| Mucilages are hydrocolloid that form the complex polysaccharides (consisting of sugars and uronic acids) and glycoproteins which found in many higher plants. This study aimed to correlate anatomical features of mucilage-secreting cells with phytochemical mucilage content in three varieties of Malva sylvestris -var. mauritiana, var. eriocarpa and var. sylvestris, Malva parviflora var. microcarpa and Althaea ludwigii, collected from distinct ecological regions in Iran. Leaf, petal, fruit and root tissues were analyzed using light microscopy and Ruthenium Red staining for anatomical characterization, while mucilage content was quantified via hot water extraction (HEM). Results revealed that mucilage-secreting cells were predominantly located in the epidermis of leaves and petals, with the highest density and cell area observed in var. mauritiana. Phytochemical analyses confirmed that leaves contained the highest mucilage content (up to 27. 86% DW), followed by petals, roots, and fruits. A significant positive correlation was found between anatomical parameters (cell number and area) and extracted mucilage yield, validating microscopic analysis as a rapid, cost-effective predictive tool. Ecological altitude was identified as a key factor influencing mucilage production, with the higher yields observed in populations from higher elevat region (e.g., Gilavand). No significant diagnostic anatomical characters were found among varieties, except for the presence of prismatic calcium crystals in Malva sylvestris var. sylvestris roots, indicating limited taxonomic value of anatomical traits at infraspecific levels. These findings support the use of anatomical screening for preliminary selection of high-yield mucilage sources in pharmaceutical applications. | ||
