Spring star anise flowers are harvested from February to April — the early season when star anise trees bloom for the first time after dormancy. This is considered the best time of year for premium-quality star anise, as the essential oil (Anethole) content peaks, the seeds are large and uniform, the aroma is pungent and spicy, and impurities are minimal.

Active Compounds and Scientific Value of Spring Star Anise Flowers

Spring star anise flowers contains numerous valuable compounds with high medicinal and practical applications:

Anethole (80–90%): the primary component in star anise essential oil, known for antibacterial, anti-inflammatory, and antispasmodic effects on the digestive tract.
Limonene and Linalool: support respiratory health, reduce stress, and provide strong antioxidant properties.
Shikimic Acid: a precursor in antiviral drug production (Oseltamivir – Tamiflu), highly valued in modern medicine.

According to the Vietnam Institute of Medicinal Materials, spring-harvested star anise has 15–25% higher essential oil content than autumn-harvested anise, with a brighter color and more intense aroma.

Strict Harvesting and AD Drying Process for Premium Quality

Kentary’s spring star anise flowers are produced using a strict protocol from the renowned star anise region of Lạng Sơn:

• Hand-harvested early in the morning, when the flowers have just bloomed, to preserve their structure and essential oil.
• Air drying (AD) at a stable temperature of 50–55°C for 36–48 hours.
• Careful sorting: removing broken, moldy, or deformed flowers – only keeping whole flowers with at least 8 petals.

After drying, the product achieves a standard moisture content of ≤5%, making the flowers crisp and mold-resistant under normal storage conditions.
