Here is my solution:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<p id="content">
Rakiya (Bulgarian brandy) is home-made liquor (alcoholic drink). It can be made of grapes, plums or other fruits
(even apples).
</p>
<p id="holder">
Lorem ipsum dolor sit amet, (consectetur adipiscing elit), sed do eiusmod (tempor) incididunt ut labore (et dolore
magna) aliqua.
</p>
<script>
function extract(elementId){
let para = document.getElementById(elementId).textContent;
let pattern=/\(([^)]+)\)/g;
let result = [];
let match = pattern.exec(para);
while(match){
result.push(match[1]);
match=pattern.exec(para);
}
return result.join("; ")
}
</script>
</body>
</html>
