What is Maslinic acid?
Maslinic acid powder is a versatile natural ingredient known as triterpene.
Natural sources of Maslinic Acid
There are different specifications and natural sources for maslinic acid.
Generally speaking, there are three main sources:
- Olive (Olea europaea) High concentration of maslinic acid is found in the waxy skin of olives, reaching as high as 80%.
- Crataegus pinnatifida (aka Chinese hawthorn, or Hawthorn berry)
- Eriobotrya japonica (Thunb.) Lindl (loquat leaves)
Eriobotrya japonica is unique to China, and you’ll find all suppliers who supply maslinic acid from loquats are from China.
According to Wikipedia, Maslinic acid is a byproduct of oil extraction from dry olive-pomace oil. It seems that olive is the main source of mass production of maslinic acid powder. However, it is probably not. It’s difficult to isolate maslinic acid from olive leaves or oils. And the cost is also quite high.
In reality, the loquat leaf extract is the best source.
Loquat source is new to the market; Loquat is abundant; the production technology is easy to operate.
Maslinic acid specifications
Maslinic acid 10% is the most popular specification.
Of course, 20%, 30%, 50%, 70%, 98% are all available upon your reuqest.
Cima is able to offer maslinic acid powder from both loquat leaf extract and olive (Olea europaea), but the pricing is quite different.
Chemical constituents of loquat leaf extract
As the origin of loquat plants, China has cultivated loquat for more than 2000 years. Loquat is now commercially cultivated in more than 30 countries worldwide.
China is now the largest producer of loquat fruit with a cultivation area of about 170,000 ha and an output of about one million tons per year, accounting for more than 70% of the world’s total loquat production.
The main active triterpenes in Eriobotrya japonica are oleanolic acid, ursolic acid, corosolic acid, and maslinic acid.
Based on other statistics on loquat leaves from 10 regions in China,
the content of maslinic acid ranged from 0.244% to 0.571%.
The content of corosolic acid ranged from 0.352% to 0.808%.
The content of oleanolic acid ranged from 0.146% to 0.192%.
The content of ursolic acid ranged from 0.548% to 0.834%.
