“…In two cases, between Mn total and water-extractable Mn, as well as between Cu total and water-extractable Cu, the correlation was strong and the correlation coefficients calculated for these pairs were equal or higher than 0.8, respectively. Also quite high correlation occurred between total N and total P, which is justified by their synergistic participation in the biosynthesis of important for plants metabolites, as reported in the literature [20].…”

S u m m a r yIn the study, the relationships were investigated among N, P, Fe, Zn, Mn and Cu, in medicinal plant raw materials (herbal bags) and their water-soluble chemical forms in infuses. 42 independent samples of plant materials were chosen, represented by different morphological plant parts as herbs, leaves, flowers and fruits. The elements were determined by UV/Vis spectrometry (non-metals), and FAAS (metallic elements) after previous mineralization of plant samples (total concentrations), and directly in herbal teas (water-extractable forms). Most frequently the correlations between non-metals and Zn and Mn occurred, both between their total contents the water-extractable forms. Statistically significant correlations were also found in pairs: Zn-Mn, Fe-Zn, Mn-Fe, and Cu-Zn. Application of multivariate analysis revealed that cluster analysis grouped the studied samples into clusters with similar levels of the analyzed elements, and principal component analysis allowed the identification of water-extractable Zn, P-PO 4 and water-extractable Cu as the most crucial factors determining the differentiation of the studied plant samples.

“…These phenomena have been observed in Pseudostellaria heterophylla (Yin et al 2013), Panax ginseng (Huang et al 2010), and Bupleurum chinense DC. (Zhu et al 2009). Phosphate plays an important role in energy metabolism and in the production of biomass in plants.…”

Phosphate starvation promoted the accumulation of phenolic acids by inducing the key enzyme genes in Salvia miltiorrhiza hairy roots

Phosphate starvation increased the production of phenolic acids by inducing the key enzyme genes in a positive feedback pathway in Saliva miltiorrhiza hairy roots. SPX may be involved in this process. Salvia miltiorrhiza is a wildly popular traditional Chinese medicine used for the treatment of coronary heart diseases and inflammation. Phosphate is an essential plant macronutrient that is often deficient, thereby limiting crop yield. In this study, we investigated the effects of phosphate concentration on the biomass and accumulation of phenolic acid in S. miltiorrhiza. Results show that 0.124 mM phosphate was favorable for plant growth. Moreover, 0.0124 mM phosphate was beneficial for the accumulation of phenolic acids, wherein the contents of danshensu, caffeic acid, rosmarinic acid, and salvianolic acid B were, respectively, 2.33-, 1.02-, 1.68-, and 2.17-fold higher than that of the control. By contrast, 12.4 mM phosphate inhibited the accumulation of phenolic acids. The key enzyme genes in the phenolic acid biosynthesis pathway were investigated to elucidate the mechanism of phosphate starvation-induced increase of phenolic acids. The results suggest that phosphate starvation induced the gene expression from the downstream pathway to the upstream pathway, i.e., a feedback phenomenon. In addition, phosphate starvation response gene SPX (SYG1, Pho81, and XPR1) was promoted by phosphate deficiency (0.0124 mM). We inferred that SPX responded to phosphate starvation, which then affected the expression of later responsive key enzyme genes in phenolic acid biosynthesis, resulting in the accumulation of phenolic acids. Our findings provide a resource-saving and environmental protection strategy to increase the yield of active substance in herbal preparations. The relationship between SPX and key enzyme genes and the role they play in phenolic acid biosynthesis during phosphate deficiency need further studies.

“…Effects of nutrients and nutrient ratios on many food and medicinal crop plants, such as soya bean, thyme, wheat cultivars, barley, spinach and pelargoniums, have been studied. In most cases, a positive result in growth is noticed with the addition of some macro-nutrients such as N, P, K, Mg or Ca [13][14][15][16][17][18][19][20][21]. It is therefore crucial that adequate plant nutrition and soil pH levels are met for any given plant so that the cell's functioning is not impeded.…”

Salvia chamelaeagnea (Lamiaceae) is a slow growing water-wise evergreen shrub originating from the western province of South Africa. It is an attractive landscape, and S. chamelaeagnea is a medicinal plant. It is important to develop enhanced cultivation protocols that could result in high yield and high-quality medicinal materials. Chlorophyll is a fundamental part of the light-dependent reactions of the photosynthesis process. This chapter investigates the effects of four phosphorus concentrations and three pH levels of supplied irrigated water on the production of chlorophyll A, chlorophyll B, total chlorophyll, leaf colour and the nutrient uptake of S. chamelaeagnea grown in hydroponics over an 8-week period at the Cape Peninsula University of Technology. The treatments of pH 4, pH 6 and pH 8 at 31, 90, 150 and 210 ppm of phosphorus were received by 12 groups of plants and were replicated 10 times. The results indicated that at pH 4, P fertilization significantly (P < 0.05) induced a higher chlorophyll production of S. chamelaeagnea grown in hydroponics compared to other pH treatments (pH 8 and pH 6).
