[Effects of soil bulk density on growth, physiology and quality of Glechoma longituba]

Through the determination of the growth, physiological and active components of Glechoma longituba, the effect of soil bulk density on growth and quality of G. longituba was explored. Through pot experiment, six different bulk density treatments were set for 0.8, 0.9, 1.0, 1.1, 1.2, 1.3 g·cm⁻³ , the growth index, physiological index and the content of active components were determined. The results showed that the growth indexes and biomass of G. longituba firstly increased and then decreased with the increase of soil bulk density. The dry weight of G. longituba achieved the maximum 5.70 g in the treatment of 1.0 g·cm⁻³ . The photosynthetic pigments, soluble sugars and free amino acids firstly increased and then decreased with the increase of soil bulk density. The suitable soil bulk density was beneficial to the accumulation of photosynthetic pigment, soluble protein and free amino acid synthesis. The content of malondialdehyde increased gradually with the increase of soil bulk density. The contents of ethanol-soluble extractives of G. longituba were greater than 25%, meeting its quality criterionin Chinese Pharmacopoeia 2015, achieved the maximum of 40.66% in the treatment of 1.0 g·cm⁻³ . The total flavonoids content of G. longituba increased gradually with the increase of soil bulk density, triterpenic acid and phenolic acids decreased gradually with the increase of soil bulk density. Soil bulk density has a significant effect on the growth and quality of G. longituba, and it is conducive to the growth and its medicinal quality at the soil bulk density of 1.0 g·cm⁻³.

[Effects of compound planting on growth and quality of Salvia miltiorrhiza]

The effects of four kinds of different plant populations on the morphology, the dry matter accumulation, active ingredient content and antioxidant activty in vitro of Salvia miltiorrhiza were analyzed by setting up four kinds of mixed planting groups, such as S. miltiorrhiza and Cassia obtusifolia, Capsicum annuum, Perilla frutescens and Zea mays. And through the root isolation treatment, we preliminarily explored the formation mechanism of the four kinds of matching plants of the yield and quality of S. miltiorrhiza, and chose the matching plants suitable for the establishment of the compound population with S. miltiorrhiza,and provided the basis for constructing high efficiency compound planting pattern of S. miltiorrhiza. The results showed that there were significant differences in plant morphology, dry matter accumulation of root, active ingredient content and antioxidant activty in vitro of S. miltiorrhiza in different compound population mixed. The growth and yield of S. miltiorrhiza were unfavorable to the combination planting of Cassia obtusifolia, Z. mays and Salvia miltiorrhiza.The compound planting of P. frutescens and S. miltiorrhiza significantly promoted the growth of S. miltiorrhiza, but significantly reduced the quality of S. miltiorrhiza.The yield and quality of S. miltiorrhiza were significantly improved by the combination of C. annuum and S. miltiorrhiza. Therefore, among the four plants of C. obtusifolia, C. annuum, P. frutescens, and Z. mays, the P. frutescens of Solanaceae is the best matching species for the construction of compound planting group with S. miltiorrhiza.

[Effects of Platycodon grandiflorum/pepper intercropping on root growth, yield and quality of Platycodon grandiflorum]

In order to investigate effects of Platycodon grandiflorum and pepper intercropping on root growth, yield and quality of P. grandiflorum, field experiments were conducted in the soils of continuously cultivated P. grandiflorum for three years. The cultivation model was designed as monoculture and intercropping. The monoculture of P. grandiflorum was denoted as CK and the intercrop association of P. grandiflorum/pepper was arranged as follow: in intercrops every two rows of pepper was planted between every three, four and five rows of P. grandiflorum, respectively, and denoted as JC₃₂, JC₄₂ and JC₅₂. Results showed that taproot length and diameter of P. grandiflorum in intercropping association of JC₃₂ was higher than those of P. grandiflorum in monoculture association. This fact suggested that P. grandiflorum intercropped with pepper facilitated its root growth. Compared with monoculture association, the number of lateral root in intercropping association was significantly decreased and the location of lateral root at taproot also altered. This fact suggested that P. grandiflorum intercropped with pepper enhanced appearance quality of P. grandiflorum root. Total root yield and taproot yield of P. grandiflorum in JC₄₂ and JC₅₂ intercropping associations were increased by 4.88%, 8.91% and 14.23%, 12.92%, respectively, compared with monoculture, while root rot incidence decreased significantly. Compared with JC₅₂ intercropping association, JC₄₂ intercropping association significantly increased total saponin and protein contents of P. grandiflorum, decreased root rot incidence, but did not affect taproot yield significantly. Considering root yield and quality, when P. grandiflorum planted in the soil having continuously cultivated P. grandiflorum for three years, the optimal cultivation model was every two rows of pepper was planted between four rows P. grandiflorum.

[Q-marker of Chinese medicine and metabolic regularity of co-network compatibility and rainbow potential]

The effect of Chinese medicine (CM) compound prescription is the combined action results of single herbs based on the basic theory of Chinese medicine, and its function embodies the characteristics of multi components, multi targets and comprehensive effects. It is difficult to study the therapeutic material, establish quality standards or determine Q-marker, so we can't strictly monitor the quality of the whole process of CM. The identification of Q-marker has a profound influence on the whole process of the pharmaceutical engineering of CM. The scattered effect of CM multi-components is regarded as the integral action of the parent nucleus group by the metabolic rule of co-network compatibility and rainbow potential (CCRP). The rule can be used to communicate the individual components and macro components, to reveal the metabolism of CM in organism body and basic law of information exchange, thus revealing the action law of CM on human body. Through the systematic analysis of the Q-marker's guidance to the development of CM and its relationship with the metabolic rule of CCRP, we try to provide some ideas for the identification of Q-marker.
