1. Product Overview

Naruhibis® Roselle HCA Powder is a flagship branded ingredient developed by World-Way Biotechnology. It is a high-concentration hydroxycitric acid (HCA) standardized extract derived from the calyces of natural roselle (Hibiscus Sabdariffa L.) through an environmentally friendly water extraction process. With a core quality specification of ≥ 40% HCA plus Hibiscus acid, this product is specifically designed for science-based weight management and body shaping applications.

Unlike most HCA products on the market that originate from Garcinia cambogia, Naruhibis® offers a novel natural alternative with HCA concentrations 2 to 4 times higher than common commercial alternatives. The product has earned multiple internationally recognized certifications including ECOCERT, EU/USDA Organic, FSSC 22000, HALAL, KOSHER, and ISO9001, ensuring the highest quality standards.

2. Botanical & Source Profile

2.1 Botanical Identification

Roselle, also known as Hibiscus sabdariffa or Jamaican sorrel (Latin: Hibiscus Sabdariffa L.), belongs to the Malvaceae family as an annual erect herbaceous plant. Native to West Africa, it is now widely cultivated across tropical and subtropical regions worldwide, including Yunnan, Guangxi, Guangdong, and Hainan provinces in China. The global annual production of roselle exceeds 500,000 tons.

2.2 Extraction Part & Raw Material Quality

The extraction material for Naruhibis® Roselle HCA Powder is the fleshy calyx of the roselle flower. World-Way Biotechnology rigorously selects roselle raw materials from 15 premium producing regions globally, ensuring exceptional quality and supply stability from the source. Analytical data shows that the selected roselle raw material contains nearly twice the HCA content of common commercial varieties.

2.3 Traditional Uses

Roselle has a long history of use in food and traditional medicine worldwide. Traditionally valued for its rich anthocyanin content and distinctive tart flavor (similar to cranberry or rhubarb), it has been widely used as a natural red colorant and acidulant in teas, juices, jams, and beverages. In African and Asian traditional medicine, roselle has been used to support healthy blood pressure, aid digestion, and relieve cold symptoms. Modern science has since validated and expanded these traditional applications.

3. Active Ingredients & Quality Standards

3.1 Key Active Components

The primary bioactive compounds in Naruhibis® Roselle HCA Powder include:

· Hydroxycitric Acid (HCA ≥ 40%): The key active compound that inhibits ATP-citrate lyase, blocking carbohydrate-to-fat conversion at the source.

· Hibiscus Acid: A unique organic acid specific to roselle that synergistically enhances the overall weight management effect.

· Anthocyanins: Natural pigments with antioxidant properties, contributing to overall health benefits.

· Polyphenolic Compounds: Including protocatechuic acid and gallic acid, providing additional antioxidant and anti-inflammatory support.

3.2 Quality Standards

The product appears as a yellow powder with excellent water solubility, making it highly versatile for various formulation types. Manufacturing takes place in Class 100,000 clean rooms using pure water extraction — a safe and environmentally friendly process. The complete production workflow includes: raw material inspection → water extraction → filtration → concentration → UHT sterilization → drying → grinding → blending → sieving → packaging, with rigorous quality control at every step to preserve active compounds and ensure product purity.

4. Health Benefits & Mechanisms of Action

Naruhibis® Roselle HCA Powder exerts a comprehensive multi-target weight management effect, supported by cellular, animal, and clinical studies.

4.1 Targeted Inhibition of Fat Synthesis

The high-concentration HCA potently and competitively inhibits ATP-citrate lyase, a key enzyme in fat biosynthesis. Cell studies confirm significant reduction of this enzyme and acetyl-CoA levels in primary cells, directly preventing the conversion of excess dietary carbohydrates into stored fat.

4.2 Appetite Regulation via Neurotransmitter & Hormone Modulation

Dual mechanism for appetite control: First, it elevates brain serotonin (5-HT) levels, promoting a feeling of satisfaction and reducing compulsive eating urges. Second, it increases leptin receptor mRNA expression and signaling activation, significantly improving leptin sensitivity to enhance satiety and reduce hunger.

4.3 Digestive Enzyme Inhibition

In vitro studies demonstrate significant inhibition of α-amylase and α-glucosidase (blocking carbohydrate/sugar absorption) as well as pancreatic lipase (blocking fat absorption), providing a dual anti-absorption mechanism that effectively reduces caloric intake.

4.4 Metabolic Activation & Fat Burning

By modulating PPAR signaling pathways (particularly PPARα and PPARγ), the extract promotes fatty acid oxidation and reduces fatty acid synthesis, effectively decreasing stubborn fat accumulation while supporting healthy cholesterol metabolism and reducing inflammation.
