Phenotype, Squalene, and Lanosterol Content Variation Patterns During Seed Maturation in Different Leaf-Color Tea...

Area of Science:

• Agricultural Science
• Plant Biochemistry
• Nutraceuticals

Background:

• Squalene and lanosterol are bioactive compounds found in tea seed oil.
• Their concentrations vary with tea cultivar and fruit maturity.
• Leaf-color specific tea cultivars are gaining popularity, but their fruit characteristics are underexplored.

Purpose of the Study:

• To investigate phenotypic changes in tea seeds during maturation.
• To examine the variation patterns of squalene and lanosterol in different tea cultivars.
• To compare squalene and lanosterol levels between leaf-color specific and green-leaf tea cultivars.

Main Methods:

• Analysis of 15 tea cultivars with varying leaf colors.
• Monitoring of seed maturation and phenotypic changes.
• Quantification of squalene and lanosterol content.

Main Results:

• Crude water, dry kernel, and oil content correlated with seed maturity.
• Lanosterol content decreased with increased maturity.
• Squalene content fluctuated during maturation, then decreased.
• Leaf-color specific cultivars showed higher squalene and lanosterol at full maturity.

Conclusions:

• Seed maturity significantly impacts squalene and lanosterol levels.
• Leaf-color specific tea cultivars are a richer source of these bioactive compounds at maturity.
• Further research into tea fruit characteristics is warranted.
