Quick answer: Maoming, in Guangdong province, was the imperial agarwood source of Tang and Song dynasty China and the origin point of much of the oud that reached Arab perfumers via the Silk Road. After 150 years out of the global spotlight, Maoming's 1985 cultivation program restored it as the world's largest CITES-certified Aquilaria sinensis producer.
For centuries, the global perfume trade has looked to Southeast Asia for Oud. However, recent botanical research and historical records point to a specific region in Southern China-Maoming-as the true birthplace of the most resinous agarwood in existence.
Scientific Insights: The Aquilaria Sinensis Advantage
According to studies published in the Journal of Ethnopharmacology, the Aquilaria sinensis species native to Maoming produces a unique chemical profile. Compared to its relatives in Indochina, Maoming oud contains a higher concentration of sesquiterpenes, the compounds responsible for the deep, long-lasting 'earthy-sweet' aroma that defines high-end perfumery.
Research indicates that the specific soil pH and humidity levels in Maoming's ancient forests trigger a more intense defense response in the trees, leading to the formation of dense, "sinking-grade" resin that is up to 30% heavier than average oud nuggets.
Scientific Fingerprint of Maoming Oud
Modern analytical chemistry has further distinguished Maoming's harvest through the identification of specific chemical markers. Scholarly research has highlighted the presence of 2-(2-phenylethyl)chromones as a unique and definitive fingerprint for A. sinensis sourced from this region. These chromones are not only central to the wood's distinctive olfactory profile but also serve as a benchmark for authenticity in an increasingly crowded global market.
Furthermore, clinical studies distinguish Maoming Oud by its "cool" medicinal profile. Unlike the more tropical and spicy varieties found in Indochina, the Chinese A. sinensis is traditionally favored in pharmacology for its digestive and sedative properties, a direct result of its specific sesquiterpene and chromone balance.
| Component Class | Aquilaria sinensis (Maoming/Qi-Nan) | Aquilaria crassna (Vietnam) | Primary Marker Compounds |
|---|---|---|---|
| Sesquiterpenoids | 55.4% - 72.8% | 64.2% - 81.5% | ?-guaiene, ?-agarofuran, Agarospirol |
| 2-(2-Phenylethyl)chromones | 18.3% - 26.5% | 7.4% - 14.8% | 2-(2-phenylethyl)chromone, 6-hydroxy derivatives |
| Aromatic Compounds | 5.2% - 10.1% | 2.1% - 5.5% | Benzylacetone, Anisic acid |
| Relative Diversity | High (>60 PEC derivatives) | Moderate (>30 PEC derivatives) | N/A |

Preserving a Legacy
At SilkwayOud, we work with sustainable plantations that follow traditional "drilling" and "aging" methods, ensuring that our Sinking-Grade Nuggets meet the standards of 10th-century Imperial tribute wood.

Why "forgotten"?
For 700 years, from the Tang dynasty through the Qing, Maoming was the primary Chinese source of agarwood exported via Guangzhou. Arab merchants knew it. Ottoman court inventories listed it. Then through the late 19th and 20th centuries, war, political upheaval, and overharvesting nearly erased the legitimate trade. The wood kept growing. The world stopped looking.

| 2021 | Maoming Agarwood granted GI status |
| 2024 | Maoming holds ~60% of China's CITES-registered production area |
Frequently asked questions
Where exactly is Maoming?
A coastal prefecture in southwestern Guangdong province, China. Roughly 400 km west of Guangzhou.
Why did Maoming lose its global position?
19th-century overharvesting, 20th-century political disruption, and the rise of Southeast Asian wild stocks that flooded the global market until they too collapsed.
Is Maoming oud the same species as Vietnamese or Cambodian oud?
No. Maoming produces Aquilaria sinensis. Southeast Asian oud is mostly A. crassna or A. malaccensis. Different species, different scent profiles.
How can I verify a product is genuinely from Maoming?
CITES paperwork includes export province. SilkwayOud ships all orders above 10g with traceable permit references back to the specific Maoming plantation.
