Embodiment 1
[0036] Take 300g of fruiting stems of dragon claw, soak them in 2400ml of water for 24h, and then heat and reflux at 80°C for 4h to extract.
[0037] Cool after the extraction, and filter with a 40-mesh filter to obtain the filtrate. The filtrate is separated from the solid and liquid by a centrifuge, and the supernatant is collected;
[0038] Rotary evaporation was carried out at 70° C. and a vacuum degree of 0.01 MPa, and concentrated to obtain 119 g of the extract of S. japonica.
Embodiment 2
[0040] Take 300g of fruit stem of dragon claw, add it into 2100ml of 50wt% ethanol aqueous solution, and then heat and reflux for extraction at 60°C for 6h.
[0041] Cool after the extraction, and filter with a 40-mesh filter to obtain the filtrate. The filtrate is separated from the solid and liquid by a centrifuge, and the supernatant is collected;
[0042] Rotary evaporation was carried out at 45° C. and a vacuum degree of 0.02 MPa, and concentrated to obtain 108 g of the extract of Scutellaria japonicus.
Embodiment 3
[0044] Take 300g of fruit stem of dragon claw, add it into 1500ml of 70wt% ethanol aqueous solution, and then heat and reflux for extraction at 80°C for 2h.
[0045] Cool after the extraction, and filter with a 40-mesh filter to obtain the filtrate. The filtrate is separated from the solid and liquid by a centrifuge, and the supernatant is collected;
[0046] Rotary evaporation was carried out at 40° C. and a vacuum degree of 0.04 MPa, and concentrated to obtain 95 g of the extract of Scutellaria japonica.

Abstract
The invention provides a hovenia acerba fruit stem extract and a preparation method and application thereof. The preparation method includes: adopting ethanol water or water as an extracting agent forextracting hovenia acerba fruit stems to obtain extract liquid; filtering and separating to obtain supernatant liquid of the extract liquid; concentrating the supernatant liquid to obtain the hoveniaacerba fruit stem extract. The hovenia acerba fruit stem extract is used as a natural tobacco additive to improve smoking quality of tobacco raw materials such as cut stems, slices or tobacco leavesand is capable of enriching and thickening smoke, improving aroma quality and quantity, reducing smoke pungency and dryness to make smoke gentle and delicate, and covering miscellaneous smell.
Description
technical field [0001] The invention relates to a tobacco additive and a preparation method thereof, in particular to a natural tobacco additive capable of effectively improving the smoking quality of tobacco raw materials and a preparation method thereof. Background technique [0002] Jujube, also known as Longevity Fruit, Hovenia dulcis, Longclaw, belongs to Rhamnaceae, and its twigs, the back of young leaves, petioles and inflorescence rachis have pubescence at the beginning, and then fall off. The leaves are elliptic-ovate, broadly ovate or heart-shaped-ovate. The stalk contains a lot of glucose and potassium malate, sweet after frost, can be eaten raw or brewed wine; the wood has moderate hardness and beautiful texture, and is used for construction, furniture and art crafts. Distributed in Henan, Shaanxi, Gansu Longnan, Jiangxi, Anhui, Zhejiang, Guangdong, Fujian, Hubei, Hunan, etc. The shape of the fruit resembles a swastika, so the tree is called a longevity fruit t...
