Sephadex LH-20, preparative HPLC, and silica gel column chromatographies. The structures were elucidated on the basis of spectral data analysis. RESULTS: Seven monoterpene glucosides, paeoniflorin (I), oxypaeoniflorin (II), abiflofin(III), 4″- hydroxylalbiflorin(IV), 1-O-β-D-glucopyransoylpaeonisuffron(V), β-gentiobi-osylpaeoniflorin(VI), and abiflofin R1 (VII) were isolated from the seed cake of Paeonia ostii. CONCLUSION: All the compounds are isolated from the seed cakes of Paeonia ostii for the first time.
