Extraction Methods of White Mulberry

Historically, white mulberry leaves were processed using traditional maceration and simple water infusions, where the leaves were soaked in solvents or boiled to create medicinal teas. Maceration remains a foundational technique, involving the soaking of powdered leaves in solvents like ethanol or methanol for extended periods to release phytochemicals such as flavonoids and alkaloids. Traditional extraction often concluded with basic filtration and evaporation to concentrate the active components.

Modern commercial and industrial production has advanced to more efficient and selective methods. Water extraction is now often optimized using twin-screw continuous extractors and vacuum evaporation to preserve heat-sensitive compounds like 1-deoxynojirimycin (DNJ). Furthermore, innovative non-conventional techniques have emerged, including ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE), which significantly reduce extraction time and energy consumption while increasing yields. For high-purity applications, supercritical CO2 extraction is utilized, often with ethanol as a cosolvent, to capture delicate bioactive molecules without leaving toxic solvent residues. Recent developments also include the use of ultrafiltration and nanofiltration membranes to decolorize and concentrate extracts while retaining essential active components.

The White Mulberry note is an emerging star in modern perfumery, valued for its ability to balance mild, earthy sweetness with bright, green, and herbaceous facets. Because the note is newer to the Western perfumer's palette, it often appears in niche or artisanal compositions seeking a sophisticated, unique fruit accord that avoids the typical sweetness of more common fruits. Its complex profile allows it to blend seamlessly into various categories, lending a vibrant, natural freshness to compositions.

One notable use of the White Mulberry note can be found in the fragrance **Morus Alba** by Laboratorio Olfattivo. This composition is dedicated entirely to the subtle complexity of the mulberry tree, utilizing the note's delicate fruitiness and green undertones to create a luminous, cool, and refined scent. The fragrance emphasizes the white mulberry's inherent freshness, often pairing it with musks and light woods to ensure its ephemeral quality endures.

Another fragrance where this note provides a subtle, sophisticated twist is **Eau de Camille** by Annick Goutal. While this scent focuses on notes like honeysuckle and foliage, some contemporary interpretations or variations feature a white mulberry accord to enhance the soft, green, and slightly sweet woodland feeling. This use demonstrates the white mulberry's versatility, acting as a supporting note that bridges green accords with a whisper of gentle, non-cloying fruitiness, contributing to an overall sense of natural elegance.

Seasonality of White Mulberry The white mulberry tree follows a distinct annual cycle, with blooming typically occurring in the spring from April to May. As the season transitions into early summer, the fruit begins to ripen and reach its peak, generally from June through July or August depending on the region. During this window, the berries transform from small green clusters into plump, juicy fruits that can range in color from white and pink to dark purple. In some climates, the harvest may begin as early as late May and extend through midsummer, while the tree provides a dense canopy of lush green foliage throughout the hot summer months before entering dormancy in the winter.
