Absidia panacisoli sp. nov., isolated from rhizosphere of Panax notoginseng.

A strain (SYPF 7183) was isolated from rhizosphere soil of Panax notoginseng in southwest China. Phylogenetic analyses indicated that strain SYPF 7183 was distinct from the other Absidia species with well-supported values. Strain SYPF 7183 produced spherical or subpyriform sporangia and short cylindrical sporangiospores.

[A semimicroquality evaluation method on Panax notoginseng and its application in analysis of continuous cropping obstacles research samples].

Panax notoginseng is a commonly used traditional Chinese medicine with blood activating effect while has continuous cropping obstacle problem in planting process. In present study, a semimicroextraction method with water-saturated n-butanol on 0.1 g notoginseng sample was established with good repeatability (RSD<2.
