Import Blueberry Leaf Extract — Buy in wholesale FOB from Supplier in China

Hunan Sunshine Bio Tech Co., Ltd. supplies Blueberry Leaf Extract characterised by pterostilbene as the main ingredient, with testing by UV method for purity and efficacy verification. The extract derives specifically from blueberry leaves rather than fruit, where pterostilbene and related stilbenoids concentrate in higher amounts relative to fruit tissue. The product presents as a dark purple powder, with the colour intensity indicating substantial anthocyanidin presence alongside the stated pterostilbene marker. Buyers should request the specific pterostilbene content percentage, as the source description emphasises this compound without quantifying standardisation.

Leaf extraction targets distinct phytochemical profiles compared to fruit extracts, with higher polyphenol diversity and lower sugar content. Pterostilbene (trans-3,5-dimethoxy-4'-hydroxystilbene) is a methylated resveratrol analogue with reported bioavailability advantages, though buyers should verify claimed anti-inflammatory and anti-cancer properties are substantiated by supplier documentation rather than marketing assertions. Standard industry practice for leaf extracts includes specification of drying method (freeze-dried versus spray-dried), particle size, and extraction solvent. The UV test method mentioned is standard for total stilbene quantification, though HPLC with reference standard provides more specific pterostilbene identification and quantification.

Primary applications span dietary supplement capsules and tablets, functional food powders, and herbal product formulations where leaf-derived antioxidants are preferred over fruit sugars. The dark purple colour suggests potential for natural colourant applications in beverages and confectionery. Changsha's location in Hunan Province, central China, positions the supplier within reach of Wuhan and Shanghai ports for export logistics. The zero response rate and zero average response hours indicate buyers should establish direct communication channels early and confirm current production status, as platform-based messaging may not yield timely replies.

Hunan Sunshine Bio Tech Co., Ltd. is located at 903-904, Building C3, Lugu Yuyuan, No. 27 Wenxuan Road, High-Tech Development Zone, Changsha, Hunan Province, China, postal code 410000. The address situates the company within Changsha's high-technology industrial zone, suggesting access to regional research institutions and biotech infrastructure. The trust tier registers as harbour, with zero response rate and zero average response hours, indicating limited active platform engagement and a need for persistent direct outreach.

The company profile contains no stated year of establishment, employee count, annual revenue, production capacity, or export history. The source description mentions ISO and SGS certification, but buyers must independently verify certificate numbers, scope, and current validity, as these claims are not substantiated with documentation in the available data. No specific MOQ, pricing, lead time, or packaging details are provided. The reference to 'flexible trading options' and 'competitive MOQ' requires concrete confirmation, as these are marketing phrases without attached numbers.
