ABSTRACT

Paris polyphylla var. chinensis(PPC) is used as one of the origin plants of Paridis Rhizoma described in the Chinese Pharmacopoeia(2020 edition). Its resources shortage makes the planting scale gradually expand, and plenty of aerial parts are abandoned because of not being effectively used. On the basis of previous research, this study separated steroidal saponins to further clarify the chemical composition of the aerial parts of PPC. As a result, three pairs of 25R or 25S epimers of furostanol saponins were obtained by various column chromatography techniques. Their structures were identified as neosolanigroside Y6(1), solanigroside Y6(2), neoprotogracillin(3), protogracillin(4), neoprotodioscin(5) and protodioscin(6) by spectral data combining with chemical transformation. Compound 1 is a new compound, and compounds 2, 3 and 5 are isolated from Paris plants for the first time. Compounds 4 and 6 are isolated from this plant for the first time. Previously, only several spirostanol glycosides with 25S configuration were isolated from Paris plants. Guided by mass spectrometry, the present study isolated the furostanol saponins with 25S configuration from this genus for the first time, which further enriches the chemical information of Paris genus and provides a reference for the isolation of similar compounds.

ABSTRACT

Paridis Rhizoma(PR) is prepared from the dried rhizome of Paris polyphylla var. yunnanensis(PPY) or P. polyphylla var. chinensis(PPC) in Liliaceae family. The rapid development of PPY or PPC planting industry resulted from resource shortage has caused the waste of a large number of non-medicinal resources. To clarify the chemical compositions in rhizomes, fibrous roots, stems, leaves, seeds and pericarps of PPC, and explore the comprehensive application value and development prospect of these parts, the qualitative and quantitative analyses on the different parts of PPC were carried out by ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) and high performance liquid chromatography(HPLC). A total of 136 compounds were identified, including 112 steroidal saponins, 6 flavonoids, 11 nitrogen-containing compounds and 7 phytosterols. Rhizomes, fibrous roots, and seeds mainly contained protopennogenyl glycosides and pennogenyl glycosides; leaves and stems mainly contained protodiosgenyl glycosides and diosgenyl glycosides; pericarps mainly contained pennogenyl glycosides, followed by diosgenyl glycosides. The total level of four saponins was the highest in fibrous roots and rhizomes, followed by those in the pericarps and arillate seeds, and the lowest in the stems and exarillate seeds. This study can provide data support for the comprehensive development and rational application of non-medicinal parts of PPC.
