| Abstract: | 26 accessions including six species of golden camellia,different phenotypes of Camellia chrysantha and C.chrysantha collected in different months were selected as the research materials.The simultaneous determination of rutin,quercetin,luteolin and kaempferiae by HPLC and the determination of tea polyphenols,flavonoids,total polysaccharides and total saponins by ultraviolet spectrophotometric were established and optimized.The quality of leaves of golden camellia from different sources was comprehensively evaluated based on the combination of the principal component comprehensive scores and clustering analysis of the eight biochemical components.There were differences in the content of the eight components in different sources.The content of the eight components in C.nitidissima was higher,followed by that of C.perpetua and C.chrysantha.The content of total saponins,total flavonoids and total polysaccharides in 8-year-old C.chrysantha collected from January to December all showed the rule of ascend ing-descending-ascending-descending,and reached the highest value in October.The order of the principal component comprehensive score of the 5-year-old different species(S1-S14)was as follows:C.nitidissima>C.perpetua>C.chrysantha(large flowers,many flowers,not cold-resistant,yellow flowers and large,sharp fruits)>C.euphlebi>C.impressinervis>C.nitidissima var.microcarpa.The order of the comprehensive scores of the main ingredients of the 8-year-old havested in different months(S15-S26)was October>February>March>April>May>July>June>January>August>December>November>September.Besides,the ranking of the comprehensive scores of large buds,large flowers,multi-golden flower and February to April and October harvested C.chrysantha was higher and at the first 10 ranks.Cluster analysis classified the 26 accessions could be classified into five categories.In summary,the quality of golden camellia was affected by variety,tree age and harvest time.The comprehensive biochemical compositions of C.nitidissima,C.perpetua and C.chrysantha with phenotype of large flower buds,many flowers,not cold resisdence,yellow and big flowers was better.It approved that the best harvest period of C.chrysantha was from February to April and October.The established multi-index quantitative analysis combined with chemometric analysis would provide a reference for biochemical evaluation of golden camellia. |
