1. What is Lotus Leaf Extract (Nuciferine)?
Lotus Leaf Extract is derived from the dried leaves of Nelumbo nucifera (sacred lotus), a plant used for centuries in traditional Chinese herbal medicine. The principal bioactive alkaloid is Nuciferine (molecular formula C19H21NO2, CAS 475-83-2), which is widely researched for its role in lipid metabolism, glucose balance, and antioxidant activity.
As a leading plant extract manufacturer in China, Shaanxi Green Bio-Engineering Co., Ltd. produces Lotus Leaf Extract in four standardized specifications — 2%, 3%, 5%, and high-purity 98% Nuciferine — to meet the diverse needs of formulators, contract manufacturers, and research laboratories around the world

4.1 Weight Management & Slimming Products
Nuciferine is one of the most sought-after herbal ingredients for natural weight-management formulas.

Lotus leaf tea and slimming capsules containing 3% or 5% Nuciferine are particularly popular in the North American and European supplement markets.
4.2 Dietary Supplements & Nutraceuticals
Formulators use Lotus Leaf Extract in antioxidant, liver-support, and cardiovascular wellness capsules. The 2% and 3% grades blend well with other herbal ingredients such as green tea extract, Garcinia cambogia, and chromium picolinate for synergistic metabolic formulas.

The cosmetic industry values Lotus Leaf Extract for its antioxidant and skin-conditioning properties. It is incorporated into anti-aging serums, whitening creams, anti-acne treatments, and face masks. The 2% and 3% grades are water-soluble and easy to incorporate into emulsion systems.
