This study aimed to explore an analysis method for baicalin in Scutellaria baicalensis Georgi and make a reference for the analysis of the medicinal value of S. baicalensis cultivated in Jizhou District. The content of baicalin in S. baicalensis cultivated in Jizhou District was determined using high-performance liquid chromatography( HPLC) to judge whether it met the requirements of Chinese Pharmacopoeia; and according to the requirements of the Chinese Pharmacopoeia of 2015 edition,the contents of heavy metals were determined by ICP-MS. The results showed that the contents of baicalin,Cr,Cu,As,Cd and Pb in S. baicalensis planted in Jizhou District were 14. 625 05%,11. 360,12. 830,0. 062 315,0. 025 715 and 0. 176 65 μg/g,respectively. The content of baicalin in S. baicalensis planted in Jizhou District was much higher than the standard( ≥ 9. 0%) of Chinese Pharmacopoeia of 2015 edition,and the contents of heavy metals were also below the limit( ≤20/1000 000) required by Chinese Pharmacopoeia of 2015 edition.

Ltd.Tianjin 300451China Management Committee of Tianjin Jinnan National Agricultural Science and Technology Park Tianjin 300356China

The contents of chlorogenic acid and luteoloside in Flos Lonicerae from Binhai New Area and Jinnan District of Tianjin were determined to provide basis for the quality identification of this medicinal material. The content of chlorogenic acid was determined by HPLC. In Flos Lonicerae from Binhai New Area and in Flos Lonicerae harvested at different stages from Jinnan District,the contents of chlorogenic acid were 3. 804%,5. 507%( three green stage),4. 855%( silver flower stage) and 4. 220%( golden flower stage),respectively,and the contents of luteoloside were 5. 53%,12. 405%( three green stage),14. 370%( silver flower stage) and 0. 917%( golden flower stage),respectively. The contents of chlorogenic acid in Flos Lonicerae from Jinnan District were higher than that from Binhai New Area. Among different stages,the content of chlorogenic acid was highest in three green stage,followed by that in silver flower stage. As the flowers bloomed,the content of chlorogenic acid in the medicinal material showed a significant downward trend. In Flos Lonicerae from Jinnan District,the content of luteoloside was highest in silver flower stage and lowest in golden flower stage.

The seeds of tested Angelica sinensis （Oliy.）Diels were purchased from the planting base of Hebsi Anguo Traditional Chinese Medicine Market. With the root tips of germinated Angelica sinensis seeds treated with GA3 as materials, karyotype analysis was performed by photomicrographic technology and conventional chromosome preparation method. The results showed that the chromosome number of A. sinensis was 2 n=2.2, which accords with previous studies; and no satellites were observed, and the chromosome karyotype was 2A, with the asymmetrical karyotype coefficient （AS.K%） of 54：85%. The total length of the chromosomes was 113.4 pro, and total volume of chromosomes was 83.21 μm3.

以二年生知母为试验材料,设4个遮阴处理(0,40%,70%,90%),待知母植株长至50 cm时对其进行光合特性研究。结果表明,随着遮阴程度的增加,知母叶片叶绿素相对含量均不同。70%遮阴处理的知母叶片叶绿素相对含量高于对照(CK),经40%与90%遮阴处理的知母叶片叶绿素相对含量则低于对照(CK)。随着遮阴程度的增加,知母叶片日均净光合速率(Pn)、胞间CO_(2)浓度(Ci)、蒸腾速率(Tr)、气孔导度(Gs)均随之降低,在遮阴度为90%时达到最小值。40%遮阴处理的知母叶片表观量子效率(AQY)高于对照(CK),而70%和90%遮阴处理的知母叶片叶绿素相对含量则低于对照(CK)。遮阴处理降低了知母叶片光饱和点与光补偿点。试验表明,知母适宜在遮阴度较低的林下、林缘以及较干燥或向阳的山坡、草地上生长。人工种植时,要给予知母植株充足的光照,以促进知母高效和高质量生长。
