Abstract
Objective: To establish the seed quality classification standard of Vaccariae Semen. Method: 34 batches of Vaccariae Semen seeds samples from different producing areas of the whole country were selected. the seed purity, 1 000-grain weight, water content and the germination rate of the seeds samples were measured. K-means analysis was applied for the date analysis. The primary seed quality classification standard of Vaccariae Semen was formulated. Result: Seed purity and seed germination rate were selected as the primary indicators, and the other indicators provide the important reference, the Vaccariae Semen seeds were classified into 3 grades. Conclusion: The quality classification standard of Vaccariae Semen seeds were initially established and it can be used as the reference standard.
Highlights
Vaccariae Semen is the Vaccaria segetalis (Neck.) Garcke. dried matured seeds of Caryophyllaceae as the commonly used traditional Chinese medicine, its bitter taste, belong to the liver and stomach channel
The quality classification standard of Vaccariae Semen seeds were initially established and it can be used as the reference standard
The purity of different batches of Vaccariae Semen seeds samples were 94.98%~99.61%, at a high standard, on average 97.98%; 1 000-grain weight were 3.605∼4.840 g, on average 4.338 g, there are 5 batches samples lower than 4.0 g, of which four of them are from Neiqiu County Hebei Province, may be related to growing conditions; Water content of these batches were all lower than 11.0%, they were between 9.22% to 10.65%, on average 9.79%, different batches has small differences
Summary
Vaccariae Semen is the Vaccaria segetalis (Neck.) Garcke. dried matured seeds of Caryophyllaceae as the commonly used traditional Chinese medicine, its bitter taste, belong to the liver and stomach channel. Seeds mainly contains triterpenoid saponins, flavonoids glycosides, cyclic peptide, lipid and fatty acid, monosaccharide and so on [2], can resist early pregnancy, antitumor, excite uterus, promote the secretion of milk and other pharmacological effects [3]. Vaccariae Semen distributed in North China, East China, China’s northeast,northwest and southwest, mainly produce in Hebei, Shandong, Liaoning, Heilongjiang Provinces, the largest origin is Hebei province [4]. In production Vaccariae Semen propagated by seeds, but except Gao Xiaojuan was reported the Vaccariae Semen seed quality about Guyuan Ningxia, currently at home and abroad the research reports were fewer [5]. The primary seed quality classification standard of Vaccariae Semen was established, and provide theoretical basis for seed quality evaluation
