Centella Hydroponic Medium for Consistent Madecassoside Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centella asiatica, a medicinal plant with valuable ingredients like madecassoside and asiaticoside, is difficult to cultivate and harvest in Korea due to limited habitat and environmental degradation, leading to reliance on imports and variable metabolite production, and artificial synthesis is complex and costly.
Innovation Solution
A culture medium composition and hydroponic cultivation method, including specific macro- and microelement ratios, deep flow technique, and controlled environmental conditions, to enhance the growth and increase the production of madecassoside and asiaticoside in Centella asiatica.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Centella asiatica is cultivated in open fields in Korea, then the plant can grow in natural conditions, but the production amounts and functional ingredients vary greatly depending on season and harvest time
Solution Approach 1:
The patent applies parameter changes by precisely controlling nutrient solution composition (macroelements N, P, K, Ca, Mg, S in specific ratios), environmental conditions (temperature 20-30°C, humidity 60-80%, light intensity 10000-20000 lux), and harvest timing to achieve consistent high-level metabolite production regardless of seasonal variations
2Ease of manufacture
If Centella asiatica is collected from natural habitats, then the plant can be obtained without cultivation costs, but the natural habitat is limited and environmental degradation makes collection difficult
Solution Approach 1:
The patent creates an artificial copy of optimal growth conditions through controlled environment cultivation with standardized nutrient solutions and environmental parameters, reproducing the ideal conditions that would naturally occur without being limited by actual natural habitats
3Manufacturing precision
If artificial synthesis is used to produce madecassoside and asiaticoside, then the production can be controlled, but the synthesis is complex and expensive
Solution Approach 1:
The patent employs self-service by providing optimized nutrient solutions containing specific macroelements and microelements that enable the plant to autonomously synthesize high levels of madecassoside and asiaticoside, eliminating the need for complex external synthesis processes
