This study was carried out to assess the spermicidal action of hexane extract from the fruits of Piper longum Linn. The sperm immobilisation studies showed that 20 mg/mL of hexane extract was able to immobilise sperms completely within 20 s. The sperm revival test revealed that the effects were spermicidal as sperm immobilisation effect was irreversible. There was also a significant reduction in sperm viability in the treated group in comparison to the control. The hypo-osmotic swelling of these sperms was significantly reduced, indicating that the hexane extract may probably cause injury to the sperm plasma membrane. Hence, this study showed that the hexane extract of P. longum possesses potential contraceptive spermicidal activity in vitro.

, a special economic aquaculture species in China, is valued highly for its medicinal and nutritional benefits. However, the muscle of farmed exhibits a strong off-flavor, resulting in poor flavor quality. To enhance the flavor quality of the meat, this study examined the volatile compounds in muscle by establishing identification methods for these volatile odor compounds and comparing the differences between the two aquaculture modes.

Background: Edible insects are used for consumption and traditional medicine due to their rich bioactive compounds. This study examined the bioactive compounds and inhibitory effects of crude extracts from Bombyx mori and Omphisa fuscidentalis on α-glucosidase, α-amylase, acetylcholinesterase (AChE), and tyrosinase. Fatty acids, including n-hexadecanoic acid and oleic acid, were identified in the extracts and evaluated for their inhibitory potential against the enzymes in vitro and in silico.

Commercial ascorbyl-6-O-esters (AEs) are composed of saturated fatty acids with relatively high melting points, resulting in limited solubility in lipophilic media. Therefore, a lipase-catalysed synthesis and purification method for ascorbyl-6-O-oleate (AO) was proposed in this study. The esterification synthesis (i.

Objective: Oral squamous cell carcinoma (OSCC) is the prevailing type of oral cancer, representing poor prognosis and elevated mortality rates. Major risk factors for OSCC include the use of tobacco products, alcohol consumption, betel quid chewing, and genetic mutation. is traditionally consumed by cancer patients to fight against tumor growth.
