The dry leaf of Turpinia arguta (Lindl.) Seem. is used in traditional Chinese medicine as a quick-acting product for sore throat and pharyngitis relief. Samples T. were collected from 40 different habitats mostly located Jiangxi Province, appearance traits matter yield analyzed. HPLC was to quantify ligustroflavone rhoifolin, the pharmacological-quality markers this species, according 2020 Edition Pharmacopoeia. correlations between leaf-measurable traits, rhoifolin contents, climate factors subsequently assessed using Pearson’s two-tailed correlation test redundancy analysis. highest yields found locations S(G-mt), Q(J-t), A(X-t). Ligustroflavone contents ranged 0.023% 1.336% 0.008% 0.962%, respectively; levels compounds A(X-t) Y(B-mt). Leaf morphology influenced by mean temperature warmest quarter, while thickness affected minimum coldest month, precipitation seasonality, solar radiation. Larger thicker leaves predicted higher under southern conditions, such those Anyuan Quannan counties. Our findings suggest that enhancing diurnal range implementing appropriate shading during cultivation can enhance arguta.

Multi-Indicator Comprehensive Quality Evaluation of Turpinia arguta (Lindl.) Seem Herbs at Different Harvesting Periods

Agronomy, Journal Year: 2024, Volume and Issue: 14(11), P. 2658 - 2658

This study aimed to investigate differences in the leaf biomasses, chemical compositions, and pharmacological activities of Turpinia arguta histocultured seedlings live at different harvesting periods (S1, S2, S3, S4) order determine optimal period. Eleven indexes, including biomass, key active components, secondary metabolites, nutrient content, antioxidant activity, were evaluated by high-performance liquid chromatography colorimetric methods during periods. The weights 11 indexes calculated principal component analysis, then a comprehensive quality evaluation was performed. results showed significant contents, between highest score obtained for S4 period, indicating that T. best this time period most suitable At (S4), medicinal higher than those seedlings, importance tissue culture technology enhancing arguta. provides more novel abundant information reference determining appropriate arguta, with aim providing newer scientific guidance management herbs.
