Product Overview

Citrus Aurantium Extract Powder is a highly concentrated botanical extract derived from the immature, dried fruit of Citrus aurantium L. (also known as bitter orange), a species belonging to the Rutaceae family. Renowned in traditional Chinese medicine (TCM) for its therapeutic properties, this extract is rich in bioactive compounds, with synephrine as its primary active ingredient.

Widely recognized for its metabolic support, appetite regulation, and digestive benefits, Citrus aurantium extract is a sought-after ingredient in weight management supplements, sports nutrition, and functional foods. Its natural stimulant properties make it a popular alternative to synthetic compounds in fat-burning and energy-boosting formulations.

At Botanical Essence, we provide high-purity, standardized Citrus Aurantium Extract Powder with ≥6% synephrine content, ensuring consistent potency and efficacy for manufacturers, formulators, and bulk buyers.


Botanical Source & Traditional Uses

Plant Origin & Morphology

Citrus aurantium, commonly referred to as bitter orange or Seville orange, is native to Southeast Asia but is now cultivated in various regions, including China, Spain, and the Mediterranean. The fruit used for extraction is typically hemispherical or spherical, measuring 0.5–2.5 cm in diameter.

  • Exocarp (Outer Peel): Dark green to blackish-brown, with a rough, wrinkled texture and visible oil glands.
  • Mesocarp (Middle Layer): Yellowish-white to light brown, 0.3–1.2 cm thick, containing 1–2 rows of oil chambers at the edges.
  • Endocarp (Pulp Sacs): Brown, with a firm texture and a bitter, slightly sour taste.
  • Aroma: Fresh, citrusy, and aromatic.

In traditional Chinese medicine (TCM), Citrus aurantium (known as Zhi Shi or Zhi Ke) has been used for centuries to:
Regulate Qi (vital energy) and relieve stagnation
Stimulate digestion and enhance appetite
Alleviate bloating, flatulence, and indigestion
Support respiratory health (used in remedies for coughs and phlegm)


Key Active Compounds & Bioactivity

Citrus aurantium extract contains a rich profile of bioactive flavonoids, alkaloids, and terpenes, including:

CompoundTypeKey Benefits
SynephrineProtoalkaloidFat metabolism, thermogenesis, mild stimulant
HesperidinFlavonoidAntioxidant, anti-inflammatory, cardiovascular support
NeohesperidinFlavonoidBitter taste modifier, metabolic support
NobiletinPolymethoxylated FlavoneNeuroprotective, anti-obesity
D-LimoneneTerpeneAromatic, digestive aid, potential anti-cancer properties
AuranetinFlavonoidAntimicrobial, anti-allergic
AurantiamarinCoumarinAntifungal, anti-inflammatory
LimoninLimonoidAntioxidant, cholesterol-lowering

Synephrine, the most studied compound, acts as a natural adrenergic agonist, promoting lipolysis (fat breakdown) and increasing metabolic rate without the harsh side effects of synthetic stimulants like ephedrine.
